Abstract
A 44-year-old heavy male smoker complained cough and sputum. Chest X-ray film showed no abnormal shadow, but bronchoscopic findings revealed a polypoid tumor with a smooth surface at the orifice of the right basal bronchus. The histological diagnosis was solitary bronchial papilloma. Right basal segmentectomy was carried out. The resected tumor specimen had arisen from the bifurcation between B^7 and B^8, no malignant cells were detected in spite of further examinations. Solitary bronchial papilloma is relatively rare, and to our knowledge, only 37 cases including our cases, have been reported in the Japanese literature. In 2 cases, bronchial papillomas developed malignant change, and in 5 cases, those tumors were accompanied by lung cancer. It was considered that solitary bronchial papilloma should be surgically resected whenever possible.
