title: Retroperitoneal tumor eleven years after initial treatment of testicular cancer.
abstract: Presented is a case report of retroperitoneal tumor eleven years after orchiectomy for testicular cancer. Complete remission was achieved with combined chemotherapy and retroperitoneal lymph node dissection. Histologic examination revealed that primary testicular tumor was pure choriocarcinoma and that the retroperitoneal tumor was likely embryonal cell carcinoma without foci of choriocarcinoma. It is difficult to determine whether the retroperitoneal tumor is a late recurrence of testicular cancer of a primary extragonadal germ cell tumor.
