title: Giant benign mesenchymoma of the mediastinum causing superior vena cava syndrome: report of a case.
abstract: The surgical resection of a giant primary mediastinal mesenchymoma causing superior vena cava syndrome is herein described. A 53-year-old man was admitted to the hospital complaining of severe dyspnea. A chest roentgenogram showed a large mediastinal mass shadow compressing the superior vena cava. At surgery, a yellow tumor measuring 27 x 25 x 12 cm and weighing 3,620 g was resected. The histological diagnosis was benign mesenchymoma. The patient's postoperative course was uneventful with a successful resolution of his superior vena cava syndrome.
