2. Cystitis cystica and glandularis is a rare
proliferative disease of mucus-producing
glands within the mucosa and submucosa of
the bladder epithelium.
It is characterized by foci of transitional cells
that underwent glandular metaplasia.
7. The prevalence of symptomatic cystitis glandularis with a
gross lesion in the US is 0.9–1.9%.¹
Autopsy series that looked for von Brunn nests, cystitis
cystica and cystitis glandularis in asymptomatic
people, found that 50–100% of samples have these
histologic changes with no gross lesion²
Which led to the belief that cystitis cystica and glandularis
may be an incidental histologic finding rather than a
precursor to bladder cancer.

8. Chronic bladder inflammation caused by:
Stones
Bladder outflow obstruction
Long-term indwelling catheter i.e spinal injury
Pelvic Lipomatosis:
Rare proliferative disorder that causes increase
deposition of fat around the bladder, rectum and
prostate.
Cystitis glandularis is found in 75% of those patients¹
No clear risk factors.

10. Venous and lymphatic stasis due to perivesical fat
compression and chronic inflammation.
Leads to mucosal edema and proliferation of blood
vessels within the stroma.
The damaged epithelium sloughs off and regenerates
with hyperplasia and subsequent glandular
metaplasia.

Frequency
Dysuria
Urgency
Bacteruria
Gross hematuria
Chronic UTI
They may complain of voiding mucus
Less frequently: ureteral obstruction and
subsequently hydronephrosis.

13. A gross appearance looks like cobblestone pattern.
The bladder neck and trigone are the areas most
frequently involved.
Followed by the lateral walls and the dome of the
bladder.

16. The first step is to treat the source of chronic bladder
irritation if it is present i.e. treat UTI and stones, replace
indwelling catheters with CIC.
Transurethral resection of bladder lesions.
Intravesical steroids injection.
Nephrostomy tubes may be initially necessary for severe
ureteral obstruction before definitive therapy.
Bladder augmentation and cystectomy have been
described in severe intractable cases who fail initial
therapy and progressed into bladder contracture and renal
failure.
19. The first reported study implicating Cystitis Cystica and
Glandularis in the development of adenocarcinoma was
published in 1950.¹
In 1980, first report of bladder adenocarcinoma in a
patient with Cystitis Cystica and Glandularis associated
with pelvic lipomatosis.²

20. Since then, sporadic case reports have associated Cystitis
Cystica and Glandularis with bladder cancer.
Around 16 case reports were published.
10 of them, the conclusions were based only on the
synchronous presence of cancer with glandular metaplasia
in the specimen.

Bladder Carcinoma. UROLOGY :–
21. In 2008 a study was published from Cleveland Clinic. They
studied 88 patients with cystitis cystica and glandilaris and
15 patients with intestinal metaplasia who underwent
interval follow up cystoscopies for a mean period of 4.4
years.
1 patient of the cystitis group developed bladder TCC, and
this occurred 3 months after the initial biopsy. To be noted
that this patient had a past history of upper tract TCC.
None of the intestinal metaplasia group had subsequent
bladder cancer.

Bladder Carcinoma. UROLOGY :–
22. This case reveals the continued challenge to understand this
rare disease and its clinical importance as a precursor to cancer.
It is clearly indicated that cystitis glandularis and intestinal
metaplasia can be identified coincidentally with bladder cancer.
However, the long-term outcomes have not supported the role of
these lesions as preneoplastic.
Larger series of patients with cystitis glandularis and intestinal
metaplasia are needed to delineate the association between
these lesions and bladder cancer.
Until then, interval cystoscopy might be of value and for an
indefinite time.¹

Notas del editor
To understand this disorder well, we need to know where it comes from
One of the accepted theory is the metaplastic theory. It starts with formation of Von Brunn’s nests which are proliferation of transitional cell foci
Central degeneration of these foci leads to formation of what is called cystitis cystica
More degeneration in the centerwith metaplasia of the epithelial cells into a cuboidal/columnar phenotype produces cystitis glandularis
Presence of goblet cells is consistent with intestinal metaplasiaAnother theory says that cystitis glandularis originate in the fetal life from displaced intestinal epithelium during separation of the rectum fromthe urogenital sinus, some note that it is inadequate because it’s present in renal pelvis.
Why I’m saying symptomatic cystitis glandularis.
Long-term indwelling catheter especially in patients with spinal injury.
The most common presentation:What are the symptoms
This is an IVP of an AIDS patient with severe cystitis cystica and glandularis with bilateral obstruction.
The big question here is it a benign lesion or a precursor to bladder tumor should we follow it up?

Which might be linked to his history of upper tract disease rather than cystitis glandularis
