Salivary gland tumours

Salivary gland tumours are variable in location, origin and malignant potential. 

Pathology

In general, the ratio of benign to malignant tumours is proportional to the gland size; i.e., the parotid gland tends to have benign neoplasm, the submandibular gland 50:50 and the sublingual glands and accessory glands mostly malignant. Due to the size discrepancy in absolute numbers parotid gland has the most tumours.

Location
  • parotid gland: 70%
  • minor salivary glands (including sublingual): 22% with the palate being most frequent (see: minor salivary gland tumours)
  • submandibular gland: 8%

Overall ~80% of all parotid masses are benign, and the majority of these are pleomorphic adenomas

Subtypes
