Abstract

Mammary analogue secretory carcinoma (MASC) of the salivary gland is a newly classified pathologic entity since 2010. Prior to its recognition, MASC was diagnosed as low-grade cystadenocarcinoma, acinic cell carcinoma, and mucoepidermoid carcinoma. MASC shares common histological and genetic characteristics with secretory carcinoma of the breast and has a distinct feature of the ETV6-NTRK3 fusion gene. Treatment of MASC in salivary gland is mainly wide surgical resection of the tumor. Prognosis of MASC is similar to other low-grade salivary gland carcinomas. Herein, we report a case of MASC developed in a parotid gland with a review of the literature.

Key Words: Mammary analogue secretory carcinoma, Parotid gland, Salivary gland
