5

6

What is a mucocele?

Obstruction of oral mucosa mucous gland resulting in a cystic dilation of duct filled with mucin. Due to trauma or inflammation. Not neoplastic.

7

T/F- Leukoplakia and erythroplasia are potentially premalignant lesions?

True

8

Can leukoplakia be removed by simple scraping of the lesion?

no

9

What causes leukoplakia?

irritation and inflammation

10

T/F- leukoplakia is usually malignant?

False, only 1-15% are pre-cancerous

11

Looking at leukoplakia under a microscope, what two characteristics will you see?

1.kyperkeratosis
2. mucosal epithelial hyperplasia

12

Is erythroplasia more or less likely to progress into cancer than leukoplakia?

erythroplasia (50%)
leukoplakia (1-15%)

13

T/F- in general prognosis worsens corresponding to the further back in the mouth/phayrnx the lesion is?

true

14

What is the most common malignant tumor of the oral region?

squamous cell carcinoma

15

What virus is often responsible for causing rhinitis?

adenovirus

16

Repeated episodes of allergic rhinitis can lead to what condition of the nose?

thick mucosa and nasal polyps

17

Name 2 causes of necrotizing granulomatous sinusitis

1. wegeners granulomatosis

18

T/F- we would expect to see fibrinoid necrosis of vessels in wegeners granulomatosis

true

19

T/F- mucor (zygomycetes infection is rarely fatal

False, fatal infections often occur due to extension of fungal elements into the brain. This is a medical emergency.
