Flashcards in Head and Neck Deck (46):
1

most common ulcer of the mouth; 20% of population; recurrent; painful

recurrent aphthous ulcers (canker sore)

2

acute gingivostomatitis

HSV primary infection

3

best recognized form of candidal infection; adherent white plaque; caused by broad spectrum antibiotics/immunosuppression; mild burning sensation/unpleasant taste

acute pseudomembranous candidiasis

4

red, macule, burning sensation, tongue as the most common site, diffuse atrophy of dorsal tongue papillae; maybe caused by broad-spectrum antibiotic therapy

erythematous candidiasis

5

erythematous candidiasis; referred to as "median rhomboid glossitis" in the past; well-defined area of redness, mid-posterior dorsal tongue; asymptomatic

central papillary atrophy

6

least common from of candidiasis; anterior buccal mucosa; resemble leukoplakia; complete resolution of the lesion after antifungal therapy

chronic hyperplastic candidiasis

7

red, fissured lesions of corners of mouth; loss of vertical dimension as one of predisposing factors; usually related to candidiasis but other bacterial microflora may be admixed

angular cheilitis

8

a benign reactive lesion rather than neoplastic origin; focal fibrous hyperplasia; occurs anywhere that persistant chronic tissue irritation occurs

irritation fibroma

9

a common, fast growing, reactive lesion; surface ulcerated; bleeds easily; 75% of cases in gingiva

oral pyogenic granuloma

10

a white patch or plaque that cannot be scrapped off and cannot be characterized clinically or pathologically as any other disease; premalignant lesion (most common of oral cavity)

leukoplakia

11

a white lesion induced by chronic mechanical irritation; essentially a "callous"

frictional keratosis

12

a frictional keratosis induced by chewing habit

morsicatio buccarum

13

keratotic change of the palatal mucosa in heavy smokers

nicotine stomatitis

14

necrotic epithelium can be peeled away in contrast to frictional keratosis

chemical burn

15

a chronic inflammatory mucocutaneous disease; white, keratotic lesions; "Wickham" striae;

Lichen Planus

16

can affect any site, but worrisome sites are tongue, floor of the mouth, and soft palate; homogenous white or speckled appearance

oral leukoplakia

17

important predisposing factors to leukoplakia

tobacco; alcohol; immunosuppression; HPV

18

red patch that cannot be clinically or pathologically diagnosed as any other condition; greater presence of dysplasia than leukoplakia

erythroplakia

19

well-demarcated velvety, red plaque; floor of mouth, tongue, and soft palate as most common sites; 90% will show dysplasia; epithelial atrophy with lack of keratin production

erythroplakia

20

6th most common cancer worldwide; more than 95% of all oral malignancies

oral squamous cell carcinoma

21

leukoplakic, erythroplakic, ulcerated, exophytic, endophytic

OSCC

22

a low grade malignant epithelial tumor; characterized by a thick, wart-like surface texture; most common in smokeless tobacco users

verrucous carcinoma

23

papillary surface architecture; parakeratin clefting; broad, pushing rete ridges; minimal atypia

verrucous carcinoma

24

a pathologic cavity lined by epithelium

cyst

25

cyst with no epithelial lining

pseudocyst

26

a cyst located above the thyroid gland and beneath the base of the tongue derived from remnants of the embryonic thyroglossal tract; most common developmental cyst in the neck; in midline of neck

thyroglossal duct cyst

27

on the lateral aspect of neck; developmental cyst; derived from epithelium entrapped within lymphoid tissue of the neck during embryologic development of the 2nd branchial cleft

cervical lymphoepithelial cyst (branchial cyst)

28

a tumor with paraganglia cell differentiation; cluster of neuroendocrine cells associated with SNS and PNS; most common location is adrenal medulla; greater in people living at high altitudes

paraganglioma (carotid body tumor)

29

nests (zellballen) of round to oval chief cells surrounded by delicate vascular septae

paraganglioma

30

a subjective sensation of a dry mouth

xerostomia

31

inflammation of the salivary glands

sialadenitis

32

most common viral sialadentitis

mumps

33

most common bacterial cause of sialadentitis

S. aureus

34

mucus spillage into the soft tissues due to rupture of a minor salivary gland duct; caused by local trauma; fluid filled lesion that is often blue or translucent; lower lip is the most common location

mucous extravasation phenomenon (mucocele)

35

a mucocele in the floor of the mouth

ranula

36

calcified structure, develop within the salivary ductal system; most common location is submandibular gland

sialothiasis (salivary stones)

37

most common site of salivary gland tumors

parotid gland

38

most common sites for minor salivary gland tumors in order

palate
upper lip
buccal mucosa

39

benign salivary gland tumors
