[Intrabronchial leiomyoma treated with endoscopic resection; report of a case].

A 63-year-old female presented with an abnormal shadow on a chest X-ray. A serial chest computed tomography (CT) showed ground-glass attenuation, which measured 2 cm on S1+2 of the left lung. When bronchofiberscopy was performed to make a diagnosis, a tumor with a smooth surface was revealed which obstructed the right middle bronchus. Leiomyoma was thus diagnosed. At first, a wide wedge resection of left lung tumor was performed. Secondly, a bronchus tumor was successively removed using a high frequency snare and a laser by a bronchofiberscopy. Her postoperative course was uneventful. Leiomyoma of the bronchus is rare benign tumor. This report describes the performance of a resection using bronchofiberscopy with good results.
