title: Synchronous benign and malignant tumors in the ipsilateral parotid gland.
abstract: Synchronous benign and malignant tumors in the ipsilateral salivary glands are extremely rare. We report a unique case of synchronous unilateral parotid tumors in a 71-year-old man. The main parotid lesion was preoperatively suggested to be adenocarcinoma by fine needle aspiration cytology. A coexisting Warthin's tumor was also diagnosed on microscopic examination of total parotidectomy specimens. We describe this case of rare synchronous salivary gland tumors exhibiting both benign and malignant components with a review of the literature.
