Abstract
A 48-year-old man complained of cough, sputum and fever. Chest roentgenogram showed atelectasis of left S^<10>. Fiberoptic bronchoscopy revealed a polypoid tumor at the bifurcation of left B^<10>b+c and bronchoscopic biopsy was performed. Subsequently, the patient underwent left lower lobectomy. The resected specimen showed a polypoid tumor which was 27×23×20mm in size and protruded into the orifice of left B^<10>b. Histological examination showed low-grade malignant mucoepidermoid carcinoma. The clinical and pathological features of 43 sundar cases reported in the Japanese literature were reviewed.
