Abstract

Epithelial-myoepithelial carcinoma is a rare neoplasm comprising approximately 1% of all salivary gland neoplasms. Histopathologically, the carcinomas are characterized by a dual cell population of an inner duct-forming epithelium and an outer myoepithelial cell. They are characterized by their variable clinical course and a lack of features that predict clinical outcome. The following report describes our experience with this type of tumor. We suggest that radiation therapy and long term follow-up will be necessary because this tumor have a high risk of locoregional aggressiveness.

Key Words: Epithelial-myoepithelial carcinoma, Salivary gland
