    Objectives: We evaluated the clinical, radiologic, and bronchoscopic findings in benign endobronchial tumors and treatment outcomes of bronchoscopic intervention. Methods: We retrospectively reviewed records of patients with benign endobronchial tumor who underwent rigid bronchoscopic intervention, and evaluated outcomes of 55 patients with hamartomas, leiomyoma, papilloma, carcinoid, and schwannoma, between April 1999 and July 2012. Results: The most common types of tumor was hamartomas (n=24) followed by leiomyoma (n=16), papilloma (n=7), carcinoid (n=5), and schwannoma (n=3). Clinically, 46 patients had respiratory symptoms. On chest CT, all patients showed mass or nodular lesions in tracheobronchial tree and were frequently accompanied by atelectasis (n=26) or obstructive pneumonia (n=17). At bronchoscopy, most tumors showed round shape, smooth surface, and pedunculated base. As a result, 49 of 55 patients had complete resection, and 1 patient with hamartoma had partial resection. However, 5 patients subsequently received surgery (2 carcinoids, 2 leiomyomas, and 1 hamartoma). Recurrences occurred in 4 papillomas and in 1 carcinoid, and 4 recurrent papillomas needed repeated bronchoscopic interventions and 1 recurrent carcinoid received surgery. The proportion of pedunculated base and no bleeding were high in successful removal group compared with unsuccessful removal group who had surgery, complications, or recurrence. Conclusions: We described characteristics of benign endobronchial tumors and provided the clinical data on the value of bronchoscopic intervention.
