[Bronchial lipoma treated by surgical resection; report of a case]

We report a case of bronchial lipoma, which relapsed after endoscopic treatment, and was treated by surgical resection. An abnormal shadow on chest X-ray was noted at the annual medical checkup of a 44-year-old man. Chest computed tomography (CT) demonstrated a tumor in the right basal bronchus and linear opacity on the peripheral side of that tumor. Bronchoscopic examination demonstrated a smooth polipoid tumor occluding the right basal lobe bronchus. Bronchoscopic biopsy specimens were not sufficient for histological diagnosis. We performed endobronchial resection of the tumor using electrosurgical snare, but 2 months after endoscopic treatment, the tumor relapsed. We therefore performed right S(9+10) segmentectomy. The tumor was 11 x 9mm in size and the histological diagnosis was an endobronchial lipoma. More than 4 years after resection, the patient is alive without recurrence.
