We report 3 cases of benign retroperitoneal schwannoma, of whom one presented with flank pain with hematuria, one presented with headache and secondary hypertension and one presented with recurrent renal colicky pain. Two patients were treated by open surgical excision of the tumor with nephrectomy of the corresponding side because the tumors were densely adhered to the kidney and one case treated by laparoscopic resection of the mass only. The diagnosis of schwannoma was established postoperatively after histopathological examination and immunohistochemistry. All patients are doing well in follow-up.
