Primary uterine lymphoma is a rare gynecologic cancer. Usually it involves rather the cervix than the uterine corpus and most of them are B-cell lymphomas. We describe a case of a 43-year old, asymptomatic patient, arrived observed for ureter dilatation due to a pelvic mass diagnosed by urography. The history of the patient, the presurgical clinical and radiological findings did not reveal any sign of uterine lymphoma. These difficulties show that at present it is not possible to make any prevention for this kind of cancer. The diagnosis of lymphoma was done at frozen section during surgery, but the final diagnosis is reached after two weeks. The patient underwent a debulking surgery of the mass, ureter cleaning with introduction of ureteral stent and a node sampling was done. The correct staging and the surgical and/or medical management of this cancer (not yet standardized) are the most important factors to improve the survival of these patients.

Non-Hodgkin's lymphomas (NHL) are common malignant tumors in children and adolescents. Among them diffuse large B-cell lymphomas (DLBCL) are relatively rare as compared to non-cleaved small cell lymphoma (mostly Burkitt's-BL) and lymphoblastic lymphoma (LL). While BL has abdominal or cervical site predilection, LL (mostly T-cell) tends to have mediastinal involvement. However, diffuse large B-cell lymphomas may involve abdomen, peripheral lymph nodes, skin, bone, other rare sites. Ureteral NHLs are extremely rare in children; however, many cases have been reported in adults. In adults the histopathology is usually follicular lymphoma. Only one case of unilateral ureter DLBCL has been reported in an adolescent in the past. Here we report a case of bilateral ureteral DLBCL to highlight the unusual presentation of NHLs and that it should be considered in the differential diagnosis of acute renal insufficiency.
