Bronchoscopic surgery for a solitary tracheal tumor of tracheobronchopathia osteochondroplastica.

Tracheobronchopathia osteochondroplastica is a rare benign condition in which multiple cartilaginous or bony submucosal nodules project into the trachea or bronchi. A 71-year-old man complained of cough for 3 months. Computed tomography scanning revealed a calcified tracheal tumor near the tracheal bifurcation. Pulmonary function testing indicated airflow limitation, and bronchoscopic examination confirmed a solitary rigid tumor. Bronchoscopic resection was performed under general anesthesia, and the tumor was detached by cauterizing its stem with high-frequency coagulation. The tumor was pathologically indicative of tracheobronchopathia osteochondroplastica. After surgery, the clinical signs of cough and dyspnea resolved and pulmonary function normalized.
