Answer 7

if benign: 1. pleomorphic adenoma 2. Warthin tumor if malignant: 1. mucoepidermoid carcinoma

Question 8

if there is a tumor in the submandibular gland, what could it most likely be? (differential diagnosis including benign and malignant)

Answer 8

if benign: 1- pleomorphic adenoma if malignant: 1. adenoid cystic carcinoma

Question 9

1 Developmental disorder associated with salivary glands

Answer 9

lingual mandibular salivary gland depression (stafne bone cavity)

Question 10

2 potentially neurological disorders associated with salivary flow

Answer 10

1- Sialorrhea 2- Xerostomia

Question 11

How do we not confuse a canalicular adenoma with a fibroma?

Answer 11

a canalicular adenoma can be moved around all over the place (because it is below the lamina propria)

Question 12

3 characteristics of a pleomorphic adenoma

Answer 12

1- firm to palpation

2- asymptomatic

3- mobile

Question 13

What can happen if we do not treat a pleomorphic adenoma?

Answer 13

Can become malignant

Question 14

When there is a tumor that is causing partial paralysis or tingling perhaps in a patients face… what are we thinking?

Answer 14

Were thinking the neoplasm is malignant because it is invading/encroaching on the nerve
