Paraneoplastic glomerulopathy secondary to retroperitoneal sarcoma: A case report

Glomerulopathy is a rare form of paraneoplastic disease. We present the second reported case of paraneoplastic glomerulopathy due to a retroperitoneal sarcoma. The patient presented with generalized edema and nephrotic syndrome. CT scan showed two large retroperitoneal masses. One large retroperitoneal mass was resected. Post‐operatively, she developed kidney failure and biopsy showed minimal change disease. With steroid therapy, patient's symptoms went into remission. We hypothesize that minimal change paraneoplastic glomerulopathy developed due to damage from cytokines released from a T‐cell mediated response to the malignancy. J. Surg.
