Abstract:We describe four cases of small endobronchial neurilemmomas arising at the bronchial bifurcations. The endoscopic features of these neurilemmomas were similar to those of early carcinomas, but the neurilemmomas appeared to have less vascular proliferation. The cells of four neurilemmomas stained positive for S-100 protein on immunohistochemical examination. Only 20 cases of endobronchial neurilemmoma have been described in the literature, and most of these lesions were large and obstructed the bronchi. The possibility of neurilemmoma should be considered in the differential diagnosis of small sessile polypoid lesions found in the bronchi on bron-choscopic examination.
