title: Retroperitoneal Gastrointestinal Type Schwannoma Presenting as a Renal Mass.
abstract: Retroperitoneal schwannomas are extremely rare, and unreported in Urology. Often thought to be malignant from imaging the diagnosis is often delayed until Histology. We report a case of retroperitoneal schwanoma thought to be a malignant renal mass. Seventy three year old lady presented with abdominal pain. Imaging showed a mass attached to the renal pelvis thus she underwent a radical nephrectomy. Histology reported retroperitoneal schwannoma. Malignant forms are rare however treatment for these is surgical excision. Awareness of the existence of these tumors may help in avoiding unnecessary radical surgeries by opting for biopsy preoperatively.
