Chondrosarcoma of the bronchus.

A primary chondrosarcoma of the right main bronchus was removed by pneumonectomy in a 74-year-old woman. The presenting symptoms were dyspnea and cough with a lung mass evident for 18 months. She is well and free of tumor 16 months later. Only eight established cases of primary chondrosarcoma arising from the lung, and four originating from the tracheobronchial tree have been previously described. The long preoperative history and the outcome so far confirm the relatively less aggressive character of the tracheobronchial as compared to the lung subdivision of primary pulmonary chondrosarcoma.
