The patient, a 53-year-old man, was referred to us with a complaint of bloody sputum by a general practitioner in March 1998. A nodular tumor was observed in the right main bronchus by bronchoscopy, and malignant cells suggesting adenocarcinoma were detected on biopsy. Since the mucosa of the right upper bronchus and truncus intermedius showed no abnormality, and also severe extramucosal invasion was not seen, a limited operation consisting of right main bronchus wedge resection and lymph node dissection was performed. Histologically, the tumor was diagnosed as a mucoepidermoid carcinoma of the salivary gland showing pleomorphism. There was no involvement of lymph nodes, and the tumor was classified as pT1N0M0, stage I A. This case is considered interesting because of difficulties in establishing the histopathological diagnosis and because of the operative technique for mucoepidermoid carcinoma of main bronchus origin.
