Background. The concomitant occurrence of a renal cell carcinoma and retroperitoneal sarcoma is extremely rare with only few cases being reported. Methods. We present a case of simultaneous renal cell carcinoma and exceptionally large size retroperitoneal sarcoma involving small intestine. Surgical resection of retroperitoneal sarcoma and simultaneous right nephrectomy were performed. Results. Patient developed recurrent and metastatic disease and underwent debulking surgery following by chemotherapy. Despite aggressive behavior of the retroperitoneal sarcomas, patient is currently (7 years after simultaneous resection and nephrectomy) recurrence-free. Conclusions. Complete surgical resection is the mainstay of therapy for both renal cell carcinoma and retroperitoneal sarcoma. We present a case of simultaneous renal cell carcinoma and exceptionally large size retroperitoneal sarcoma. Debulking surgery and chemotherapy were helpful in our case.
