title: [Three cases of primary renal lymphoma].
abstract: Primary renal lymphoma (PRL) is very rare. In order to investigate the clinical features, diagnosis, therapy and prognosis of PRL, three cases of primary renal lymphoma diagnosed definitely and treated in our hospital in the recent ten years were reported, and their clinical features, laboratory examination, pathological observation and their therapeutics were analyzed. The results indicated that the three cases of primary renal lymphoma were all male elders. Their most common symptoms were flank pain along with abdominal mass and hematuria, etc. Because of suspicion of cancer with renal involvement, the three patients all underwent laparotomy. Histological examination showed diffuse B-cell lymphoma in the three cases, and the immunophenotype was CD20 positive in all three cases. These cases were treated with combined therapeutics, including rituximab, intermittent interferon and local radiotherapy. The 2 out of 3 cases lived for more than 5 years after therapy. In conclusion, as PRL is especially rare, and often diagnosed mistakenly, it is suggested that early and definite diagnosis and individualization of treatment for PRL patients may be possible to achieve a better therapeutic result.
