Abstract
|
|
|
|
Mammary analogue secretory carcinoma (MASC) has histologic similarities to not only acinic cell carcinoma but also other low grade cystadenocarcinoma, and has similar features to breast secretory carcinoma. MASC was not described through the existing classification system previously. But, MASC was distinguished from other salivary gland tumors by Skalova et al. in 2010, MASC has ets variant gene 6-neurotrophic tyrosine kinase, receptor, type 3 (ETV6-NTRK3) translocation. So far, there are 4 cases of MASC recognized in the head and neck region in Korea. One of the four is a tumor from the submandibular gland, and the other three are of the parotid gland. In this case report, we report a 40-year-old man with a MASC of the parotid gland, who presented with right infra-auricular mass.
