Pleomorphic adenoma arising in accessory salivary tissue with constriction of Stensen's duct.

Abstract

AbstractAccessory salivary gland tissue is well recognized and is found in 21 per cent of the population. Tumours of the accessory salivary tissue are rare and comprise only 1 per cent of all parotid gland tumours.A pleomorphic adenoma of Stensen's duct is described. A circular constriction of this duct by the tumour with retention of saliva in the parotid gland was observed.
