[Extragonadal germinal tumors of retroperitoneal localization].
Extragonadal germ cells tumors can arise primarily in the retroperitoneum. It has been suggested that these neoplasms might be metastasis from an occult testicular lesion which would have regressed later. We report our experience with seven retroperitoneal germ cell tumors without testicular involvement. The most frequent symptoms were lumbar or abdominal pain and paraneoplastic syndrome. Abdominal palpable mass was noticeable in 85% of patients. We point out the computerized tomography and echography as the most sensitive exploration for diagnosis. The confirmation of retroperitoneal tumor was achieved preoperatively in all cases. Surgical and chemotherapy treatment was performed. Radiotherapy was employed in two cases. The mean survival was 9.5 months (6-24 m.). Retroperitoneal lymphadenectomy after chemotherapy has not improved the survival. Relapses of the diseases were noticed after and apparently partial or complete response to chemotherapy.
