[Solitary squamous papilloma of the bronchus: report of a case].

A 30-year-old man had a history of smoking 1-2 packs per week for 10 years. He had suffered from a productive cough with whitish mucoid sputum for two months. Left anterior chest pain, palpitation and shortness of breath developed about two weeks before his admission. Chest radiographs showed collapse of the left lower lobe. Bronchoscopy revealed a strawberry-like tumor on the left main bronchus with nearly complete obstruction. Pathology showed bronchial squamous papilloma with surface dysplasia, but no evidence of malignancy. The obstructed lumen was completely reopened by bronchoscopic Nd-YAG laser therapy. Unfortunately, the tumor recurred two months later. Therefore a sleeve resection of the tumor was performed six months after the laser photoresection. After two years of follow-up, no evidence of tumor recurrence has been found.
