MAML2 and mucoepidermoid carcinoma: Recent advances such as the identification of MECT1-MAML2 fusion in mucoepidermoid carcinoma (MEC), the recognition of a new disease entity (mammary analogue secretory carcinoma [MASC]) characterized by the ETV6-NTRK3 fusion gene and the discovery of the MYB-NFIB oncogene in adenoid cystic carcinoma (ACC), have begun to refine our knowledge of salivary gland carcinogenesis [3].
