title: [A case of chemotherapy induced necrosis of primary mediastinal germ cell tumor].
abstract: A 17 year old male with mediastinal yolk sac tumor is herein reported. His chief complaint was anterior chest pain. Chest X-ray and chest CT indicated a 8 cm diameter mass in the anterior mediastinum. Laboratory analysis revealed 2,578 ng/ml for AFP and 54% for LDH I. HCG and CEA values were normal. Yolk sac tumor was cytologically suspected on needle aspiration specimen. Combined chemotherapy with CDDP, VP16, and PEP brought the AFP and LDH 1 values down to 10 ng/ml and 27%, respectively. The diameter of the mass decreased to 6 cm. The mass was removed together with the thymus and the right upper lobe of the lung. A post operative histological examination of the mass revealed total necrosis. Nine months after the initiation of the therapy, his AFP level was within normal limits. The patient is doing well.
