Primary renal lymphoma is a rare disease. There is still no agreement on its development primarily in this non-lymphoid organ. Some of the reported cases are questionable because of the incomplete staging of extrarenal disease. In the present study, we describe a rare case of a 73-year-old white man presenting with right flank pain. Physical examination did not reveal any peripheral lymphadenopathy or hepatosplenomegaly. An abdominal computerized tomography (CT) showed a large tumor in the right kidney with no enlarged liver, spleen or lymph nodes. On morphological and immunohistochemical examination, the tumor fulfilled the criteria of anaplastic large cell lymphoma (ALCL). A review of the literature revealed that this is the first reported case of primary ALCL of the kidney.

In this manuscript for the first time we describe the concomitant diagnosis of primary renal non-Hodgkin lymphoma (PRL) and of a papillary urothelial cancer in a patient with megaloblastic anemia. PRL is a rare disease, since the kidney is one of the extranodal organs usually not containing lymphoid tissue. The disease usually affects adults with an average age of 60 years and slight male preponderance. Flank pain is the most common presenting symptom and different histologies have been reported. A review of literature indicated that simultaneous diagnosis of PRL and papillary urothelial carcinoma of the urether, makes our case unique. The early diagnosis of both diseases allowed the eradication of the two neoplasms by nephro-ureterecthomy and by performing subsequent systemic chemotherapy.

Primary lymphoid neoplasms of the urinary tract are exceedingly rare, with only 21 cases being reported and comprising less than 5% of all primary extranodal lymphomas. We report a case of a 45-year-old man who presented with right flank pain and weight loss, and who was found to have a stricture in the right lower ureter causing ureteral obstruction. Histopathology revealed lower ureteric non-Hodgkin lymphoma, which, on further evaluation, was found to be isolated ureteric lymphoma. The patient was doing well after six cycles of R-CHOP chemotherapy. This case is being reported as a rare cause of distal ureteric obstruction.

Plasmacytomas are rare immunoproliferative monoclonal plasma cell diseases of lymphoid lineage that may present in an isolated or systemic manner. Systemic involvement is much more common than occurrences isolated to a particular organ, and for this reason, it is imperative to rule out systemic involvement for osseous and nonosseous isolated neoplasms. These neoplasms present unique challenges due to their location, extent of involvement, vague presentation, and dearth of treatment protocol. We report the case of a 69-year-old man who developed chronic kidney disease stage 4 between 2009 and 2012. Precipitous kidney failure, anorexia, fatigue, and flank pain necessitated clinical follow-up that ultimately led to thorough imaging and bilateral kidney biopsy. Protein electrophoresis, immunohistochemistry, and immunofluorescence were all consistent with bilateral renal extramedullary plasmacytomas. Treatment recommendations are often limited to prior case successes; however, chemotherapy, radiation, and surgery are the mainstay of treatment. Although surgery or combined therapy provides the best results for patients, such options are unfeasible with bilateral kidney involvement. Therefore, a chemotherapy regimen, similar to that for multiple myeloma, was determined to be most reasonable. Treatment consisted of 4 cycles of a bortezomib, cyclophosphamide, and dexamethasone regimen. Three months following chemotherapy, kidney function returned to baseline levels.
