By Dr. Vishaal Bhat on Tuesday 1 January 2008 with 0 comments



  • Most common salivary gland tumour overall

  • Accounts for 60 – 70% of parotid tumours, 40 – 60% of submandibular tumours, and 40 – 70% of minor salivary gland tumours

  • Peak incidence between 30 and 50 years; female to male ratio 3:1

  • Slowly-growing painless, firm masses—in the parotid, most occur in the superficial lobe

  • A variety of growth patterns may be seen histologically—the basic components are epithelium, myoepithelium and stroma .

  • Recurrence may occur if the tumour is inadequately excised.
