title: A retroperitoneal gastrointestinal schwannoma presenting as a perinephric mass.
abstract: There are less than 100 cases of retroperitoneal schwannoma reported in the world literature. These are differentiated from gastrointestinal schwannomas found in the gastrointestinal tract. A case of a rare retroperitoneal gastrointestinal schwannoma presenting as a perinephric tumor is described. Treatment of such masses is local excision and final diagnosis is from histopathology.
