Pleomorphic adenoma arising in accessory parotid gland: Report of a case

Abstract

An accessory parotid gland is located anterior to the main parotid gland and occurs in about 30 per cent of human cadavers. Tumors arising in accessory parotid tissue are rare. This case report describes a pleomorhic adenoma arising in the accessory parotid gland.
A 21-year-old male was seen in 1984 with a soft tissue mass in the left cheek. A sialogram revealed a duct system of accessory parotid tissue and unusual stenosis of Stensen's duct. At operation, the mass was freed from the main parotid tissue and enucleated easily. Histologically, the mass was pleomorphic adenoma.
