Clinically•Well defined

•Normal color of oral mucosa or slightly paler•Sessile or pedunculated •Smooth , non ulcerated surface unless traumatized

TONGUE Gingiva

HISTOPATHOLOGY stretched St.sq.epitheliumflattening of the rete pegs

HISTOLOGIC APPEARANCE OF FIBROMA

THE SURFACE OF THE LESION IS COVERED BY A LAYER OF STRATIFIED SQUAMOUS EPITHELIUM WHICH FREQUENTLY APPEARS STRETCHED AND SHOWS FLATTENING OF THE RETE PEGS.

Hyperplastic fibrous C.T

stretched St.sq.epitheliumflattening of the rete pegs

AREAS OF CALCIFICATION OR EVEN OSSIFICATION MAY BE DETECTED IN SOME FIBROMAS ESPECIALLY THOSE OF GINGIVA AND HARD PALATE

• WHEN THE LESION IS TRAUMATIZED OR IRRITATED

Inflammatory cells,

vasodilatation and inflammatory

edema • MAY DEVELOP FROM PYOGENIC GRANULOMA

•PRESENCE OF FIBROMAS AFFECTS NORMAL FUNCTIONING AND ESTHETICS MAY CAUSE SOCIAL AND EMOTIONAL PROBLEMS

•Conservative surgical excision •Recurrence is rare

Treatment

Surgical removal
