TRANSCRIPT
Fibroma
Mesenchymal Odontogenic
tumors • Benign mesenchymal tumor
(Benign tumor of fibrous connective tissue)
• The most common benign soft tissue neoplasm in the oral cavity
Peripheral
Central
Clinically•Well defined
•Normal color of oral mucosa or slightly paler•Sessile or pedunculated •Smooth , non ulcerated surface unless traumatized
TONGUE Gingiva
Buccal mucosa Palate
SITE
Soft or firm in consistency depending on its cellular or fibrous contents
firm soft
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
Case
A 40 years old female complain of painless slowly growing mass in the left side of hard palate in 4,5 region since 2years
No history of any traumatic injury, pain or pus drainage
Size : 0.5 x 0.5 cm. On palpation : slightly pedunculated – non tender – didn’t blanch on pressure –rubbery in consistency
Intraoral examination
Radiographic Examination
Upper left 4,5
Mild horizontal bone loss with canine, first and second premolars. No root resorption or tooth displacement. Bone around the outer limit of the lesion is normal
Other investigations
•Hemoglobin •Total WBCS count•Clotting time
Normal
Aspiration wasn’t done bec. It is solid
Phase-1 therapyNon surgical treatment
Complete stoppage of tobacco chewing. Keep good oral hygiene
Operative procedureExcision of the lesion under L.A with adrenalinMedications were prescribedPatient recall for evaluation
