Cytomorphologic features of salivary duct carcinoma on fine needle aspiration biopsy. A case report.

Salivary duct carcinoma is an uncommon salivary gland malignancy resembling intraductal carcinoma of the breast. We report a case of salivary duct carcinoma in which fine needle aspiration biopsy was performed preoperatively. The cytologic features included tumor cells with abundant, finely granular cytoplasm and focal mucin positivity as well as sheets and tissue fragments demonstrating a distinctive cribriform pattern.
