We report two cases of palate myoepithelioma that were diagnosed histologically and immunohistochemically. In addition, the diagnostic reliability and usefulness of aspiration cytology, which had been done preoperatively, is discussed. Both cases were clinically suspected to be pleomorphic adenoma, but aspiration cytology led to a probable diagnosis of myoepithelioma. Aspiration cytology can be helpful and useful for the differential diagnosis of preoperative lesions, as well as for the preparation of research methods and materials.
