Abstract:
Epithelial-myoepithelial carcinoma is a very rare malignant tumor accounting for less than one percent of sa1ivary gland neoplasms. Histologically, the tumor consists of a mixture of trabecular structure with double-layered arrangement of inner ductal cells and outer myoepithelial cells. Immunohistochemistry and electron microscopy confirm dual differentiation toward myoepithelial and ductal cells. We report a 22-year-old man with epithelial-myoepithelial carcinoma arising from nasal cavity, one of the most unusual locations.
