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
Describe the histology of peripheral ossifying fibroma.
cellular fibrous connective tissue with calcified bone or osteoid; some cementum like tissue ulcerated surface vascularity not prominent
26
What is the treatment for peripheral ossifying fibroma?
excision deep to the PDL extract tooth if it recurs >2 times (16-20%)
27
What age and gender is peripheral ossifying fibroma more commonly found in?
10-19 years of age females (2/3)
28
Peripheral Giant Cell Granuloma Overview:
reactive in nature originates from pdl or periosteum
29
What are the clinical features of peripheral giant cell granuloma?
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
What are the radiographic features of peripheral giant cell granuloma
"cuffing" effect with slight bone resorption as described not common
31
Describe the histology of peripheral giant cell granuloma
fibrovascular stroma with numberous multinucleated gian cells and hemosiderin pigment
32
What is the treatment for peripheral giant cell granuloma?
complete excision including curetage of underlying bone remove local irritants prognosis good
33
Fibroma (traumatic or irritation)
most common soft tissue tumor in te oral cavity difficult clinically and histologically to differentiate between benign and hyperplasia
34
What is the most common cause of fibroma?
cheek chewing
35
What are the clinical features of fibroma?
most common on the buccal mucosa and lip occurs anywhere presents as dome shaped, smooth, pink or white nodule
36
Who is most commonly effected by fibroma?
30-50 with no sex predilection
37
Describe the histology of fibroma.
fibrous connective tissue nodule lined by surface mucosa (keratotic and maybe thick)
38
What are the treatment options for fibroma?
Surgical removal remove irritant (habits)
39
Lipoma Overview
Benign neoplasm of adipose origin tissue uncommon orally
40
What are the clinical features of lipoma?
Floor of the mouth, tongue, and buccal mucosa are most common lipomatous nodule on buccal mucosa = fat herniation
41
What is the appearance of a lipoma?
single, smooth surfaced, soft, lobulated, painless yellowis, sessile nodule lined by thin epithelium visible blood vessel soft (mistaken for a cyst)
42
what is the treatment for lipoma?
excision
43
Who is more commonly affected by lipoma's?
Oral: adults with equal sex predilection skin: females 2x more common
44
Leiomyoma Characteristics
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
45
What are the clinical feature of leiomyoma?
Slow growing painless pedunculated, smooth surfaced, normal color or slighlty buish nodule central leiomyoma vry rare
46
What are the common locations of leiomyoma?
posterior tongue, palate, cheeks and lips
47
Who is commonly effected by leiomyoma?
>30 years old Predominantly male
48
Describe the histopathology of leiomyoma.
well-circumscribed nodule made up of smooth muscle cells
49
Treatment options for leiomyoma.
simple & conservative excision
50
Hemangioma characteristics.
benign proliferation of blood vessels (most are hemartomas)
51
What are the clinical features of hemangioma?
flat or elevated and purplish-red blanch on pressure (unless thrombus) present centrally (aspirate before surgery)
52
Where does hemangioma commonly occur?
head and neck oral cavity: tongue, buccal mucosa, and lips
53
Whos is commonly effected by hemangioma?
equally in sexes (some say more in females) children mainly (even at birth) on the lips (no treatment except to improve scar cosmeics)
54
What are hemangiomas commonly associate with?
Sturg-Weber Hereditary Hemorrhagic Telangiectasia
55
Describe the histology of hemangiomas?
proliferation of vascular spaces lined by endothelial cells
56
Treatment options for hemangioma?
depends on size and relationship to other anatomical sructure, blood flow injecting sclerosing agents, surgical debulking; complete excision
