1

The most common tumor of the oral cavity; probably not a true neoplasm; reactive lesion, secondary to trauma or chronic irritation

Fibroma

2

F>M, 4th-6th decade; commonly located along the bite line of the buccal mucosa; sessile, smooth-surfaced pink nodule

fibroma

3

variant of fibroma that feature both clinically and histologically unique features; unassociated with trauma or irritation

giant cell fibroma

4

F>M, first 3 decades; most occur on gingiva, followed by tongue; sessile, often papillary nodule; features large, stellate-shaped or multinucleated fibroblasts

Giant cell fibroma

5

reactive lesion that occurs secondary to irritation from an ill-fitting denture

epulis fissuratum

6

any tumor of the gingiva or alveolar mucosa

epulis

7

F>M, middle aged and older; single or multiple folds of firm, fibrous tissue located in the alveolar vestibule (usually anterior)

epulis fissuratum

8

lesions can achieve large size; may be ulcerated; fibroepithelial polyp- pedunculated lesion of palate beneath maxillary denture

epulis fissuratum

9

reactive process of the palate underneath a maxillary denture; associated with: ill-fitting denture, poor hygiene, wearing denture 24 hr/day; superimposed candidiasis

inflammatory papillary hyperplasia

10

variable involvement of the hard palate; aymptomatic, erythematous lesion with a pebbly surface; had been seen on edentulous mandibular ridge or on epulis

inflammatory papillary hyperplasia

11

may see pseudoepitheliomatous hyperplasia

inflammatory papillary hyperplasia

12

common non-neoplastic proliferation of granulation tissue; not a true granuloma; response to local irritation or trauma; F>M, children and young adults; common during pregnancy

pyogenic granuloma

13

rapidly growing, smooth or lobulated ulcerated mass; easily bleeds; any mucosal surface with most involving the gingiva

pyogenic granuloma

14

relatively common reactive lesion of the gingiva; histologically identical to the central giant cell granuloma

peripheral giant cell granuloma

15

F>M, 5th and 6th decades; bluish-purple lesion, exclusively on the gingiva or alveolar ridge; radiographic- may cause "cupping" resorption (saucerization)

peripheral giant cell granuloma

16

relatively common reactive lesion, probably arising from periodontal ligament; this lesion is unrelated to the central ossifying fibroma; teenagers and young adults; maxilla>mandible; exclusively on the gingiva; frequently ulcerated

peripheral ossifying fibroma

17

mineralization, consisting of bone, cementum-like, or dystrophic calcifications; ulcerated surface; 16% recurrence rate

peripheral ossifying fibroma

18

benign tumor of fat; although rare in the oral/maxillofacial area, the lipoma is the most common mesenchymal neoplasm; unrelated to metabolism/body fat

lipoma

19

F>M; soft nodule, most commonly involving the buccal mucosa; normal or yellow in color; well circumscribed, lobular arrangement of mature adipose tissue

lipoma

20

reactive proliferation of neural tissue; not necessarily a true neoplasm; secondary to disruption of Schwann cell tube

Traumatic neuroma

21

F>M, middle-aged adults; smooth surfaced, submucosal nodule; commonly involve the mental foramen area; may be symptomatic

traumatic neuroma

22

benign neural tumor of schwann cell origin; uncommon, but often involve the head and neck

schwannoma

23

oral tumors most commonly involve the tongue; may arise within bone, causing an expansile, unilocular radiolucency

schwannoma

24

Schwannoma: Antoni _ tissue: Spindle-shaped schwann cells palisaded around central acellular areas (Verocay bodies)

A

25

Schwannoma: Antoni _ tissue: Randomly arranged spindle cells against a myxomatous background; Ancient schwannoma

B

26

the most common peripheral nerve neoplasm; tumor cells are a mixture of Schwann cells and fibroblasts

neurofibroma

27

typically solitary, involving the tongue or buccal mucosa; may occur in bone; multiple lesions associated with neurofibromatosis

neurofibroma

28

circumscribed proliferation of spindle-shaped (comma-shaped) cells against a background of delicate collagen fibers; variable numbers of mast cells

neurofibroma

29

Relatively common autosomal dominant syndrome (50% new mutations) with variable expressivity

Neurofibromatosis (Von Recklinghausen's Disease of Skin)

30

Type _ neurofibromatosis: bilateral acoustic neuroma (schwannoma of auditory nerve)
