A case of accessory parotid gland tumor

We herein describe a case of accessory parotid gland tumor, including diagnosis and surgical approach. The accessory parotid gland is salivary tissue separated from the main parotid gland and lying on masseter muscle. It has secondary duct empting into the Stensen's duct. The accessory parotid gland exists in 21-61 % of individuals. However, the appearance of an accessory parotid tumor is rare, with a reported frequency of 1-7.7 % of all parotid gland tumors. Surgical resection is the treatment of choice for the accessory parotid gland tumor. It is important to identify the buccal branch of the facial nerve to avoid injury to the facial nerve. The tumor in our case was surgically resected without facial nerve injury. The histopathological diagnosis was pleomorphic adenoma.
