A case of carcinoma ex pleomorphic adenoma in the accessory parotid gland

Abstract

We report a case of carcinoma ex pleomorphic adenoma in the accessory parotid gland. The patient was a 48-year-old man who presented with a hard mass in his left cheek. We suspected an accessory parotid gland tumor based on an imaging examination. Fine needle aspiration biopsy revealed possibly pleomorphic adenoma. We performed surgical resection with an incision above the tumor, and the pathology results showed carcinoma ex pleomorphic adenoma. After the diagnosis, we performed postoperative chemoradiotherapy using cisplatin. There was no recurrence or metastasis during 27 months of follow-up. In this case, we chose to make a skin incision above the tumor, but after a postoperative review, we found that surgeons should consider an approach where neck dissection and parotidectomy can be connected by the same incision line.
