title: [Primary retroperitoneal extra-gonadal germ cell tumor].
abstract: Malignant retroperitoneal tumors are relatively rare. The most likely diagnosis by a surgeon encountering a retroperitoneal mass is metastatic disease, but primary retroperitoneal malignant disease or benign tumor should also be considered. The most common primary retroperitoneal tumors are lymphoma and sarcoma. Primary extragonadal germ cell tumors constitute 1-2% of all germ cell tumors, most of which are found in the mediastinum and retroperitoneum. We report the successful treatment of a 20-year-old man whose primary retroperitoneal extragonadal germ cell tumor was treated by chemotherapy and surgery.
