A 66-year-old man was pointed out a nodular shadow in the right lower lobe by chest computed tomography (CT) 4 years ago. Since the size of the shadow has been increasing for 4 years, he hospitalized for surgery. Partial resection of the right lower lobe was performed. Histopathologically, the tumor was composed of cartilage tissue without epithelial components, and was diagnosed as a chondroma. Postoperative course was uneventful and there has been no recurrence at 1 years and 8 months after surgery.
