Abstract
|
|
|
Epithelial-myoepithelial carcinoma is a very rare malignant tumor accounting for less than one percent of
salivary 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 location.
