Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that shares the same histologic appearance and ETV6 gene (12p13) rearrangement as secretory carcinoma of the breast.
Mammary analogue secretory carcinoma (MASC) is a recently recognized salivary gland tumor harboring an ETV6-NTRK3 translocation similar to secretory carcinoma of the breast.
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.
Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that has morphologic features similar to secretory carcinoma of the breast and that also harbors the same ETV6 translocation.
