A Case of Recurred Primary Mediastinal Nonseminomatous Germ Cell Tumor Associated with Klinefelter's Syndrome

Klinefelter 증후군에 병발된 재발한 원발성 종격동 비정상피종 1예

Primary mediastinal nonseminomatous germ cell tumor associated with Klinefelter's syndrome is a rare disorder. We experienced a case of recurred primary mediastinal nonseminomatous germ cell tumor developed in a 24-year-old patient with Klinefelter's syndrome. The patient had been treated with surgery and combination chemotherapy under the diagnosis of primary mediastinal nonseminomatous germ cell tumor before. A round mass was found on the right lower lung field in the chest X-ray during follow up. The patient was diagnosed as recurred primary nonseminomatous genu cell tumor and Klinefelter's syndrome through tumor markers, peripheral blood karyotyping, and other tests including hormonal assay and was treated with combination chemotherapy and surgery again. When the patient is diagnosed as primary mediastinal nonseminomatous germ cell tumor, Klinefelter's syndrome and hematologic malignancies should be considered to be associated diseases and vice versa.
