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. Prior to its recognition, MASC cases were commonly labeled acinic cell carcinoma and adenocarcinoma, not otherwise specified. Despite distinctive histologic features, MASC may be difficult to distinguish from other salivary gland tumors, in particular zymogen-poor acinic cell carcinoma and low-grade salivary duct carcinoma. Although characteristic morphologic and immunohistochemical features form the basis of a diagnosis of MASC, the presence of an ETV6-NTRK3 gene fusion is confirmatory. Given its recent recognition the true prognostic import of MASC is not yet clearly defined.

Initial Description

Objective. Secretory carcinoma is a recently described entity with characteristic immunoprofile and ETV6 (12p13) rearrangement. Before its initial description, it was generally diagnosed as acinic cell carcinoma (ACCi). We evaluated immunoprofile and ETV6 rearrangement in cytological and surgical cases of previously diagnosed ACCi, in an attempt to identify any misclassified SC. Methods. Fifteen cytology and surgical cases of ACCi diagnosed over a 13-year period were retrieved and subjected to immunohistochemistry for S-100, mammaglobin, GATA-3 and DOG-1 as well as FISH for ETV6 (12p13). Results. Of the 8 cytology cases, only 1 was positive for S100, GATA-3, and mammaglobin, and negative for DOG-1. It also demonstrated ETV6 rearrangement and was reclassified as SC. The same immunoprofile was present in 2 of the 13 surgical cases. ETV6 rearrangement characterized by 3′ interstitial deletion was detected in one of these cases and was reclassified as SC. Immunohistochemistry and ETV6 rearrangement were useful in identifying 2 (13.3%) cases misclassified as ACCi. Conclusions. Characteristic immunoprofile and ETV6 gene rearrangement may prove useful in identifying cases of SC. The presence of ETV6 3′ interstitial deletion in one of our cases suggests that there may be additional ETV6 related genetic alterations contributing to the pathogenesis of SC.
