Retroperitoneal Lymph Node Metastases
Many malignant tumors produce retroperitoneal nodal metastases. Retroperitoneal metastases may be secondary to squamous cell carcinoma of pelvic, urinary, or gynecological systems, gastrointestinal (GI) tract adenocarcinoma, renal cell carcinoma, and unknown origin. Up to now, we have treated 17 cases of retroperitoneal metastatic cancer, including metastatic adenocarcinoma, squamous cell carcinoma, and sarcoma. Metastatic tumors that mostly occur in the retroperitoneal lymph nodes and lymph tissue may be differentiated from primary retroperitoneal tumors that commonly arise from the connective tissue beyond the lymph nodes.
