A case of Primary Mediastinal Yolk Sac Tumor / 대한비뇨기과학회지

ABSTRACT

Extragondal germ cell tumors are rare, which develop outside of the testes, but histologically identical to primary testicular germ cell tumors. There have been much interest and controversies about their etiology, definition, treatment and care of testes. We recently experienced a case of primary mediastinal yolk sac tumor in a 16-years-old male, who was cured by intensive chemotherapy and cytoreductive surgery. Herein we report the case with review of the literature.
