We experienced one case of combined mixed germ cell tumor and angiosarcoma metastasis to the lung within the mediastinum. He was 19-year-old male, complained of hemoptysis, coughing, purulent sputum and weight loss for 2 months prior to adimission. The patient underwent open thoracotomy, but we couldn't resect the mass completely, because of tumor encroachment on adjacent mediastinal structures. He began radiation therapy involving the right lung but had no response to therapy.
