Flashcards in 29. Salivary gland tumors Deck (23):
1

benign or malignant

most commolny benign
tumor in smaller glands are more likely malignant

2

location

most commonly in parotid gland

3

relationship of gland size and malignancy

tumor in smaller glands are more likely malignant

4

clinical presentation

-typically painless mass/ swelling
-facial pain or paralysis suggest malignant involvement of CN VII

5

MC malignant tumor of salivary glands
MC salivary gland tumor

MC malignant : Mucoepidermoid
MC tumor : Pleomorphic adenoma

6

Sali cystadenoma vary gland tumors - types ( and MC)

1. Pleomorphic adenoma ( benign mixed tumor) -MC
2. Mucoepidermoid
3. Warthin tumor ( papillary cystay denoma lumphomatosum)

7

Pleomorphic adenoma ( benign mixed tumor) is composed by

chondromyxoid stroma and epithelim

8

Pleomorphic adenoma ( benign mixed tumor) - management

excision with large borders

9

Pleomorphic adenoma ( benign mixed tumor) - excision complication

if incomplete excision ( tumor islands) --> ecur
-ruptured intraoperatively

10

mucoepidermoid tumor of salivary glands - histology

mucinous and squamous components

11

Warthin tumor is AKa... apperance

- papillary cystadenoma lymphomatosum
-benign cystic tumor with germinal centers
ALWAYS IN PAROTID

12

apthous ucler ( definition, presentation, treatment, apperance)

painful, superficial ulceration of the oral mucosa --> related to stress and resolves spontaneously, but often recur --> graysish base surrounded by erythema

13

Behcet syndrome - presentation

recurrent apthous ulcers, genital ulcers and uveitis

14

Behcet syndrome - causes and mechanism

causes : after viral infenction, but unknown etiology
mechanism : immune complex vasculitis of small vessels

15

oral SCC- risk factors, MC location, precurson lesion

risk factors : Tobacco , alcohol
MC location: floor of month
precursor lesion: Oral leukoplakia and erythroplakia

16

• A patient had removal of a salivary gland tumor. Which gland was likely involved?

Parotid gland

17

• A patient has a painless, moveable salivary gland mass removed. The tumor is benign, but later recurs. Why did it recur?

Recurs with incomplete excision or intraoperative rupture (it is likely a pleomorphic adenoma, a benign mixed tumor)
mm
Chondromyxoid stroma and epithelium

18

• A patient has a benign tumor made of heterotopic salivary gland tissue trapped in a lymph node, surrounded by lymphatic tissue. Diagnosis?

Warthin tumor (papillary cystadenoma lymphomatosum), which is a benign cystic tumor with germinal centers

19

• Warthin tumor is a ____ (malignant/benign) cystic tumor with ____ (germinal/follicular) centers.

Benign; germinal

20

• A patient presents with a painless, slow-growing mass and is found to have the most common type of malignant salivary tumor. What is it?

Mucoepidermoid carcinoma

21

• A patient has a painless mass in the parotid area. Histology of the lesion shows mucinous and squamous components. What do you suspect?

Mucoepidermoid carcinoma, which typically presents as a painless, slow-growing mass

22

• A patient had a salivary gland tumor rupture intraoperatively, & the tumor recurs a few weeks later.

Type of salivary gland tumor?
Pleomorphic adenoma

23

• What is another name of the papillary cystadenoma lymphomatosum?

Warthin tumor
