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)
