Abstract
A 62 year-old, female was admitted with hemoptysis. An abnormal shadow was recognized in the left middle lung field on chest X-ray film. A glossy tumor with partial bleeding at a site about 1cm from the orifice of B^3 was observed by fiberoptic bronchoscopy. Resection of the left upper lobe and S^6 was conducted, and the postoperative course was good. Most adeno carcinomas of the lung are located in the peripheral region of the lung. In this case, the tumor occurred from the central bronchus and clearly showed protrusion into the bronchial lumen. It was histologically diagnosed as a well-differentiated papillary adenocarcinoma occurring in the central region of the lung.
