Sebaceous variant of mucoepidermoid carcinoma of the salivary gland. A case report with cytohistologic correlation.

The findings on fine needle aspiration biopsy cytology of a case of sebaceous variant of mucoepidermoid carcinoma of the parotid gland are described. The aspirates consisted predominantly of uniform intermediate-type epithelial cells, which led to erroneous diagnosis of a benign neoplasm. The cytologic features of the intermediate, clear, mucinous and sebaceous cells were correlated with the different histologic patterns seen within the neoplasm. Problems encountered with the diagnosis are discussed.
