title: [Pulmonary metastatic carcinoma of the rectum growing extensively in the bronchial lumen--a case report].
abstract: A 75-year-old man secondly developed a solitary pulmonary metastatic carcinoma of the rectum, who had undergone an operation for the first pulmonary metastatic disease in the left upper division segment before three years. The second tumor was about 2.0 cm in diameter, and located in the central area of the left lower lobe. At the time of operation, the tumor was found at the roots of both the B8 and the B9 bronchi, and thus removed by the basal segmentectomy. The resected specimen showed an endobronchial growth of metastatic adenocarcinoma in both the B8 and the B9 bronchi. Especially in the lumen of the B9 bronchus, the tumor dendritically extended from the central portion to the peripheral portion. The growing pattern of the tumor was very unique, and gave us attention to the extension of resection for metastatic lung carcinoma.
