Abstract
We present a 65-year-old man with an enlarged mass in the right parotid gland. A fine-needle aspiration cytology suspected Warthin's tumor. The ill-defined margin of the tumor in diagnostic imaging and unexpected clinical course of the occurrence of facial nerve paralysis suggested malignant neoplasm. The patient was treated with surgical resection of the primary site and neck following radiation therapy. Pathologic diagnosis was a salivary duct carcinoma. Difficulty in early diagnosis of this tumor may result in local extension, early metastasis to regional lymph nodes and distant sites, and death.
