[Involvement of the urogenital system in non-Hodgkin lymphoma (primary and secondary involvement)]

According to the literature the non-Hodgkin-lymphoma is involving the kidney and its capsule, the hilus of the kidney and the retroperitoneal space in some instances. Today one assumes that the disease is originating unifocally therefore one can achieve a healing or complete remission by radical surgery when one or both kidneys or a testicle are involved. Prior to this generalised disease must be ruled out. Two cases are reported where one or both kidneys were involved showing long survival time or cure. The prognosis, however, is very poor when the urogenital system is included in systemic forms of non-Hodgkin-lymphoma.
