A Case of Accessory Parotid Gland Tumor

抄録

An accessory parotid gland refers to the presence of salivary gland tissue in front of the main parotid gland. It is reported to occur at a rate of approximately 21%–70% in the general population, and a tumor arising from an accessory parotid gland is rare, accounting for 1%–7% of all parotid gland tumors. Herein, we report a case of accessory parotid gland tumor encountered by us.

The patient was a 45-year-old woman who visited our hospital with the chief complaint of a right accessory parotid gland tumor. Based on the findings of MRI and cytodiagnosis, a diagnosis of accessory parotid gland tumor was made. The patient was treated by resection of the right accessory parotid gland tumor, and histopathological examination of the resected specimen revealed the diagnosis of pleomorphic adenoma. In the 2 years since the surgery, there has been no obvious evidence of recurrence.
