Flashcards in head and neck Deck (38):
1

rhinitis

inflammation of nasal mucosa; adenovirus is common cause

2

rhinitis presetation

sneezing, congestion, runny nose

3

allergic rhinitis

type I HSR, inflammatory infiltrate with eosinohpils; assoc with asthma and eczema

4

nasal polyp

protrusion of edematous infalmed nasal mucosa; usually secondary to repeated bouts of rhinitis; child with polyps check for CF; ASA-intolerant asthma adults have polyps

5

angiofibroma

benign tumore of nasal mucosa composed of large BV and fibrous tissue; classica in adolescent males

6

angiofibroma presentation

profuse epistaxis

7

nasopharyngeal carcinoma

nasopharyngeal epitheliam malignant tumor; EBV assoc.; classically seen in african children and chinese adults

8

Bx of nasopharyngeal carcinoma

pleomorphic keratin + epithelial cells in background of lymphocytes

9

acute epiglottitis

H flu type B is most common causes especially in non-immunized

10

acute epiglottis presenataion

high fever, drooling, sorethroat, dysphagia, muffled voice, inspire stridor; risk of airway obstruction

11

laryngotracheobronchitis (croup)

inflamm of upper airway; parainfluenza is most common causes

12

laryngotracheobronchitis (croup) presetation

hoarse barking cough and inspire stridor

13

vocal cord nodule

from excessive use; composed of myxoid connec. tissue; usually B/L

14

vocal cord nodule presentation

hoarseness that resolves then with rest

15

laryngeal papilloma

benign tumor of vocal cord; HPV 6/11; koilocytic change; single nodule in adults; and multiple in children; presentation is hoarseness

16

laryngeal carcinoma

SCC from vocal cord epi lining; risk factos are EtOH and tobacco

17

laryngeal carcinoma presentation

hoarseness, cough, stridor

18

cleft lip and palate

full thickness defect of lip or palate; due to fail of facial prominences to fuse; both usually occur together

19

aphthous ulcer

painful, superficial ulceration of oral mucosa; arises in relation to stress and resolves spontaneously but can recur;

20

aphthous ulcer histo

grayish base surrounded by erythema

21

behcet syndrome

recurrent aphotous ulcer + genital ulcers and uveitis; due to immune complexz vasculitis involveing small vessels; can be seen after viral infection

22

oral herpes

vesicles involving oral mucosa that rupture, resulting in a shallow, painful, red ulcers; due to HSV-1

23

oral herpes infection happens when

primary infection in childhood; virus is dormant in the trigeminal nerve

24

oral herpes reactivation by

stress and sunlight; leads to the vesicles on lips

25

SCC of oral mucosa

risk factors are tobacoo and etoh; location is usually floor of mouth

26

leukoplakia and erythroplakia are precursor lesions for

SCC for mouth; and is Bx to rule out carcinoma

27

leukoplakia cannot be what

scrapped away like oral candidiasis

28

leukoplakia is due to

EBV; hairy also

29

erythroplakia

vascularized leukoplakia; indicates angiogenesis; more often is considered dysplasia

30

mumps

mumps virus; rebulst in B/L inflamed parotid

31

mumps other targets

orchitis, pancreatitis, aseptic meningitis; serum amylase increased (due to salivary gland or pancreas involvement); orchitis in teenagers carries risk of sterility orchitis in pt greatr than 10)

32

sialadenitis

salicary gland inflammation; commonly due to obstructing stone causing S. aureus infection; usually unilateral

33

pleomorphic adenoma

benign tumor of stromal and epi tissue including glands; most common tumor of salivary; usually in parotid

34

pleomorphic adenoma presentation

mobile, painless, circumscribed mass at anlge of jaw

35

pleomorphic adenoma has high rate of

recurrance; can have small islands that peirce thru tumor capsule; irregular margins

36

sign that tells you the pleomorphic adenoma has become carcinoma

signs of facial nerve damage

37

warthin tumor

benign cystic tumor with abundant lympho and germinal centers; 2nd most common of salicary glands; almost always in parotid

38

mucoepidermoid carcinoma

malignant tumor composed of mucinous and squamous cells; usually in parotid that commonly involves facial nerve
