We report three cases of bronchial mucoepidermoid carcinoma (BMEC) of low-g
rade malignancy with a relafase-free follow up.
BMEC are rare tumors. The microscopic findings distinguish low-grade tumors
which occur in children and young adults and high-grade tumors concerning
older patients; this grading is based on the study of the epidermoid compon
ent. If possible, conservative therapy is appropriate in low-grade tumors.
The prognosis of high-grade tumors is poor.
