A surgical case of ciliated muconodular papillary tumor

: Ciliated muconodular papillary tumor (CMPT) is a rare type of pulmonary tumor with mucoid features. Only a few cases confirmed by surgery have been reported worldwide. We report a case of CMPT following sublobectomy, with no recurrence detected in 10 months of follow-up. The accumulation of similar cases is essential for pathologists and surgeons to improve their understanding of such tumors.
