Abstract
Epithelial-myoepithelial carcinoma(EMC) is a rare, low grade malignant tumor of the salivary glands. The EMC has a distinctive histological appearance comprising ductal structures with an inner epithelial cell component and an outer layer of myoepithelial cells which show plump clear cytoplasm. The cytologic features of the EMC have been rarely described. A correct cytological diagnosis to this rare tumor is difficult with high false negative rate. We report a case of EMC in which fine needle aspiration cytologic findings were misinterpreted as a pleomorphic adenoma.
