Mammary analogue secretory carcinoma (MASC) has recently been recognized as a salivary gland tumour that is characterized by the ETV6-NTRK3 fusion gene.
Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that morphologically resembles mammary secretory carcinoma and carries the identical ETV6-NTRK3 fusion gene.
This is the first case with high grade histology that arise from minor salivary gland and it emphasizes the importance of molecular screening of salivary gland tumor with high-grade histology for ETV6-NTRK3 translocation.
