17. Varix
&
other vascular malformations
It is a type of acquired vascular malformation .

lingual tongue surface .
Syndrome : lingual varices .
18. Pyogenic Granuloma
Etiology
Injury or stimulus (EX : calculus ) .
Hormonal changes .
This well lead to :
Modified gingival reparative mechanism .
Prolifration of CT rich with capillaries .

Etiology:
.Unusual hyperplastic CT response to injury
.Leads to : reparative process containing multinucleated giant cells
Clinical features:

Origin : PDL
. Shape : red blue , broad based mass and may ulcerate
Age : any age
Sex : female > male
Radiographically : result in erosion of cortical bone
23. Scarlet Fever
Systemic bacterial infection can lead to capillary damage .
Clinically :
Pharyngitis , Tonsillitis, fever, lymphadenpathy and
headache
Red face

papilla (strawberry tongue)
After the white coat is lost (raspberry tongue)
