Mammary analog secretory carcinoma (MASC) of the parotid gland is a rare and recently described lesion. We report the case of a 46-year-old man with a tumor of the parotid gland which was carried to the diagnosis of MASC. Diagnostic was confirmed by highlighting the ETV6-NTRK3 gene translocation. However, some morphologic and immunohistochemical features are suggestive of this entity. This carcinoma should be distinguished from its main differential diagnoses: acinic cell carcinoma and low grade cribriform cystadenocarcinoma.
