Fine needle aspiration cytology of mucoepidermoid carcinoma. A diagnostic problem.

Abstract

The cytomorphologic findings in fine needle aspirates from 18 cases of histologically confirmed primary mucoepidermoid carcinoma of the salivary gland were reviewed and correlated with the findings on the tissue sections. An accurate diagnosis of these tumors in fine needle aspirates was possible when all three components (i.e., epidermoid cells, intermediate cells and mucus-producing cells) were identified. The pitfalls in the cytologic diagnosis of this tumor are discussed.
