肺軟骨腫の1例

Pulmonary Chondroma；Report of a Case

はじめに　肺良性腫瘍は肺腫瘍全体の2～5％を占める1）．そのほとんどは肺過誤腫であり，肺軟骨腫の頻度はまれである2）．われわれは肺軟骨腫の症例を経験したので文献的考察を加えて報告する．

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.
