title: [A case of early mucoepidermoid carcinoma arising from the left upper bronchus and presenting the flow-volume curve as a manner of extra-thoracic airway obstruction].
abstract: A 23-year-old female was admitted with dyspnea, dry cough, and rhonchi. No abnormalities were detected on chest roentgenogram. Fiber-bronchoscopy revealed a polypoid lesion with necrotic material occluding the left main bronchus. The pathological diagnosis of the biopsied material was low grade mucoepidermoid carcinoma. Following tumor reduction by Nd-YAG laser, it was clear that the primary lesion originated from the left upper bronchus. Sleeve lobectomy was performed, and the tumor was proved to be early lung cancer of hilar type with extension limited to the bronchial wall.
