oral swellings

Question 1

what are the various disease processes that can cause tumours/enlargements in the mouth

Answer 1

Foci of granulation tissue and infection
Benign and malignant neoplasms
Salivary glands
Cyst
Abscess
Mucous extravasation and retention in minor 

GNSCAM

Question 2

common oral swellings/enlargements on the lips and buccal mucosa

Answer 2

1. fibroepithelial polup
2. denture hyperplasia
3. mucocele
4. connective tissue tumours
5. salivary tumour
6. squamous cell carcinoma

Question 3

what is denture hyperplasia

Answer 3

reactive lesion due to excessive and chronic mechanical pressure on vestibular oral mucosa (ill fitting denture). may be inflammatory in nature due to poor denture hygiene, ill fitting denture

Question 4

What is the most common site for a mucocele

Answer 4

lower lip

Question 5

what causes a mucocele

Answer 5

usually local trauma, causing rupture of salivary duct and mucin spills into surrounding soft tissues

Question 6

most of salivary gland tumours occur in the

Answer 6

parotid gland (pleomorphic adenoma, warthin tumour)

Question 7

second most common site for salivary gland tumours is

Answer 7

minor salivary glands (relatively high proportion are malignant, 40% pleomorphic adenoma)

Question 8

where in the oral cavity do minor salivary gland tumours most commonly occur

Answer 8

palate (post hard palate, soft palate have greatest concentration of glands)

Question 9

etiological factors for scc

Answer 9

tobacco smoking, alcohol, iron deficiency, radiation, immunosuppression, candidal infection

Question 10

common oral swellings/enlargements on the gingiva

Answer 10

1. periodontal abscess
2. fibrous epulis
3. pyogenic granuloma
4. giant cell epulis
5. peripheral ossifying fibroma
6. gingival cyst
7. peripheral odontogenic cyst
8. SCC

Question 11

what is pyogenic granuloma

Answer 11

exuberant tissue response to local irritation eg gingival irritation and inflammation from poor OH

characteristically ulcerated

children, young adults, pregnant women

Question 12

where does peripheral ossifying fibroma occur

Answer 12

exclusively on the gingiva

Question 13

gingival cyst has a predilection for which teeth

Answer 13

mandibular canine and premolar

Question 14

enlargements at the palate could be

Answer 14

abscess (lateral incisors, palatal root of molar)
torus
salivary gland tumour (post palate)

Question 15

where can pyogenic granuloma occur

Answer 15

gingiva, tongue

Question 16

enlargements on the oral floor and ventral tongue

Answer 16

mucocele/ranula
lymphoid aggregates
lymphoepithelial cyst
scc

Question 17

what is a lymphoepithelial cyst

Answer 17

oral lyphoid tissue epithelium invaginates into tonsillar tissue to form tonsillar crypt filled with keratin.

<1cm diameted

yellow/white

overlying mucosa smooth, non ulcerated

Question 18

enlargements in the bone

Answer 18

torus, fibrous dysplasia, exostosis, odontogenic cyst/tumour, osteoma, osteosarcoma

Question 19

fibrous dysplasia vs osseous dysplasia

Answer 19

osseous dysplasia usually does not cause expansion; normal bone replaced by abnormal bone

fibrous dysplasia bone replaced by excessive proliferation of cellular fibrous connective tissue, expansile mass

Question 20

osteoma usually at

Answer 20

body of mandible (posterior to premolars on lingual surface)

Question 21

blue-purple enlargements

Answer 21

kaposi sarcoma
hemangioma
hematoma
mucocele
giant cell epulis

Question 22

prognosis of mucosal melanoma vs cutaneous melanoma

Answer 22

mucosal melanoma usually present at more advanced stage, more aggressive

Question 23

yellowish enlargements

Answer 23

lipoma

granular cell tumour

Question 24

enlargements that are firm and movable

Answer 24

granuloma
connective tissue neoplasm
adenoma

Question 25

enlargements that are firm and fixed

Answer 25

granular cell tumour

fibromatosis

Question 26

indurated and fixed lesions in the oral cavity

Answer 26

SCC
BCC
salivary adenocarcinoma
sarcoma
lymphoma 
melanoma

Question 27

bony hard lesions in the oral cavity

Answer 27

osteoma
fibro osseous lesions
odontogenic cyst
