A 59-year-old woman was admitted to the hospital because of intermittent fever and right side chest pain. She has a same episode eight months before this entry. Chest CT scan demonstrated ill-defined parenchymal consolidation containing dilated bronchi of right lower lung field, but no endobronchial mass in the bronchial trees. Fiberoptic bronchoscopy seeking the cause of recurrent pneumonia revealed a small, round mass nearly completely obstructing the lumen of basal segmental bronchus of right lower lobe. The diagnosis of bronchiolar papilloma was made from the biopsy specimens of the bronchoscopic examination. The patient was treated with right lower lobectomy because of irreversible secondary changes below the obstructed bronchus. This thoracotomic excision resulted in complete relief of symptoms and the postoperative course was uneventful for 12 months. Here we report a extremely rare tumor with a brief review of literatures.
