A Case of Tracheobronchopathia Osteoplastica Detected by Bronchoscopical Examination for Adenoid Cystic Carcinoma of the Lung

Abstract

A 38-year-old man complained of cough and sputa. His chest roentgenogram showed a left hilar tumor shadow with an atelectatic upper lobe of the left lung. Bronchoscopic examination revealed a stenotic orifice of the left upper bronchus. Biopsy revealed an adenoid cystic carcinoma involving the stenotic bronchial lesion. In addition, many small yellow-white nodules noticed by bronchoscopy in the trachea throughout bilateral main bronchi were diagnosed histologically as tracheobronchopathia osteoplastica. He has been doing well for eight years after a total pneumonectomy and no remarkable change has been seen bronchoscopically in these osteoplastic lesions.
