Benign clear cell tumor of the lung

Abstract

Clear cell tumor of the lung is a rare benign tumor. Herein, we present a case of a 51-year-old man who had an abnormal pulmonary nodule occasionally found on chest roentgenogram. A computed tomographic scan showed a solitary nodule (approximately 15 mm in diameter) in the lingular segment of the left upper lobe. The patient underwent a lobectomy for the tumor. The pathologic report supported the diagnosis of clear cell tumor of the lung. The patient showed no evidence of recurrence or metastasis 2 years postoperatively.
