       Salivary duct carcinoma is an uncommon, relatively unknown, and clinically aggressive carcinoma of salivary origin. Recently, we treated a rare case of salivary duct carcinoma arising from the accessory parotid gland. The patient was a 68-year-old male who complained of left cheek swelling. The mass was located in left mid-cheek. Fine needle aspiration biopsy and open biopsy of the mid-cheek mass revealed malignant cells, but the pathological diagnosis was not settled. The mass in the mid-cheek was resected en-block including the buccal branches of the facial nerve, the superficial parotid gland, a part of the masseter muscle, and the skin right above the tumor. A pathological examination identified comedo necrosis and a final diagnosis of salivary duct carcinoma was made. The patient was treated with postoperative radiation therapy and has been free of tumors for 10 months.

Key words : salivary duct carcinoma, accessory parotid gland, pathological diagnosis, comedo necrosis
