Primary Mucoepidermoid Carcinoma of the Lung with Prominent Clear Cells

摘要

Mucoepidermoid carcinoma of the lung is a rare malignancy of salivary gland-type origin. We report a case of a 21-year-old man with a right mainstem bronchus mass composed predominantly of clear cells. This case represents a rare primary pulmonary low-grade mucoepidermoid carcinoma positive for MAML2 rearrangement by fluorescence in situ hybridization with a prominent clear cell component.
