[Epithelial-myoepithelial carcinoma of the salivary glands: report of a case].

Epithelial-myoepithelial carcinoma (E.M.C.) is a rare lowgrade salivary gland neoplasm that occurs in both major and minor salivary glands. It is characterized by tubular and solid growth pattern with a dual cell population including an inner layer of epithelial cells which are peripherically bounded by a layer of clear myoepithelial cells. This differentiation is confirmed by electron microscopic and immunohistochemical studies. The differential diagnosis included clear cell tumor of the salivary gland and metastatic renal carcinoma. The majority of these tumours arise in the parotid in women with a peak incidence from the 6th to the 8th decade. We report a case of parotidic E.M.C. in a 33 year old man.
