Q

Peripheral Ossifying Fibroma Overview;

A

tumor exclusively on the gingiva (10% of all reactive gingival swelling)

reare reports on edentulous mucosa

arises from PDL or periosteum

24
Q

What are clinical features of peripheral ossifying firbroma?

A

exclusively on the gingiva

anterior to molar and maxillary

well demarcated sessile nodules

frim

pink and red if ulcerated

25
Q

Describe the histology of peripheral ossifying fibroma.

A

cellular fibrous connective tissue with calcified bone or osteoid; some cementum like tissue

ulcerated surface

vascularity not prominent

26
Q

What is the treatment for peripheral ossifying fibroma?

reactive in nature

originates from pdl or periosteum

29
Q

What are the clinical features of peripheral giant cell granuloma?

A

occurs exclusively on the gingiva, edentulous and dentat

mainly anterior to molars

sessile = red or red/blue lesion

sometimes resorbs underlying bone in uniform “saucer-like” appearance

30

“cuffing” effect with slight bone resorption as described

not common

31

A

fibrovascular stroma with numberous multinucleated gian cells and hemosiderin pigment

32
Q

What is the treatment for peripheral giant cell granuloma?

A

complete excision including curetage of underlying bone

remove local irritants
prognosis good

33
Q

Fibroma (traumatic or irritation)

A

most common soft tissue tumor in te oral cavity

difficult clinically and histologically to differentiate between benign and hyperplasia

34

A

30-50 with no sex predilection

37
Q

Describe the histology of fibroma.

excision

43

Leiomyoma Characteristics

A

a binign neoplasm of smooth muscle origin

more common in the GI, uterus and skin

oral cavity = originates from vascular smooth muscle

angiomyoma = 75% of oral leiomyomas

A

flat or elevated and purplish-red

blanch on pressure (unless thrombus)

present centrally (aspirate before surgery)

52

A

head and neck

oral cavity: tongue, buccal mucosa, and lips

53
Q

Whos is commonly effected by hemangioma?

A

equally in sexes (some say more in females)

children mainly (even at birth) on the lips (no treatment except to improve scar cosmeics)

54

Describe the histology of hemangiomas?

A

proliferation of vascular spaces lined by endothelial cells

56
