title: [An autopsy case of sudden death by obstruction of the pulmonary artery in cardiac rhabdomyosarcoma].
abstract: The patient was a 50-year-old man. Chest X-ray films showed a tumor shadow near the heart, which was diagnosed as carcinoma of the left lung. The patient's heart suddenly and unexpectedly stopped and he consequently died when his body was set in the right lateral position for operation on the left pulmonary tumor. A tumor measuring 6 X 3 X 3 cm was found in the region from the right ventricle to the pulmonary artery at autopsy. It was postulated that the tumor might have obstructed the pulmonary artery when the position of the patient's body was changed for surgery. A metastatic nodule was found in the left lung. The tumor was a rhabdomyosarcoma, the pleomorphic type.
