Ciliated muconodular papillary tumor (CMPT) was a rare tumor with low-grade malignancy. The histopathogenesis of CMPT remains unclear. Three typical components are ciliated columnar cells, goblet cells, and basal cells. Limited resection is sufficient for CMPT. No recurrences or metastases have been reported. Herein, we reported a 73-year-old man who presented with right lower lobe partial sold nodule. He received partial resection for the right lower lobe tumor. CMPT was confirmed. However, contralateral left lower lobe ground-glass opacity (GGO) was found 3 months later. He received partial resection for the left lower lobe GGO. CMPT was diagnosed again. Double primary CMPTs were recognized because morphologic patterns were different. At his 2-year follow-up, there was no local recurrence or metastasis.
