[Case contribution on the clinical aspects and therapy of retroperitoneal xanthofibrogranuloma].

The retroperitoneal xanthofibrogranuloma is a rare disease with still unclear etiology. The clinical symptoms are uncharacteristic and in connection with laboratory-chemical and radiological findings let us first think of a malignoma. According to our opinion the therapy of choice is the radical as possible removal of the xanthofibrogranuloma, which is in most cases only possible with simultaneous nephrectomy. A superradicality is not necessary. The prognosis is good.
