Benign diseases of the lower reproductive tract.pptx
1. Diseases of female lower reproductive tract
The lower reproductive tract,
comprising the vulva, vagina,
and cervix, exhibits a wide
spectrum of benign and
neoplastic diseases
The external vulva includes:
Mons pubis
Clitoris
Vestibular bulbs
Lesser vestibular glands
Urethral and vaginal openings
Labia majora and minora
Vestibule
Bartholin glands
Paraurethral glands
Lateral margins of the vulva are
the labiocrural folds
Deep to the external vulva are
Superficial and deep urogenital
triangle compartments

5. Benign diseases of the vulva
• Developmental abnormalities
• Infectious conditions
6. Developmental abnormalities
Congenital
Vulvar hypoplasia, hyperplasia or duplication
Clitoral enlargement
o Clitoromegally noted at birth is suggestive of fetal exposure to excessive adrogens
It is defined as a clitoral index greater than 10mm2.
Labial fusion
Acquired
Labial hypertrophy
Labial fusion
Female genital mutilation
Epidermal inclusion cysts
7. Labial hypertrophy
• Labial width — Labia minora hypertrophy
is generally described as protuberant labial
tissue that projects beyond the labia majora.
• In current practice, a stretch width of greater
than 6 cm is generally felt to be consistent
with hypertrophy
8. Labial fusion
Also termed labial agglutination or adhesion
Prevalence
Prepubertal girls→1-5%
Female infants→10%
Cause is unknown
Hypoestrogenism
It is seen in infants and young girls and
tends to undergo spontaneous resolution at puberty
The diagnosis is made visually
Treatment
1. Expectant management
If the patient is asymptomatic, no intervention is necessary
2. Medical management
Estrogen cream therapy
3. Manual separation
4. Surgical separation
10. Tuberculosis
It most commonly affects the fallopian tubes and endometrium
Fallopian tubes are involved in 90–100 % of cases
Endometrium in 50-70% of cases
Vulvar or vaginal TB
Exceedingly rare(1–2 %)
Lesions can be ulcerative or hyperplastic
11. Condyloma Acuminatum
It is an exophytic lesion caused by infection with HPV
Most commonly types 6 and 11
It is sexually transmitted disease
When it is detected in a child, sexual abuse must be considered
The lesions are usually asymptomatic and frequently multiple and multifocal
It is not considered premalignant and do not progress to HSILs or carcinoma
Management
Topical agents
Application of dilute podophyllin,imiquimod, or concentrated halogenated acetic acid (trichloroacetic
acid)
Electrosurgery, cryosurgery, laser ablation, or surgical excision
Larger lesions and those refractory to topical treatments
The overall recurrence rate is reported as 20–30%
13. Molluscum Contagiosum
It is a viral infection of the skin
Caused by a poxvirus (molluscum contagiosum
virus)
The lesions are small, raised, and usually
white, pink, or flesh-colored with a dimple or
pit in the center
They’re usually smooth and firm
Treatment options
Curettage
Cryosurgery
Topical agents
14. Herpesvirus
HSV type 2 is more common in vulvar infection
Painful, erythematous swelling of the vulva, followed by the eruption
of clusters of papules and vesicles which evolve into exquisitely painful
ulcers
Untreated, the ulcers of the initial episode heal in approximately 2–6 weeks,
after which the virus lies dormant in regional sensory and autonomic ganglia
Antiviral agents (acyclovir, valacyclovir,or famcyclovir)
Speed healing
Decrease viral shedding
Decrease the incidence of new lesions
17. Primary skin lesion Size Description
1 Macules Lesions ≤1 cm They are nonpalpable lesions that vary in pigmentation from the
surrounding skin and they have no depression or elevations
2 Patches Lesions > 1 cm
3 Papules Lesions ≤5 mm They are palpable, discrete lesions
4 Plaques Lesions >5 mm Superficial slightly raised lesions, often formed by a confluence of papules
5 Pustules Papules containing purulent material
6 Vesicles Lesions <5 mm
Circumscribed skin lesions containing serous material
7 Bullae Lesions ≥ 5 mm
Secondary skin lesion
1 Excoriation Superficial, often linear skin erosion caused by scratching
2 Lichenification Increased skin markings and thickening with induration
3 Scale Superficial epidermal cells that are dead and cast off from the skin
4 Crust A dried exudate on the skin surface, either serum, blood or pus or a
combination
5 Fissure Deep skin split extending into the dermis
6 Erosion Superficial, focal loss of part of the epidermis
7 Ulceration Focal loss of the epidermis extending into the dermis
18. Lichen simplex chronicus
It originates from an itch-scratch cycle that leads to chronic trauma
It is often the end stage of other dermatologic conditions or irritants
Lichen sclerosus, atopic dermatitis, or psoriasis
Tight clothing,heat,sweating, or products like antiseptics,body fluids,body
soaps,condoms,emollients etc
The skin responds by thickening with exaggerated gray, leathery-appearing
skin markings termed lichenfication
Treatment involves halting the itch-scratch cycle
Topical corticosteroid ointments help reduce inflammation
Lubricants, such as plain petrolatum or vegetable oil, and cool sitz baths help
to restore the skin's barrier function
Oral antihistamine use, trimmed fingernails, and cotton gloves worn at night can help
decrease scratching during sleep
If symptoms fail to resolve, biopsy is indicated to exclude other pathology
20. Lichen Sclerosus (LS)
LS classically presents in postmenopausal women and prepubertal girls
LS is more common in the premenarchal and postmenopausal years
About 1–2% of patients in general gynecologic practice
It is currently considered to be an autoimmune condition, occurring in
genetically predisposed patients
Approximately 20 to 30 % of pts with LS have other autoimmune disorders, such as
Graves disease, Diabetes mellitus and SLE
21. Diagnosis
The characteristic clinical picture and histologic findings typically
confirm the diagnosis
1. Symptoms often worsen at night
Pruritus-the most common
LS with erosions or fissures:
Pain
Dysuria
Dyspareunia
2. Physical examination
Excoriations and vulvar skin thickening
White atrophic papules
The skin generally appears thinned and crinkled
Thickened white plaques, areas of erythema, or nodularity should prompt biopsy to exclude
preinvasive and malignant lesions
22. Vulvar LS
1. The skin is thin,shiny, pale,
and wrinkled (parchment-
like), with focal ecchymosis
2. There is loss of distinction
between the labia majora and
minora
23. Vulvar LS
Note the thin and pale vulvar skin, loss of
labia minora architecture, labia minora
fusion beneath the clitoris, and hourglass
distribution around vulva and anus
24. Treatment and surveillance
Curative therapies are not available for lichen sclerosus
Rx goals are symptom control and prevention of anatomic distortion
1. Vulvar Hygiene
2. Ultrapotent topical corticosteroids
3. Surgery
o Reserved for complicated cases
Introital stenosis
Symptomatic clitoral adhesions
Malignant transformation develops in 5% of pts
Surveillance
Every 6 to 12 months for life time
Persistently symptomatic, new, or changing lesions are biopsied
25. Treatment
1. Vulvar Hygiene
Avoid using gels, perfumed bath products, moisturizing wipes, and soaps, as they may contain irritants
Avoid douching
Use aqueous creams to clean the vulva and thoroughly rinse with tepid water
Avoid using a harsh washcloth to clean the vulva
After bathing, sparingly apply an emollient, such as plain petrolatum, to moist vulva epithelium
Dab the vulva gently to dry
Avoid wearing tight-fitting pants
Select white cotton underwear
Avoid washing undergarments in commercial washing detergents. Wash and rinse these items separately
and Consider using a multirinse process with cold water to remove any remaining detergent residue
Consider wearing skirts and no underwear at home and at night to avoid friction and aid drying
2. Ultrapotent topical corticosteroids
First-line therapy
3. Surgery
Reserved for complicated cases
Introital stenosis
Symptomatic clitoral adhesions
26. Lichen planus
Involves both cutaneous and mucosal surfaces
It affects 1-2 % of general population
Symptoms
Chronic vaginal discharge with intense vulvovaginal pruritus
Burning pain
Dyspareunia
Postcoital bleeding
Physical examination
Papules classically are brightly erythematous or violaceous,flat-topped, shiny
polygons
Vaginal erosions can produce adhesions and synechiae, which may lead to vaginal
obliteration
Diagnosis
Confirmed by biopsy
30. Contact dermatitis
This condition is common and affects all ages
It affects approximately 15–54% of women
It is classified as allergic or irritant contact dermatitis
ACD results from a T cell-mediated, delayed type hypersensitivity (DTH) reaction elicited by the
contact of the skin with the offending chemical in individuals who have been previously sensitized to
the same chemical
ICD is a localized inflammatory skin response that results from direct cytotoxic effect of irritants
The presentation of ICD and ACD is variable
Acute ICD develops within minutes to hours of the exposure, while those of ACD take 24–48 hours to
develop
The lesions of ICD tend to be well circumscribed, confined to the area of contact, more likely to be
painful, and less likely to develop vesicles and bullae, while those of ACD are more poorly
demarcated, more likely to be pruritic, and more likely to develop vesicles and bullae
Diagnosis
Patch test
To identify possible allergen
Culture
Biopsy
31. Treatment of vulvar contact dermatitis
1. Stop offending agents and/or
practices
2. Correct vulvar skin barrier
function
Sitz bath twice daily with plain water
Application of plain petrolatum
3. Treat any underlying infection
Oral antifungal therapy
Oral antibiotic administration
1. Reduce inflammation
Topical corticosteroids twice daily for
1-3 weeks
0.05% clobetasol propionate ointment
0.1% triamcinolone ointment
Systemic corticosteroids for severe
irritation
2. Break the itch-scratch cycle
Cool packs(avoid ice packs,which
may injure skin)
Plain,cold yogurt on a sanitary napkin
for 5-10 minutes
Consider an SSRI or an antihistamine
32. Vulvar contact dermatitis
Reaction to povidone-iodine
solution
Contact sites show symmetric
erythema and edema on the vulva,
inner thighs, and buttock
33. Atopic Dermatitis
It is predominantly a disease of childhood
With 85% of patients presenting before age 5 with severe pruritic eruption
70% of children show spontaneous remission before they reach adulthood
The disease first manifests in adulthood in only 2–8% of patients
The frequency of vulvar involvement is unknown
Scaly patches with fissuring are evident
Diagnosis
It is usually established by clinical findings and the appearance on the nongenital skin
There is no cure for the disease
Symptom control
Emollients
Topical corticosteroids
34.
35. Psoriasis
It is a chronic immune-mediated disease
Its prevalence is 3.2%
Involves the genitalia in 30–40% of patients
The median age of onset in women is 25 years
Symptoms of vulvar psoriasis
Itching
Burning
Pain
Physical examination
Classic form
Sharply demarcated erythematous papules and plaques covered with silvery scale
Treatments are none curative
Topical agents for mild disease
Immunosuppressive therapy
Methotrexate or Cyclosporine
Phototherapy
40. Epithelial inclusion cyst
Frequently develop on the vulva
More common on the labia majora and clitoris
They are benign lesions
Treatment
Rx is not usually necessary for asymptomatic small cysts
Surgical excision
If cyst is enlarging, symptomatic, or secondarily infected
42. Urethral Diverticulum
Classic symptoms associated with
urethral diverticula are known as the
"3D's"
1) Dysuria
2) Dyspareunia
3) Dribbling(Postvoid)
Women may also note recurrent
UTI, vaginal wall tenderness,
frequency, urgency, and chronic
pelvic or urethral pain.
44. Bartholin gland duct cyst and abscess
Bartholin gland
Secrete mucus to provide vaginal and vulvar lubrication
Each gland is approximately 0.5 cm in size and drains tiny drops of mucous into a
2.5 cm long duct
It open into the vulvar vestibule at about the 5 and 7 o’clock position, distal to the
hymenal ring
The most common large cyst of the vulva is a cystic dilation of an
obstructed Bartholin duct
Noninflamed cysts contain sterile, clear, mucinous fluid
The underlying cause for obstruction is often unclear
It may follow infection, trauma, mucus changes, or congenitally narrowed ducts
Bartholin duct cysts and abscesses are fairly common, with a lifetime risk
estimated to be 2%
46. Diagnosis
The diagnosis of both Bartholin cyst and abscesses are clinical
Cyst
It is typically painless, and may be asymptomatic
Most are detected during a routine pelvic examination or by the woman herself
Larger ones may cause discomfort, typically during sexual intercourse, sitting, or
ambulating
There is a soft, unilateral,round or ovoid ,painless mass in the posterior aspect of the
vaginal introitus, at the site of the gland
Abscesses
Typically present with severe pain and swelling and patients are unable to walk, sit, or
have sexual intercourse
There is a large, tender, soft, or fluctuant mass at the site of the gland
Abscess cultures
Biopsy
47. Biopsy…
Bartholin gland duct cysts and abscesses
Uncommon after menopause and should raise concern for possible neoplasia
Bartholin gland carcinoma is rare
The median age at diagnosis is 57 years
Cyst wall biopsy following cavity drainage to exclude rare Bartholin
gland carcinoma is considered for at-risk cases
Cysts in women older than 40 years, with solid components, fixation of the
cyst or abscess wall to surrounding tissue, or with multiple recurrences are
candidates
48. Microbiology
Bartholin gland abscesses are polymicrobial infections ???
According to recent studies fewer abscesses are polymicrobial
MRSA is increasing
The single most common pathogen is Escherichia coli
Bacteroides,peptostreptococcus species and staphylococcus faecalis are common
N.gonorrhoeae and C.trachomatis may also be identified
49. Management
No intervention is necessary for asymptomatic Bartholin cysts
Cysts that are disfiguring or symptomatic are treated
Procedures:
1. Incision and drainage
The mainstay of treatment is I & D with placement of a Word catheter, under local
anesthesia
2. Marsupialization
It refers to a procedure whereby a new ductal orifice is created
3. Bartholin gland excision is a definitive treatment
Antibiotic therapy
Trimethoprim-sulfamethoxazole
Amoxicillin-clavulanate + clindamycin
Cefixime + clindamycin
50. Bartholin gland duct incision and drainage
I & D with Word catheter placement
I & D is easy to perform
It is performed in an outpatient setting
It has high risk of recurrence →2 -18 %
51. The goal of Bartholin gland duct I and D is to
empty the cystic cavity and create a new
epithelialized tract(Word catheter ) for gland
drainage
A 1 cm incision is made using a scalpel with a
no. 11 blade to pierce the skin and underlying
cyst or abscess wall
The incision is placed on the cyst bulge,just
outside and parallel to the hymen at 5 or 7
o’clock and medial to the Hart line
A deflated Word catheter tip is placed into the
empty cyst cavity. A syringe is wed to inject 2
to 3 mL of sterile saline through the catheter
hub to inflate the balloon. Inflation should
reach a diameter sufficient to keep the catheter
from falling out of the incision
Word catheter in place
Abscess or cyst incision
Word catheter
52. Bartholin gland duct marsupialization
• A vertical or elliptical incision measuring
2 cm is made across the skin overlying
the cystic bulge using a scalpel no. 15
blade
• The incision is placed just outside and
parallel to the hymen at 5 or 7 o‘clock
and is positioned medial to Hart line
Skin incision.
53. Marsupialization
• It is performed in the operating room
• It takes longer time and is more invasive
• It has recurrence rates of 2 to 13 %
54. Wound closure
The edges of the cyst wall are sutured to adjacent
skin edges with interrupted sutures using 2-0 or 3-0
gauge delayed-absorbable sutures
Cyst wall sutured open
55. Bartholin gland duct excision
It is definitive procedure for treatment of both cysts and abscesses
Excision must be performed in an operating room
Candidates:
Symptomatic cysts which repeatedly recur and refill
Cysts with solid component
Raise concern for malignancy
Multilocular cysts
Excision carries a high risk of complications
Excessive bleeding
Hematoma formation
Cellulitis
Scarring
Disfigurement
Dyspareunia
57. Vulvar mucous cyst
• Most commonly seen in the vestibule or labia minora
• Excision is curative
58. Benign lesions of the urethra
• Urethral Prolapse
• Urethral Caruncles
• Urethral diverticulum
59. Urethral prolapse
It is the circular eversion of the urethral mucosa through the urethral
meatus with vascular congestion and possible strangulation
It may occur at any age
It is most common in premenarchal children and postmenopausal women
It may be related to relative lack of estrogen.
Physical examination
Large red polypoid mass covered with urethral mucosa with edematous
vascular submucosa, protruding from the urethra
Histologic examination
Cryosurgery is an effective method of treatment
61. Urethral Caruncles
Caruncles are fleshy, friable, sessile,
or polypoid masses that arise in the
posterior urethra near the meatus
Most patients are postmenopausal
Average age of 68 years
The etiology is unknown
Reduced estrogenisation of urethral
smooth muscle
Other possible factors include irritation,
trauma, and local congestion
Caruncles often are asymptomatic
Bleeding or dysuria
Superficial ulceration
Histologic examination
Distinguish a caruncle from urethral
prolapse
Treatment
Conservative approach-First line
Sitz-baths
Topical oestrogens
Topical anti-inflammatories or steroids
Surgery
Severe symptoms after failed
conservative management
Uncertain diagnosis
63. Vulvodynia
It is vulvar pain of at least three
months duration, without a clear
identifiable cause, which may have
potential associated factors
The prevalence is 3–7%
The median age of onset is 28 years
Treatments:
Symptom relief
Sitz baths
Topical emollients
Topical anesthetics
Topical and oral antidepressants
Oral neuropathic pain medications such as
gabapentin
Treatments…
Symptom relief….
Elimination of possible irritants and allergens
Adjunctive psychotherapy
Vestibulectomy
It is undertaken in some women with localized
vestibulodynia, and short-term follow-up
shows 60–85% of patients so treated
experience significant relief
64. Precursor lesions and malignant tumors of the vulva
Vulvar Intraepithelial Neoplasia (VIN)
Vulvar cancer
65. Vulvar Intraepithelial Neoplasia-VIN
HPV DNA has been found in up to 80% of VIN lesions
Classification:
VIN has three categories of squamous intraepithelial lesions (SIL):
1. Vulvar low-grade SIL (vulvar LSIL,flat condyloma, or HPV effect)
2. Vulvar high-grade SIL (vulvar HSIL, VIN usual type)
They are commonly associated with oncogenic HPV infection
o Particularly HPV 16
3. Differentiated VIN
It tend to be unifocal and are typically found in older, nonsmoking, postmenopausal women in
their sixth and seventh decade
66. VIN type Clinical presentation Risk factors
Vulvar LSIL
Formerly VIN 1
1. Flat lesions with basal atypia and koilocytic
changes such as condyloma
2. Self-limited ,not precancerous
HPV effect
Vulvar HSIL
Formerly VIN
ususal type(VIN
2,VIN 3,Vulvar CIS)
1. Multicentric and multifocal disease 1. Younger women
2. Oncogenic HPV infection
common
3. Cigarette smoking
4. Immunosuppression
Differentiated VIN 1. Unproven but likely precursor to most vulvar
SCC
2. Unicentric and unifocal disease .
3. A lesion may appear as an ulcer, warty papule,
or hyperkeratotic plaque
1. Older postmenopausal women
2. Oncogenic HPV infection
uncommon
3. Associated with vulvar
dermatoses such as lichen
sclerosus or LSC
Vulvar squamous intraepithelial lesions
67. Diagnosis
No screening strategies are available for vulvar HSIL detection
VIN may be asymptomatic
Symptoms
Itching
Burning
Pain
Clinially significant vulvar HSIL lesions are often visible without the
aid of special techniques
Vulvar biopsy
Suspicious focal vulvar lesions
Ulceration, surrounding induration, or inguinal adenopathy raises suspicion for invasive
cancer
70. Vulvoscopy
It is microscopic examination of the vulva
Selection of the best location for biopsy is usually aided by magnification with
a colposcope
Apply 3-5% acetic acid soaked gauze pad for 5 minutes
o Acetic acid accentuates surface topography and may reveal acetowhite lesions not seen grossly
The most abnormal-appearing areas are biopsied
Careful documentation, mapping of vulvar biopsy sites, and photographs can aid future
management
71. Management
Objectives
Excluding and preventing invasive
disease
Preserving vulvar appearance and
function
Improving patient symptoms
Vulvar LSIL
Self-limited and is not treated unless
symptomatic
Vulvar HSIL
87% of untreated high-grade VIN
patients progresses to vulvar cancer,
whereas only 3.8% of treated patients
progresses to invasive cancer
All vulvar HSIL must be treated
1. Laser ablation
It requires full epithelial thickness cellular
destruction
2. Wide local excision (WLE)
With a gross surgical margin of 0.5 to 1 cm
of normal tissue is preferred for large
lesions
3. Cavitational ultrasonic surgical
aspiration (CUSA)
4. Topical therapy
It can be considered if there is no concern
for invasive cancer
72. Prognosis and prevention
Recurrence rates up to 50% are common
Multifocal disease
Immunocompromised status
Prevention
HPV vaccination
Smoking cessation and improving compromised immune status
Treat vulvar dermatosis
Indefinite surveillance for multifocal LAGT disease is recommended
73. Vulvar cancer
It constitutes only 6 % of all gynecologic malignancies
Vulvar squamous neoplasia arise predominantly along the Hart line
Approximately 90% of vulvar cancers are SCC
Malignant melanoma is the second most common
Vulvar cancer may involve any of the external vulvar structures
Mons pubis
Labia majora and minora
Clitoris
Vestibule
Vestibular bulbs
Bartholin glands
Paraurethral glands
Urethral and vaginal openings
74. Risk factors
Age
The average age at diagnosis is 65
years
HPV infection
50 to 75 % of invasive vulvar
cancers are associated with high
risk HPV serotype
HPV become a stronger
contributor when combined with
other cofactors
Smoking-35 fold greater risk
HSV infection
Vulvar intraepithelial neoplasia
(VIN)
Approximately 4% of women with
a history of high grade VIN
subsequently develop vulvar
cancer
Chronic immunosuppression
HIV
Transplant patients
Lichen sclerosus
Affected keratinocytes show a
proliferative phenotype
75. Diagnosis
History and physical
examination
Women commonly present with
pruritus and visible lesion
They may also have pain, bleeding
,ulceration and inguinal mass
Evaluate the entire vulva and
perineal skin systematically
Measure the primary tumor
Evaluate cancer extension into other
genitourinary compartments, the anal
canal, the bony pelvis and inguinal
lymph nodes
Histopathology
Specimen taken with a keyes punch
should be approximately 4mm thick to
include the surface epithelial lesion and
the underlying stroma
This permits evaluation for depth of
invasion
Imaging
Abdomen, chest and pelvis
CT
MRI
PET
76. Vulvar biopsy steps
1. A Keyes punch biopsy is placed against
the biopsy site and gentle downward
pressure is exerted as the punch is
rotated
2. A core biopsy is created that extends
through the epidermis and into the
dermis
3. The tip of a fine needle is used to
elevate the core, while fine scissors
incise its base
77. Management
Surgery
Surgery is often an integral part of vulvar cancer treatment
Wide local excision
Vulvectomy
Inguinofemoral lymphadenectomy
Neoadjuvant chemoradiation
Surveillance
80. Imperforate hymen…
Failure of the inferior end of the
vaginal plate to canalize
Incidence:
1 in 1000 to 2000 females
Clinical features
1. In neonatal period
o Hydro/mucocolpos
Most cases are asymptomatic
Bulging translucent yellow-gray mass
It resolves as estrogen levels decline
2. Adolescents after menarche
o Hematocolpos,hematometra and
hematosalpinx
The vaginal canal greatly distends, and the
cervix may dilate with cyclic menstruation
Cyclic pain, amenorrhea, abdominal pain,
and difficulty with urination or defecation
The trapped menstrual blood creates a
bluish bulge at the introitus
Treatment
Many advocate repair either in infancy or after
thelarche, but before menarche
o Presence of estrogen improves tissue healing
o Avoids formation of hematocolpometra
Hymenectomy
o Cruciate incision is made anteroposteriorly from
10 to 4 and from 2 to 8 o'clock positions
o The hymenal leaflet are excised and then over
sewn with interrupted stitches using 3-0 or 4-0
vicryl or chromic suture
o The vagina is copiously irrigated with sterile
saline solution
o Local wound care includes twice-daily sitz baths
o Assess patency of introitus and healing 1-2 weeks
after surgery
81. The hymenal leaflet are excised and then over sewn with interrupted
stitches using 3-0 or 4-0 vicryl or chromic suture
82. Hymenectomy
The indication for hymenectomy may
include complain of amenorrhea, pain,
abdominal mass, and urinary and
defecation dysfunction
Hymen Incision
To avoid injury to the urethra anteriorly
and to the rectum posteriorly, the surgeon
avoids creating pure vertical and horizontal
incisions. Instead, a cruciate incision is
made anteroposteriorly from 10 to
4 and from 2 to 8 o'clock into the hymeneal
membrane
Hymenal leaflet trimming
83. Transverse vaginal septum
It results when there is failure of fusion and/or
canalization of the urogenital sinus and mullerian
ducts
Incidence
1 in 70,000 females
It can develop at any level within the vagina
Approximately 46 % are found in the upper vagina, 35 to
40 % in the middle portion, and 15 to 20% in the lower
vagina
84. Transverse vaginal septum…
Diagnosis:
Patients usually present with symptoms similar to those of imperforate hymen
Symptoms and signs
o Primary amenorrhea and pelvic pain
o Abdominal or pelvic mass
o Foreshortened vagina and inability to identify the cervix
Imaging
o Sonography or MRI confirms the diagnosis
o MRI
It is most helpful prior to surgery to determine the septal thickness and depth
It also help to differentiate a high vaginal septum from cervical agenesis
85. Management
Antibiotic prophylaxis is usually
administered
Vaginal septum excision is best
performed in a post pubertal
adolescent or young adult
Thin septum
Excision followed by end-to end
anastomosis
Thick septum
Excision followed by skin or buccal
mucosal grafts
Intercourse is delayed for 6 weeks
post surgery
Mold advice
Soft stent for 7 days
Plastic dilator for 12 weeks
Intercourse at least twice each week
86. Vaginal septum excision
• Enema bowel preparation aids rectal decompression to
permit greater vaginal traction for visualization
• The septum is then incised transversely at its center to
avoid laceration of the urethra, bladder, or rectum.
• A finger is placed through the transverse incision and
is centered cephalad to delineate the upper vaginal wall
and the circumferential margins of the septum
• Once the septum's perimeter and thickness is defined,
the initial transverse incision is extended laterally to
the vaginal
wall margins. The septum is widely excised
circumferentially along its base to minimize
postoperative stricture
• Others surgeons prefer to create cruciate incisions
similar to those with hymenectomy
• The four wedges are then trimmed close to the vaginal
wall
If the septum was thin, a simple
circumferential ring of interrupted
stitches is constructed using 2-0
gauge delayed-absorbable suture
to reapproximate vaginal mucosal
edges
87. Atrophic vaginitis
Physiologic events in
postmenopausal women
Reflect estrogen deprivation
o Atrophy of the squamous epithelium of the vagina
A minor trauma may facilitate a transition from simple
atrophy to atrophic vaginitis
o A loss of glycogen and an increase in pH
o A change in the vaginal flora
Reduction in the lactobacilli
Symptoms
Many patients are asymptomatic
There may be minor vaginal bleeding,
pruritus, dysuria, or dyspareunia
Physical examination
A pale-appearing mucosa, with
petechiae and loss of rugal folds
Treatment
There usually is a good response to estrogen replacement
Antibiotic therapy rarely is necessary
88. Vaginal agenesis
Lack of the lower portion of the vagina
with otherwise normal pubertal maturation
and external genitalia
The urogenital sinus fails to contribute its
expected caudal portion of the vagina
As a result, the lower portion of the vagina,
usually one-fifth to one-third of the total length, is
replaced by 2 to 3 cm of fibrous tissue
It does not often become apparent until
menarche
89. Vaginal Agenesis…
Symptoms
Cyclic pelvic pain due to
hematocolpos or hematometra
Physical examination
The hymeneal ring is normal, and no
bulging membrane is seen
Proximal to the ring, only a vaginal
dimple or small pouch is found
A rectoabdominal examination
confirms midline organs
Imaging
Sonography or MRI will display
upper reproductive tract organs
MRI is the most accurate diagnostic tool
o Length of the atresia
o Amount of upper vaginal dilation
o Presence of a cervix
A cervix in such cases distinguishes vaginal atresia
from mullerian agenesis
Treatment follows that for mullerian
agenesis
90. Vaginal cysts and neoplasms
Squamous inclusion cyst
Cysts of the vagina are relatively
uncommon
Gartner’s duct cysts
Mullerian cyst
Benign neoplasms
Squamous papilloma
Condyloma acuminatum
Müllerian papilloma
Leiomyoma
Rhabdomyoma
Malignant neoplasms
Vaginal intraepithelial neoplasia
Vaginal cancer
Primary vaginal cancer is rare,
constituting only 1%–2% of all female
genital tract malignancies and only 10% of
all vaginal malignant neoplasms
91. Gartner duct cyst
It is derived from remnants of the mesonephric
(Wolffian) ducts
They are typically asymptomatic
Symptoms
Dyspareunia
Vaginal pain, and
Difficulty inserting tampons
Physical examination
Reveals a tense cyst that is palpable or seen to bulge
beneath the vaginal wall
They are thin walled, translucent, and contain clear fluid
They are most often located along the anterolateral
wall of the vagina
Observation is reasonable in most cases
Marsupialization or excision may be appropriate
for symptomatic Gartner duct cysts
93. Endocervical polyp
These lesions represent overgrowths of benign
endocervical
stroma covered by mucinous columnar epithelium
They typically appear as single, red, smooth, elongated
masses extending
from the endocervical canal
It is found more frequently in multiparas
They are usually asymptomatic, but they can cause
intermenstrual or postcoital bleeding or symptomatic
vaginal discharge
Many of them are identified by visual inspection during
pelvic examination
They are typically benign, and premalignant or malignant
transformation develops in less than 1 %
Most recommend removal and histologic evaluation of all
polypoid lesions
94. Nabothian Cyst
• Nabothian cysts are the most common type of
cyst of the cervix and develop within the transformation zone secondary to
squamous metaplasia covering over and obstructing endocervical
glands. Grossly, these lesions appear as yellow
white cysts that are frequently multiple and can
measure up to 1.5 cm in diameter. Microscopically, they are lined by a
somewhat flattened,
single layer of mucin-producing endocervical
epithelium (Fig. 50). In some cases, squamous
metaplasia of the lining epithelium occurs. The
lining epithelium is almost always at least
focally positive with mucicarimine stains allowing these lesions to be
distinguished from
95. Cervical Stenosis
This narrowing of the cervical canal or opening may be congenital or acquired.
Diagnosis is based on symptoms and physical findings
Symptoms of stenosis in menstruating women include dysmenorrhea,
amenorrhea and infertility
Postmenopausal women are usually asymptomatic until fluid,
exudates, or blood accumulates behind the obstruction
If the obstruction is complete, a soft, enlarged uterus from trapped
intracavitary fluid is sometimes palpable
An inability to introduce a dilator into the endocervical canal is generally considered diagnostic
Cervical stenosis is relived by introduction of dilators
Preprocedural misoprostol may aid by softening the cervix
In postmenopausal women, pretreatment for several weeks with vaginal estrogen cream may
also assist dilation.
103. Introduction
• The introduction of Pap test has reduced the incidence and mortality
rate from invasive cervical cancer by more than 70 percent
104. Terminology and histology of cervical
intraepithelial neoplasia
LAST: lower anogenital squamous
terminology; LSIL: low-grade squamous
intraepithelial lesions; HSIL: high-grade
squamous intraepithelial lesions; CIN:
cervical intraepithelial neoplasia.
* CIN 2 that is p16-positive is classified
as HSIL. CIN 2 that is p16-negative is
classified as LSIL.
Squamous neoplasia of the vagina, vulva,
perianal,and anal squamous epithelia (VaIN,
VIN, PAIN, and AIN, respectively) are graded
similarly with the caveat that VIN 1 is no longer
recognized
105. Anatomic considerations
External Genitalia
o Micropapillomatosis labialis
Minute epithelial projections on the inner labia minora
Uniform in size and shape and arise singly from
their base attachments
Often shows spontaneous regression, and
treatment is not indicated
o HPV lesions
Multifocal and asymmetric, and to have
multiple papillations arising from a single base
106. SCJ everts outward on to ectocervix SCJ regresses into endocervical canal
Adolescence Squamous metaplasia
Pregnancy Menopause
COC use Prolonged lactation
Cervix
Squamocolumnar Junction
• The original squamocolumnar junction (SCJ) marks the terminal site of the upward
migration of squamous epithelium during embryonic development
• When visible on the ectocervix, the SCJ is a pink, smooth squamous epithelium
juxtaposed against the red, velvety columnar epithelium surrounding the external
cervical os
• The location of the SCJ varies with age and hormonal status
Long term pop use
107. Squamous Metaplasia
the normal replacement of columnar by squamous epithelium on the cervix
Squamous metaplasia is most active during adolescence and pregnancy
This normal process creates a progressively
widening band of metaplastic and maturing
squamous epithelium, termed the transformation
zone ( Z), between the congenital (original)
columnar epithelium and the squamous
epithelium
108. Transformation Zone and Cervical Neoplasia
• The transformation zone consists of the band of squamous
metaplasia lying between the original SCJ and new (current) SCJ
• Nearly all cervical neoplasia, both squamous and columnar,
develops within the Z, usually adjacent to the new or current
SCJ
109. Human papillomavirus
• HPV primarily infects squamous or metaplastic epithelial cells.
• Intact virus is shed during normal desquamation of superficial
squames.
• Late genes are not strongly expressed in high-grade neoplastic lesions
• Completion of the viral life cycle takes place only within an intact,
fully differentiating squamous epithelium.
• HPV is a nonlytic virus, and therefore infectiousness depends on
normal desquamation of infected epithelial cells.
110.
111. L1 and L2 are two “late” genes of the human
papillomavirus (HPV) genome. These genes encode
proteins
responsible for which of the following?
a. Capsid construction
b. Regulatory functions
c. DNA synthesis and replication
d. Conformational changes aiding entry into the host
cell

Genital HPV Infection=It is the most common STD(USA)
113.
114. Clinically, human papillomavirus (HPV) types are
classified as high risk (HR) or low risk (LR) based
upon their oncogenic potential. Which two HR HPV
types together account for approximately 70 percent
of cervical cancers worldwide?
a. 6 and 11
b. 11 and 45
c. 16 and 18
d. 18 and 31
115. Transmission
Risk factors
the number of sexual partners
Both life time and recent
early coitarche
Cervical HR HPV infection generally requires penetrative intercourse
All women who are sexually active should undergo cervical cancer
screening regardless of sexual orientation
Infection with HPV, predominantly HR types, is very common
soon after initiation of sexual activity
116. Transmission…
Genital warts that develop in children after infancy(1-3years)
o Possibilities are:
Sexual abuse
Nonsexual contact
Autoinoculation
Fomite transfer
Congenital HPV infection from vertical transmission beyond transient skin
colonization is rare
Infection is not linked to maternal genital warts or route of delivery
Indication for cesarean delivery :Large genital wart that may obstruct
delivery or Avulse and bleed
117. Infection Outcomes
Most infections are subclinical.
Spontaneous resolution is the most common outcome.
Neoplasia is the least common manifestation of HPV
infection, developing as the result of persistent infection
with integration of HPV DNA
The natural history of genital HPV infection varies between
individuals and over time
Latent infection refers to that in which cells are infected, but
HPV remains quiescent
Productive infections are characterized by viral life-cycle
completion and plentiful production of infectious viral particles
Subclinical infections may be indirectly identified as low-
grade cytologic, colposcopic, or histologic abnormalities
118. HPV Infection Diagnosis
• HPV infection is suspected based on clinical lesions or results
of cytology, histology, and colposcopy, all of which are subjective and often inaccurate.
• Moreover, serology is unreliable and cannot distinguish past from current infection
• culture of HPV is not feasible
• Thus, diagnosis is confirmed only by the direct detection of HPV nucleic acids by
methods that include in situ hybridization, nucleic acid amplication testing (NAA ),
polymerase chain reaction (PCR),or others
• Tests are not indicated or useful for routine STD screening
• Appropriate clinical uses or HR HPV testing include: cotesting with cervical cytology
screening in women aged 30 years or older, triage or surveillance of certain
abnormal cytology results and untreated CIN, and posttreatment surveillance
• One HR HPV test (cobas HPV test) was recently FDA approved as a stand-alone screening
test for cervical cancer for women 25 years of age and older
119. Infection Treatment
• The indications to treat HPV-related LG disease are symptomatic warts,
high-grade neoplasia, or invasive cancer.
• Treatment of cervical LSIL (HPV changes or CIN 1) is not
necessary and is considered only after observation for at least
2 years.
• Mechanical removal or destruction, topical immunomodulators, and
chemical or thermal coagulation can be used
• Examination of a male partner does not benefit a female partner either by
in influencing reinfection or by altering the clinical course or treatment
outcome or genital warts for LG neoplasia
120. Infection Prevention
Behavior
• Sexual abstinence, delaying coitarche, and limiting the number
of sexual partners are logical strategies to avoid genital HPV
infection and its adverse effects.
Vaccines
• Prophylactic vaccines elicit type-specific humoral antibody production
that prevents new HPV infection by blocking its entry into host cells
• They do not prevent transient HPV positivity or resolve preexistent
infection
• HPV vaccines have the potential to prevent malignancies at least six body
sites that include cervix, vulva, vagina, penis, anal canal, and oropharynx
121. Vaccines
• There are three HPV vaccines (FDA approved)
• All three vaccines contain adjuvants that boost the
immune response to vaccine antigens.
• Testing for HPV is not recommended prior to vaccination
• ACIP target group:Girls aged 11 to 12 years (as early as age 9
years)
Vaccine type HPV type covered Remark % of Cx prevented

122. HPV vaccine
• They are administered in three intramuscular doses during a 6-month period.
• Specifically, the second dose is given 1 to 2 months after the first dose, and the
third dose is given 6 months after the first dose.
• Immune compromised women are candidates to receive the vaccine
• All three vaccines show nearly 100-percent efficacy in preventing incident
infection and high-grade cervical neoplasia from HPV types included in the
vaccines
• HPV4 and HPV9 are approved for genital wart prevention in both males and
females
• HPV vaccines are highly immunogenic with maintenance of protection for at least
5 to 8 years after vaccination
• No evidence supports the need for later booster dosing
• Because HPV vaccines prevent most, but not all, HPV related cervical cancers,
cervical cancer screening should continue per current guidelines
123. • Catch-up vaccination is also recommended for
all 13- to 26-year-old persons
• ACOG recommends shared decision-making with persons aged 27 to 45
years who
have not previously received the HPV vaccine and are at risk of
acquiring HPV.
• IfHPV vaccination is initiated before age
15 years, only 2 doses are needed. This is because the vaccine is
more immunogenic at an earlier age. The second dose is given
6 to 12 months following the first
124. • HPVvaccines have excellent safety profiles, are well-tolerated,
and can be administered along with other recommended vaccinations. Injection-
site erythema, pain, and sweling are common. These can increase in severity
following subsequent doses
but are usually mild to moderate. HPV vaccination is avoided
during pregnancy, but pregnancy testing is not recommended
prior to administration (American College of Obstetricians and
Gynecologists, 2017). If inadvertently given during pregnancy,
no action is needed. Vaccination can be given during lactation.
Immunocompromised persons are candidates to receive the
vaccine and show high seroconversion rates despite concerns
for a blunted immune response. 9vHPV should be given with
caution to persons who experienced an allergic reaction to a
prior dose, have an allergy to yeast, or have had a recent febrile
illness
125. CIN
• CIN is most strongly related to
persistent genital hrHPV
infection and aging
• Inadequate screening is a strong
cervical neoplasia risk factor.
126. Natural History
• Preinvasive lesions can
spontaneously regress, remain
stable, or
progress
• The risk of progression to
invasive cancer rises with
CIN severity
127. CIN diagnosis
• Cervical Cytology
• HPV testing
• Current Cervical Cancer Screening
Guidelines
• Colposcopy
• Biopsy
128. Which of the following is true regarding the clinical
performance of the Pap test?
a. Higher sensitivity than specificity
b. Higher specificity than sensitivity
c. Equally low sensitivity and specificity
d. Equally high sensitivity and specificity
129. Cervical cytology
oThe preventive power of Pap testing lies in
regular serial screening
oThe Papanicolaou (Pap) test
Specificity→98%
Sensitivity→45-65%
Sampling of the transformation zone at the SCJ adds substantial sensitivity of
the Pap test
130. How can we optimize the pap test?
oSchedule to avoid menstruation
oPatients should abstain from vaginal intercourse, douching, vaginal tampon
use, and intravaginal medicinal or contraceptive creams
for a minimum of 24 to 48 hours before tested
oTreatment of cervicitis or vaginitis prior to Pap testing is optimal
oAdd the following clinical information to pathology requisition forms
LNMP
Pregnancy or menopausal status
Exogenous hormone use
Abnormal bleeding, and
Prior abnormal Pap test findings
IUCD
131. Cytology Collection
• Three types of plastic devices are commonly used to sample
the cervix: the spatula, broom, and endocervical brush (cytobrush)
• Wooden collection
devices and cotton swabs are no longer recommended due to
their inferior collection and release of cells
132. Devices
1. Plastic spatula
Predominantly samples the ectocervix
distal endocervical canal
It firmly scrapes the cervical surface while completing
at least one full rotation
2. Endocervlcal brush
samples the endocervical canal
To minimize bleeding, the brush
is used after the ectoccrvix has been sampled and is
rotated only one-quarter to one-half turn
3. Plastic broom
Samples
both endo- and ectocervical epithelium simultaneously
Five rotations in the same direction are recommended.
Broom devices are favored for
liquid-based Pap testing.
133. HPV Testing
Indications
• cervical cancer screening
• triage of lesser cytologic abnormalities to later repeat
testing or immediate colposcopy
• surveillance after colposcopy,
or surveillance after treatment
134. Co-testing
o Pap test plus HPV test
o Raises the sensitivity of a single screening test for high-grade
neoplasia and leads to earlier detection and management of
HSIL
o It offers a nearly 100-percent negative predictive value for high-grade neoplasia.
o Result can be:
Both negative
• Repeat after 5 years
Cytology positive but HPV negative
• ???
Cytology negative but HPV positive
• Occur in 10% of the cases
• co-testing is repeated 12 months later
• A reflex test specifically for HPVs 16 and 18
If positive immediate colposcopy recommended
135. Primary HPV Testing
oHPV testing alone is approximately twice as sensitive (>90%) as
a single Pap test and leads to earlier detection of high-grade
disease.
oTo counter the lower specificity:
Genotyping is part of primary HPV screening
for cervical disease and allows the triage of women who test
positive for HPV 16 or 18 to immediate colposcopy
If positive for non HPV 16 and 18→Reflex cytology is proposed
• Colposcopy for abnormal cytology
oApproved by FDA for primary cervical cancer screening in women aged ≥25
years
136. Appropriate clinical uses for high-risk human
papillomavirus (HPV) testing include which of the
following?
a. Surveillance after treatment of cervical neoplasia
b. Cotesting (cytology plus HPV testing) as screening
for women 30 years or older
c. Triage or surveillance of certain abnormal cervical
cytology results or untreated cervical intraepithelial
neoplasia (CIN)
d. All o the above
137. Current cervical cancer screening guidelines
The choice of screening strategy should be a shared decision by the provider and patient.
139. Screening Discontinuation
• Screening may be stopped at age 65 years in those at average risk for
cervical cancer and who have undergone adequate
screening, regardless of past or current sexual history.
• Adequate
screening is defined as three consecutive, negative cytology
results or two consecutive, negative co-test results in the prior
10 years, with the most recent result occurring within the past
5 years
140. If all Pap tests to date have been negative and performed
at recommended intervals, cervical cancer
screening discontinuation would be acceptable for
which fo the following women?
a. A 42-year-old woman with prior hysterectomy for
leiomyomas
b. A 72-year-old woman in good health with one
prior sexual partner and one new sexual partner
or 6 months
c. A 55-year-old woman with metastatic breast cancer
refusing further therapeutic cancer interventions
d. All o the above are reasonable candidates or
discontinuation o cervical cancer screening.
141. Post hysterectomy
• All guidelines
recommend against Pap test screening for women who have
undergone total hysterectomy (cervix removed) for a benign disease indication
and who lack a prior high-grade CIN or
cervical cancer diagnosis.
• Women who have undergone supracervical hysterectomy
should continue routine screening.
• The American College of Obstetricians
and Gynecologists (2018b) recommends Pap testing of the vaginal cuff every 3
years for 20 years after initial posttreatrment
surveillance, which is traditionally a schedule of three Pap tests
in the first 2 years posthysterectomy
142. Immunocompromised Patients
• With HIV infection, screening should commence within 1
year of sexual activity onset and no later than age 21 years.
• Women aged 21 to 29 years should receive Pap testing at
the time of HIV diagnosis
• If an initial Pap test result is negative, testing should be repeated 6 or
12 months later and then continued every 12 months. After
three consecutive, negative Pap test results, the interval of Pap
testing can be extended to 3 years. For women aged ≥30 years,
cytology screening can be followed as just described, or cotesting every 3 years can begin. This co-
testing interval is shorter
than for immune competent women. Cervical cancer screening
is continued indefinitely even in those aged 65 years or older
who have been adequately screened.
• After hysterectomy for
benign disease, vaginal cuff cytology is not recommended.
143. A 55-year-old patient undergoes a conization procedure
for cervical intraepithelial neoplasia (CIN 3)/
carcinoma in situ (CIS). Appropriate postexcision
surveillance over the subsequent 2 to 3 years reveals
no recurrence. Which of the following screening
schedules is most appropriate for her beyond this
posttreatment surveillance?
a. Discontinue screening
b. Annual screening until age 75 then may
discontinue
c. Routine screening until age 65 then may
discontinue
d. Routine screening for at least 20 years even if
screening extends beyond age 65
145. The Bethesda System
• Cervical cytology reporting is
standardized by the Bethesda
System nomenclature.
146. Epithelial Cell Abnormality Management
• A cytology report interprets a screening test and does not provide a
final diagnosis.
147. Atypical Squamous Cells of Undetermined
Significance ASC -US
Positive Negative
Reflex HPV testing
Colposcopy
Cotest every 3 years
No HPV test
Repeat cytology in 1 year
Risk of CIN 2 or 3 is 5-10%
Risk of cancer is 1-2%
Rate of HPV positivity is app 50%
149. Atypical Squamous Cells, Cannot Exclude HSIL
• Colposcopy is indicated regardless of age or HPV test
result
• If SCJ is not visualized ,do diagnostic excision
150. High-Grade Squamous lntraepithelial Lesion.
• Colposcopic evaluation is warranted regardless of age or HPV status
• If SCJ not visualized ,do diagnostic excision
• Altenatively, immediate excision is
acceptable in some nonpregnant patients depending on other
factors such as age and concerns regarding future pregnancy
151. Glandular Cell Abnormalities
• Initial evaluation of a cytologic glandular cell
abnormality includes colposcopy and endocervical sampling,
regardless of HPV status.
• It also includes endometrial sampling in patients aged ≥35 years or in
younger women with risk factors for endometrial disease
• Reflex HPV testing is not recommended for the triage of
glandular cytologic abnormalities for fear that a negative result
will dissuade appropriate evaluation.
152. Carcinoma.
• Cytology results suspicious for squamous cell
carcinoma or adenocarcinoma are rare and carry the highest
risk of invasive cancer.
• If initial evaluation fails to reveal invasive cancer, a diagnostic excision
procedure is indicated
153. Colposcopy
• The colposcope provides a bright light
source and variable magnification
through an optical lens system or high
resolution digital imaging.
• Sensitivity estimates range
between 50 and 80 percent
• Colposcopic examination is optimally
timed to avoid
menses but is not delayed if there is a
visible cervical lesion
or abnormal bleeding, or if the patient is
unlikely to return.
• Solutions used during colposcopy are
normal saline, 3-
to 5-percent acetic acid, and Lugol iodine
154. Solutions used
• To begin, normal saline helps remove discharge and cervical
mucus and allows initial assessment of vascular patterns and
surface contours. A green (red-free) light filter adds contrast to
aid vascular pattern visualization (Fig. 29-9).
Acetic acid 3- to 5-percent solution is mucolytic and exerts its
whitening effects, termed acetowhitening, presumably by reversibly
denaturing cellular proteins. This causes neoplastic areas to
appear denser compared with the normal surrounding epithelium, and
lesions assume varying hues of transient whiteness. Lugol iodine solution
stains mature, glycogen-rich squamous
epithelium a dark purple-brown color in reproductive-aged
women with normal serum estrogen levels. Due to incomplete
maturation, dysplastic epithelium has a lower glycogen content, fails to
fully stain, and appears yellow
155. Lesion Grading
• With colposcopy, normal squamous
epithelium of the cervix
appears featureless, pale-pink and
smooth. Blood vessels lie
below this layer and therefore are not
visible or are seen as a
fine capillary network
• The mucin-secreting columnar
epithelium appears red due to its
thinness and close proximity of
underlying blood vessels. Its villous
appearance derives from
epithelial peaks and crypts
156. Biopsy
Ectocervical Biopsy
oAll acetowhite lesions and other
abnormalities are biopsied using
cervical biopsy forceps under direct
colposcopic visualization
Recomendations encourage biopsy
of all acctowhite areas; two to four
biopsies of abnormalities
are recommended for optimal
sensitivity
Endocervical Sampling
oEndocervical curettage is
performed by introducing an
endocervical curette 1 to 2 cm into
the cervical canal
oIndications
The SCJ is not fully visualized.
The SCJ is fully visualized, but no
lesion is identified.
Initial evaluation of ASC-H, HSIL,
AGC, or AIS cytology test results
Tissue from endocervical sampling is always sent
separately from ectocervical biopsies for histologic
evaluation
157. Pregnancy
oPregnancy does not alter the natural history of cervical disease
oPregnancy is an opportunity to screen patients aged ≥21
years as indicated
oWhen colposcopy is indicated, its primary goal during
pregnancy is to exclude invasive cancer
oColposcopy and biopsy
are safe and accurate during pregnancy
oEndocervical and endometrial sampling are never performed
during pregnancy to avoid amnionic membrane rupture, infection, or other
harm to the pregnancy
oCIN is reevaluated postpanum since lesion grade frequently changes after
delivery and puerperal remodeling
158. CERVICAL INTRAEPITHELIAL
NEOPLASIA MANAGEMENT
• CIN management may be surveillance or treatment
• CIN severity, colposcopic findings, age,
and reproductive plans play key roles in cervical disease management.
159. CIN 1
oHistologic LSIL (HPV changes or CIN 1)
oCIN 1 is no longer treated immediately
periodic cytology or co-testing.
oTreatment is acceptable only if CIN 1 persists for more than 2 years
Ablation
• Criteria require that the SCJ and all lesions are fully seen during colposcopy and that the
endocervical sampling lacks HSIL (CIN 2/3) or ungraded CIN
Excision
• If the above criteria are not met and treatment is indicated, excision is recommended
and ablation is unacceptable
160. HSIL: CIN 2 and CIN 3
• Generally, treatment is recommended for CIN 2 or CIN 3
because of the significant malignant potential and
the efficacy of treatment to eradicate precancers.
• Treatment modalities include either ablation or excision of the entire TZ
• Recurrent or persist HSIL after treatment
is managed with repeat excision, not ablation
• Hysterectomy may be indicated if repeat excision is needed but not anatomically feasible
or if high-grade CIN recurs or persists and invasive cancer has
been thoroughly excluded
• Hysterectomy as
primary therapy is unacceptable
• For young women, particularly of low parity, with CIN 2 or HSIL (CIN 2/3, not otherwise
specified) surveillance or treatment is acceptable, if the SCJ and all lesions are fully seen
during colposcopy
161. Adenocarcinoma in Situ
• Exclusion of coexistent invasive cancer and
removal of all affected tissue are primary goals
• AIS can
be multifocal, lie deep within endocervical crypts, and extend
high into the endocervical canal
• Thus, diagnostic excision is recommended to exclude invasive cancer with maximum certainty
• cold-knife conization is favored over loop electrosurgical excision procedure (LEEP) to get an intact specimen
with the most interpretable
margins
• Ifthe excised specimen
shows no invasive cancer, hysterectomy is recommended in
women who have completed childbearing
162. Postcolposcopy Surveillance
without Treatment
• When colposcopy following abnormal screening tests fails to
diagnose a high-grade precancer or there is spontaneous regression ofhigh-
grade CIN in younger women, further surveillance
is indicated.
• Surveillance involves repeat cytology, HPV testing, or colposcopy alone or
in combination at specific intervals
depending on the original abnormal cytology result, patient
age, and current guidelines.
• Exceptions are AGC, favor neoplasia and AIS Pap test results. These are
always followed by
excision unless invasive cancer is diagnosed during initial colposcopic
examination and biopsy
163. CERVICAL INTRAEPITHELIAL
NEOPLASIA TREATMENT
• Current treatment of CIN is limited to ablation or excision
procedures targeting the entire TZ
• Thus, individual cervical
lesions are not treated. Any treatment ideally should reach a
depth of 5 to 7 mm from the surface to treat CIN adequately. Surgical
treatments have an approximate 90-percent
success rate
164. Ablation
• This involves physical destruction of tissue and is generally
effective for noninvasive ectocervical disease
• Before ablation,
glandular neoplasia or invasive cancer are excluded with the
greatest possible certainty.
• Ablation should
not be used after previous therapy, after glandular cytologic
abnormalities, or for AIS
• The most commonly used ablative treatment modalities are
cryosurgery and carbon dioxide (C02) laser
165. Excision
• Excision procedures are favored when
the risk of invasive cancer is significant
• Excision is also indicated for
persistence
or recurrence ofhigh-grade CIN after
treatment
• Excisional modalities include LEEP,
also known as LLETZ
(large loop excision of the
transformation zone}; cold-knife
conization (CKC); and laser conization.
166.
167. Surveillance after Treatment or Regression
• Post-treatment surveillance with cytology, HPV testing, and/or
colposcopy is required to confirm treatment success
• After excision, surveillance will be influenced by margin status.
• After treatment for high-grade cervical dysplasia or
invasive cancer, screening continues for at least 20 years, even ifscreening
extends beyond age 65.
• If an excision margin or endocervical curettage performed
immediatdy after an excision is positive for HSIL {CIN 2 or
CIN 3), repeat excision may be indicated. Repeat excision is
indicated for special circumstances such as AIS or microinvasive carcinoma
at the excision margins.
168. Hysterectomy
• Hysterectomy is unacceptable as primary therapy for CIN
• However, it may be considered when treating
recurrent high-grade cervical disease if childbearing has been
completed or if a repeat cervical excision is strongly indicated
but not technically feasible.
• Hysterectomy is the preferred
treatment of AIS, if future fertility is not desired and excision
has excluded invasive cancer.
Even with negative cervical margins, hysterectomy performed for CIN
2 or worse is not completely protective.
169. Cervical Cancer
oCervical cancer is the most common gynecologic cancer in
women worldwide
oWomen have 1 in 132 lifetime risk of developing this cancer
oThe median age at diagnosis of cervical cancer is 50 years
oHPV is the primary etiologic infectious agent associated
with cervical cancer
99.7 percent of cervical cancers are associated with an oncogenic HPV subtype
170. Risk factors
o Lack of regular cervical screening
o HPV infection
o Lower education attainment,older
age,neighborhood poverty
Related to lower rate of cervical
screening
o Cigarette smoking
2-3 fold increased risk for HSIL or invasive
cancer
Reduced clearance of hr HPV infection
Modify viral oncoprotein expression
o Parity
7-four fold
1 or 2-two fold
oLong term COC use
o HPV positive +COC user-4 fold
o Relative risk decrease after 10 years of
cessation
oMultiple sexual partner
> 6 life time sexual partner
oEarly coitarche
Before 20 years
oImmunosupression
Cervical ca is AIDS defining illness
Transplant recipients on azathioprine
171. PATHOPHYSIOLOGY
o Tumorigenesis
Unlike low-risk serotypes,
oncogenic HPV serotypes can integrate
into human DNA
Amplification of viral replication and
subsequent transformation of normal
cells into tumor cells may follow
E7 oncoprotein binds to the
retinoblastoma (Rb) tumor suppressor
protein, whereas E6 binds to the p53
tumor suppressor protein
• In both instances, binding leads to
degradation of these suppressor proteins.
• The E6 effect of p53 degradation is well
studied and linked with the proliferation
and immortalization of cervical cells
172. Spectrum of cervical dysplasia
• A. This initial point shows the cell at risk
due to active HPV
infection. The HPV genome (blue ring)
exists as a plasmid, separate from the
host DNA.
• B. The clinically relevant preinvasive
lesion, cervical intraepithelial neoplasia 3
(CIN 3) or carcinoma in situ (CIS), is an
intermediate stage in cervical cancer
development. The HPV genome has
become integrated into the host DNA,
resulting in increased proliferative ability.
• C. Interactive effects between
environmental insults, host immunity, and
somatic cell genomic variations lead to
invasive cervical cancer
173. Tumor Spread
Lymphatic Spread
o The cervix has a rich network of
lymphatics, which follow
the course of the uterine artery
o The pattern of tumor spread typically
follows cervical lymphatic drainage
o In contrast, lymphatic channels from
the posterior cervix course through the
rectal pillars and the uterosacral
ligaments to the rectal lymph nodes.
Lymph Node Groups
Paracervical and
parametrial lymph node
Obtrator lymph node
Paraaortic lymph node
Internal,external and
common iliac lymph nodes
174. Lymphatic drainage of the cervix
The parametrial
lymph nodes are removed
during radical hysterectomy.
Pelvic and
paraaortic nodes also may be
removed by lymphadenectomy
176. Local and Distant Tumor Extension
• With extension through the parametria to the pelvic sidewall, ureteral
blockage frequently develops, resulting in hydronephrosis
• Additionally the bladder may be invaded by direct tumor extension
through the vesicouterine ligaments (bladder
pillars). The rectum is invaded less often because it is anatomically
separated from cervix by the posterior cul-de-sac. Distant
metastasis results from hematogenous dissemination, and the
lungs, ovaries, liver, and bone are the most frequently affected.
177. HISTOLOGIC TYPES
o Squamous cell carcinomas represent 70% of all cervical
cancer, and adenocarcinomas account for 25% of cervical
cancers.
o The other cell types are rare
o SCC-arise from the ectocervix
o Adenocarcinoma-arise from the endocervical
mucus-producing columnar cells.
o Mucinous adenocarcinomas are the most common
o Endometeroidadenocarcinomas are the second most
frequently identified and display glands resembling those of
the endometrium
o Women with Peutz-Jegher syndrome are at higher risk of
developing adenoma malignum(Minimal deviation)
contain a greater number of glands positioned at a deeper level
than normal endocervical glands.
178. Prognosis Comparison
• Women with adenocarcinomas
have worse overall survival rates
at every stage compared with
those with squamous cell
carcinoma(FIGO)
Other Tumor Types
oThe following has poor prognosis
Neuroendocrine tumors of the
cervix are highly aggressive
Cervical sarcoma
• leiomyosarcomas
• stromal sarcomas
Melanomas
179. DIAGNOSIS
Symptoms
• Some women diagnosed with this
cancer are asymptomatic.
In others, early-stage cervical cancer
may create a watery,
blood-tinged vaginal discharge.
Intermittent vaginal bleeding that
follows coitus or douching also can be
noted. As
a malignancy enlarges, bleeding
typically intensifies, and
occasionally, a woman presents with
uncontrolled hemorrhage from a
tumor bed
180. Physical examination
o Most have normal general physical
examination
o External genitalia and vaginal
examination
o Inspect anogenital area
o Speculum examination
o Bimanual examination
The proximal posterior vaginal wall is
most commonly involved
o Rectovaginal examination
Thick hard irregular rectovaginal septum
oDigital rectal examination
Appreciate the parametrial,uterosacral
and pelvic side wall involvement
Thick irregular firm and less mobile
A fixed mass indicates that tumor has
poorly extended to the pelvic side walls
• Lower extremity edema
• Low back pain radiating to legs
• Hydronephrosis
oLymphatic tumor spread to
supraclavicular and inguinal
lymphadenopathy
oHematuria or Vesicovaginal or
rectovaginal fistula
181. Papanicolaou Test and Cervical Biopsy
oHistologic evaluation of cervical biopsy is the primary tool to
diagnose cervical cancer
oPap testing alone for evaluation of a suspicious lesion is discouraged
Due to low single test sensitivity(53-80%)
• Thus, the preventive power of Pap testing lies in regular serial screening
Take biopsy for diagnosis
• Biopsies are taken from the tumor periphery and include underlying stroma
oCervical punch biopsies or conization specimens are the most accurate for
allowing assessment of cervical cancer invasion
182. STAGING
o Historically, cervical cancer has been
staged clinically.
o The current staging system now
incorporates radiologic and surgical
evaluation
Lymph node metastases worsen patient
prognosis and may be identified with
imaging.
o early-stage disease refers to FIGO stages
I through IIA.
o The term advanced-stage disease
describes stages IIB and higher
o Accurate evaluation is critical to
appropriate treatment planning
183.
184.
185. Which of the following tests is NOT used for staging
cervical cancer per the International Federation of
Gynecology and Obstetrics (FIGO)?
a. Cystoscopy
b. Chest radiograph
c. Intravenous pyelogram
d. Computed tomography scan
187. MRI
• Measures tumor size, delineates cervical
tumor boundaries, and identifies surrounding bladder, rectal, or
parametrial invasion.
• Offers superior contrast resolution at soft tissue interface
• Less accurate for diagnosing microscopic or deep cervical stromal
invasion or identifying minimal parametrial extension
• For primary cervical cancer, MR imaging is superior to CT
for determining carcinoma size, local tumor extension, and
lymph node involvement
188. Computed Tomography
• for the assessment of nodal involvement and distant metastatic
disease
• CT can also aid detection of ureteral obstruction
• CT is not accurate for assessing subtle parametrial invasion or deep
cervical stromal invasion
• CT is also limited by its inability to detect small volume metastatic
involvement in normal-size lymph nodes.
189. Positron Emission Tomography
• Enable an imaging of functional processes within the body
• FDG-PET is superior to CT or MR imaging for lymph node
metastasis identification
• However, PET is insensitive for lymphatic metastasis <5 mm
190. LYMPH NODE DISSECTION
• It offers accurate metastasis detection and may
modify a patient's primary treatment strategy
• Potential candidates include patients with positive or suspected
positive pelvic nodes undergoing chemoradiation treatment
• During lymphadenectomy, most experts recommend lymph
node dissection in the common iliac and paraaortic region
and resection of macroscopic lymph nodes
191. PROGNOSIS
• FIGO stage is the most
significant prognostic factor
• Lymph node involvement is an
important prognostic feature
• In addition, the number of nodal
metastases is predictive
• In general, microscopic nodal
involvement has a better
prognosis than macroscopic
nodal disease
192. EARLY-STAGE PRIMARY
DISEASE TREATMENT
• Early stage disease includes stage I to IIA
• Stage IA is a microinvasive cervical cancer that carries a minor risk of
lymph node involvement and excellent prognosis following treatment.
193. Stage IA1
oRisk of nodal metastasis-1.5%
oOption of treatment
Cervical conization
Total extrafascial hysterectomy (type I hysterectomy) is preferred
for women who have completed childbearing
oWhen LVSI present in Stage IA1,the risk of lymph node metastasis is app 5%
Modified radical hysterectomy (type II hysterectomy) and pelvic lymphadenectomy.
Radical trachelectomy with pelvic lymph node dissection can be considered in those
patients desiring fertility preservation
194. What is the most appropriate treatment for a 30-year old
woman who has stage IA1 adenocarcinoma of
the cervix, negative lymphovascular space invasion
(LVSI), and strongly desires future fertility?
a. trachelectomy
b. Cold-knife conization
c. Extra fascial hysterectomy
d. Modifed ( type II) radical hysterectomy
195. Stage IA2
o These cancers have a 7-percent risk of lymph node metastasis and carry a >4-
percent risk of disease recurrence
o Radical (or modified radical) hysterectomy and pevic
lymphadenectomy is recommended.
o For fertility preservation, stage IA2 squamous cervical lesions
may be treated with radical trachelectomy and lymphadenectomy.
o A nonabsorbable cerclage may be placed concurrently
with radical trachelectomy to improve cervical competence
during pregnancy
o Preoperative MR imaging to evaluate the
parametria and/or CT scan to evaluate extracervical disease is
recommended in these cases.
196. IA1 and IA2
• Alternatively, patients with stage IAl and IA2 cervical cancer can be
treated with intracavitary brachytherapy alone with
excellent results
• Potential
candidates for vaginal brachytherapy include women who are
elderly or who are not surgical candidates due to comorbid
medical disease
197.
198. Which of the following statements about radical
trachelectomy is FALSE?
a. Cesarean delivery is required if pregnancy
achieved.
b. Preterm birth rates are increased after radical
trachelectomy.
c. At least 1 cm of endocervix must remain attached
to the uterus.
d. If the shave margin is positive, hysterectomy is
completed
199.
200. Stage 1B to IIA
• Stage IB to IIA cancers do not extend into the parametria and
thus can be managed with either surgery or chemoradiation
• In general, radical hysterectomy for stage IB through IIA
tumors is usually selected for premenopausal women who wish
to preserve ovarian function and for women who have concerns
about altered sexual functioning following radiotherapy.
• Age and weight are not contraindications to surgery.
• Surgery is contraindicated in patients with severe cardiac or
pulmonary disease
201. Weighing Surgical and
Radiotherapy Complications
Early-stage cervical cancer radical surgery
• Ureteral stricture
• Vaginal fistulas, bladder
dysfunction,constipation, wound
breakdown, lymphocyst, and
lymphedema
• VTE
Radiation therapy
• altered sexual function secondary to a
shortened vagina
• Dyspareunia
• psychologic factors
• vaginal stenosis
• Late urinary and bowel complications
such as fistula formation,
enteritis, proctitis, and bowel
obstruction
202. Positive Pelvic Lymph Nodes
• Approximately 15 percent of
patients with clinical stage I
through IIA cervical cancers will
have positive pelvic nodes.
oRisk factors for lymph node
involvement include
Histologic grade
Depth of invasion
Stromal invasion
Parametrial extension
LVSI
203. Recurrence Risk
For women who have completed radical surgery for early-
stage cervical cancer, the GOG has defined risk factors to
help identify women for tumor recurrence
204. ADVANCED-STAGE PRIMARY
DISEASE TREATMENT
• Radiation Therapy
• Both external beam pelvic radiation
and brachytherapy are typically delivered
• During evaluation, if paraaortic nodal
metastases are found, extended field radiation can be added to
treat these affected lymph nodes
205. Chemoradiation
• Chemotherapy given concurrently
with radiation therapy significantly
improves overall and disease free
survival rates in women with
cervical cancer
• It is now recommended that
cisplatin based chemotherapy
should
be considered in women
undergoing radiation for cervical
cancer
208. SURVEILLANCE
Following Radiotherapy
o In general, patients are seen at 3month
intervals for 2 years,
then every 6 months until 5 years have
passed from treatment,
and then annually
o Vaginal dilator or have vaginal intercourse
o Pelvic examination and/or radiologic
scanning
shrinkage of the mass
o Rectovaginal examination
Nodularity in the ligaments and parametria
o Manual nodal survey
neck, supraclavicular, axillary, and inguinal
lymph nodes
o A cervical or vaginal cuff Pap test also is
collected annually for 20 years after
treatment completion
o Colposcopy ,biopsy ,CT or CT/PET as
needed
209. SURVEILLANCE …
• Following Surgery
• After a radical hysterectomy, 80
percent of recurrences are
detected within the subsequent 2
years
• During patient surveillance, an
abnormal pelvic mass or abnormal
pelvic examination finding typically
prompts CT scanning of the abdomen
and pelvis.
• Clinical findings include cervical or
vaginal lesion, rectovaginal nodularity,
pain radiating down the posterior
thigh,
or new-onset lower extremity edema.
Pelvic recurrences after
radical hysterectomy, if diagnosed
early, can be treated with
radiation therapy
• The same schedule of visits and Pap
tests as
outlined above for surveillance
following radiotherapy is then
recommended
210. SURVEILLANCE …
• Hormone Therapy
• Cervical cancer is not estrogen-dependent and thus hormone
therapy is not contraindicated to treat menopausal symptoms
• Either systemic
or vaginal forms of estrogen are suitable.
211. SECONDARY DISEASE
• This is defined as either
persistent or recurrent cancer
• usually palliative Rx
• pelvic radiation if not received
before
• Metastatic cervical cancer is not
curable
• Pelvic Exenteration for
Secondary Disease
• Radiotherapy or Chemotherapy
for Secondary Disease
chemoradiation for radiotherapy
naive pts
212. PALLIATIVE CARE
• Pain management forms the basis of palliation
• Many will require narcotics
• Treat constipation
• Home hospice
213. MANAGEMENT DURING PREGNANCY
• A greater proportion of patients have stage I disease
• A Pap test is recommended for all pregnant patients older than
21 at the initial prenatal visit.
• Additionally, clinically suspicious lesions are directly biopsied
• If Pap test results reveal HSIL,
adenocarcinoma in situ (AIS), or suspected malignancy, colposcopy is performed
and biopsies are obtained.
• endocervical curettage is excluded to prevent amnionic sac rupture
• IfPap testing indicates malignant cells and colposcopy-directed
biopsy fails to confirm malignancy, diagnostic conization may be
necessary
214. Stages I and II Cancer in Pregnancy
• Women with positive nodes may elect to
be
treated with definitive treatment, rather
than delay.
• Given the
outcomes, a planned treatment delay is
generally acceptable for
women who are 20 or more weeks'
gestational age at diagnosis
• For patients with stage IA2
through IIAI, a cesarean section via a
classical uterine incision
may be performed at term, followed
immediately by radical
hysterectomy and lymph node dissection.
Notably, a classical
cesarean incision minimizes the risk of
cutting through tumor
in the lower uterine segment, which can
cause serious blood
loss and result in tumor spread
• (stage IAl) may deliver vaginally and he
reevaluated
6 weeks postpartwn
215. Advanced Cervical Cancer in Pregnancy
• Women with advanced cervical cancer diagnosed prior to fetal
viability are offered primary chemoradiation.
• Spontaneous
abortion of the fetus tends to follow whole-pelvic radiation
therapy.
• For women who decline pregnancy termination, systemic chemotherapy can be administered.
Cisplatin with vincristine or paclitaxel can be administered in pregnancy.
• If cancer is
diagnosed after fetal viability is reached and a delay until fetal
pulmonary maturity is elected, then a classical cesarean delivery is performed. Chemoradiation is
administered after uterine
involution.
• For patients with advanced disease and treatment
delay, pregnancy may impair prognosis. A woman who elects
to delay treatment, to provide quantifiable benefit to her fetus,
will need to accept an undefined risk of disease progression.
216. A 29-year-old primigravida at 10 weeks’ gestation
has a Pap test result of adenocarcinoma in situ (AIS).
Colposcopy and biopsies performed are concerning for
invasive adenocarcinoma. What is the best next step?
a. Pregnancy termination
b. Conization at 6 weeks’ postpartum
c. Cesarean radical hysterectomy at term
d. Conization early in the second trimester
