Pleomorphic adenoma of the accessory parotid gland: A case report

Abstract

We report a case of pleomorphic adenoma in the accessory parotid gland. In March 2004, a male in his late twenties visited our hospital with the chief complaint of a mass in the right cheek. MRI, ultrasonic, and sialography showed that the mass was located in the right accessory parotid gland.
Specimens obtained by needle biopsy suggested that the mass was mostly pleomorphic adenoma. We removed the mass that was located anterior to the parotid gland and surrounded by masseter muscle, zygomatic branches of facial nerves, and parotid duct, with a parotidectomy-style excision.
The mass was removed easily without postoperative complications such as facial paralysis. The final pathological diagnosis was pleomorphic adenoma.
