[A case report of pulmonary blastoma--biphasic pulmonary blastoma].
We report a biphasic pulmonary blastoma in a 77-year-old man. In a routine chest radiographic examination, in the left upper lung field, a massive shadow that had been entirely absent one year before was detected. The preoperative imaging films showed a 10 x 8 cm, well-circumscribed solid tumor in the upper lobe of the left lung. A preoperative clinical diagnosis of primary lung cancer was considered. The intraoperative findings were that the tumor had invaded the visceral pleura with adhesion to the parietal pleura. Left upper lobectomy with lymph node sampling was performed, and since invasion of the pulmonary artery wall was confirmed, complete removal of tumor was not possible. The postoperative diagnosis was biphasic pulmonary blastoma. The patient was treated with radiotherapy up to a limit of 50 Gy, covering the area around of the left hilum. At the latest follow-up, 1 year postoperatively, the patient was clinically and radiologically free of the disease.
