Key Words: Neurogenic tumor • Bronchial tumor • Schwannoma
A 41-year-old man was referred for the evaluation of a left hilar mass (Fig. 1
). Bronchoscopy showed stenosis of the orifice of lingular bronchus (Fig. 2
). Lingulectomy was performed and the tumor was completely resected. Pathology confirmed the diagnosis of schwannoma (Antoni type A) with no malignant cells.

Fig. 2. Bronchoscopy showed stenosis of the orifice of lingular bronchus compressed by an extra-luminal mass, but the bronchial mucosa was normal in appearance with no tumor exposure (A). Histologically, the tumor was composed of spindle cells with the palisading of the nuclei and diagnosed as benign schwannoma showing an Antoni type A (H&E stain, original magnification x100) (B).
