Epithelial myoepithelial carcinoma of salivary glands: a case report

Epithelial-myoepithelial carcinoma (E.M.C.) is a rare low-grade salivary gl and neoplasm that occurs in both major and minor salivary glands. It is cha racterized by tubular and solid growth pattern with a dual cell population including an inner layer of epithelial cells which are peripherically bound ed by a layer of clear myoepithelial cells. This differentiation is confirm ed by electron microscopic and immunohistochemical studies. The differentia l diagnosis included clear cell tumor of the salivary gland and metastatic renal carcinoma. The majority of these tumours arise in the parotid in wome n 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.
