Abstract:
Epithelial-myoepithelial carcinoma of intercalated duct(origin) is a recently described tumor characterized by its typical biphasic pattern of central duct like cell and peripheral clear cell. We described a case of epithelial-myoepithelial carcinoma in a 10-year-old boy. Microscopically, the tumor showed typical biphasic pattern, diffuse proliferation of clear cells and linining epithelial cells of tubular structures. Immunohistochemically, the clear cell showed positive reaction to S-100 protein, and the epithelial cells expressed cytokeratin indicating myoepithelial and epithelial differentiation respectively. Biphasic differentiation of the tumor cells could be also proved by electronmicroscopic study.
