Pulmonary mucoepidermoid carcinoma is characterized by low-grade malignancy, development from the salivary glands of the proximal tracheobronchial tree, and the t (11;19) chromosomal translocation generating a CREB-regulated transcription coactivator 1-mastermind-like 2 (CRTC1-MAML2) fusion oncogene [6, 7]. Here, MAML2 is linked to pulmonary mucoepidermoid carcinoma.
