Abstract

A 55-year-old Japanese man presented with rapidly growing tumor in the left parotid region without any symptoms. Based on the fine-needle aspiration cytology report of parotid epithelial malignant tumor (suggestive of salivary duct carcinoma), the left parotidectomy was performed. Histopathology and immunohistochemistry examinations revealed features of salivary duct carcinoma. Although salivary duct carcinoma comprising a small proportion of salivary gland tumors and is known to be aggressive, he is free from recurrence and metastases 36 months after the surgery and radiation therapy.
