Flashcards in 1 - ENT - Head and neck - Salivary gland disease - Benign and Intermediate salivary gland tumours Deck (12):
1

80% of salivary tumours are where? % of these are benign? % of SML tumours benign? % of minor salivary galnd tumours benign? unless what?

-80% parotid
-80% benign
-60% SML tumours benign
-30%MGT's benign - unless outside mouth/oropharynx - always malignant)

2

Benign salivary gland tumours - incidence and aetiology

1 per 10000
unclear, may be related to previous radiation

3

Benign salivary tumours - sex and pathology

slightly more common in F
arise from reserve stem cells

4

2 types of benign salivary tumours

pleomorphic adenoma 80%
adenolymphoma - WARTHIN's tumour

5

Pleomorphic adenoma - usually where? in who? growth rate?

usually in superficial lobe of parotid
typically middle aged, slow growing

6

Pleomorphic adenoma - Ix + what may develop and when?

FNA, USS/CT
Adenocarcinoma may develop within 10-15y after

7

MGMT of pleomorphic adenoma

superficial parotidectomy
surgical excision
radiotherapy
safe to watch and wait if elderly

8

Adenolymphoma / Warthin's tumour - originates from? sex? what are they and where? mgmt?

-from parotid lymph nodes - not actually lymphoma
-8:1 M;F
-soft cystic masses in tail of parotid, may be bilateral
-mgmt partial parotidectomy

9

two types of intermediate salivary gland tumours

mucoepidermoid tumour
acinic cell

10

mucoepidermoid tumours - originates from? % occur in parotid? most common demographic? type of tumour? recurrence rate?

o-from interlobular and intralobular ducts
-90% in parotid
-more common in middle aged women, most common SGT in kids
-cystic
-30%

11

mucoepidermoid tumours - low grade vs high grade?

low - slow growing, painless Rx - local resection and follow up
high - grow rapidly, painful, local invasion and meta spread Rx - radial resection + radiotherapy

12

Acinic cell - from what? % in parotid? characteristics of tumour? mgmt?

from reserve epithelial cells
99% parotid
slow growing, solid tumours
Mets rare
mgmt - local resection
