Fine-needle aspiration biopsy of recurrent oncocytic carcinoma of parotid gland.

A 65-year-old man presented with a right cheek mass. His past history was significant for resection of primary oncoctyic carcinoma of the right parotid gland 5 years ago. Fine-needle aspiration biopsy of the right cheek mass was performed and demonstrated oncocytic cells without significant cytologic atypia. On the basis of the past history and comparison of the histology of previously resected specimen, the cytologic impression was consistent with recurrent oncocytic carcinoma of the salivary gland. The cytologic differential diagnosis should include other primary salivary gland neoplasms and metastatic disease.
