A case of CD5-positive diffuse large cell lymphoma in a patient with autoimmune hemolytic anemia (AIHA) is reported. The patient was diagnosed with AIHA in December 1988. Three and a half years later, the patient complained of fever and left sided flank pain. Abnormal lymphocytes appeared in the peripheral blood and were positive for HLA-DR, CD5, CD19, CD20, and surface immunoglobulin (mu, lambda). The pathological diagnosis of the cervical lymphnode was non-Hodgkin lymphoma; diffuse large cell type with a starry sky-like appearance. Although the 8q24 translocation was not detected by karyotypic analysis of the peripheral blood mononuclear cells (PBMNC), Southern blot analysis revealed that the c-myc rearrangements had occurred. This case showed two rearranged bands with Eco RI, Bam HI, or Bgl II digestion, and a germline band with Hin dIII digestion using a second exon fragment of the c-myc gene as a probe. Despite intensive chemotherapy, this patient died 6 months after being diagnosed with malignant lymphoma. We discuss the c-myc rearrangements in this aggressive CD5-positive diffuse large B cell lymphoma.

Renal primitive neuroectodermal tumor (PNET) is a rare and highly malignant neoplasm of the kidney. We report the case of a 17-year-old girl with renal PNET that was complicated by Budd-Chiari syndrome. She was admitted due to abrupt left flank pain and gross hematuria. Abdominal sonography and computerized tomography (CT) disclosed a large hemorrhagic left renal mass and thrombus in the inferior vena cava (IVC). Left radical nephrectomy was performed and renal PNET with tumor rupture and tumor invasion into the IVC was diagnosed based on operative findings and histologic features. Tumor cells were positive for neuronspecific enolase, chromogranin-A, and vimentin but negative for cytokeratin, leukocyte common antigen, CD3, and CD20. The thrombus in the IVC extended into the right atrium and caused obstruction of the right and middle hepatic venous outflow, which was evident on follow-up CT scan 5 months later. The patient died due to hepatic failure and progressive cardiovascular compromise 6 months after surgery. This case demonstrates that renal PNET can be life threatening when the tumor thrombus extends into the IVC and causes hepatic outflow obstruction.

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.

Diffuse bilateral infiltration of the kidneys by lymphoma is probably the rarest cause of renal insufficiency. Moreover, acute renal failure as the initial manifestation of the lymphoma is reported only in a few cases. A 44-year-old man complaining of bilateral flank pain and weakness for 2 months was admitted with acute renal failure. Ultraonography revealed hyperechoic bilaterally enlarged kidneys and an enlarged spleen. Fat pad aspiration was negative for amyloidosis and serum protein electrophoresis was normal. Needle biopsy of the kidney and pathologic examination showed diffuse infiltration of the interstitium with lymphocytes and atypical cells. Bone marrow aspiration and biopsy were negative for malignant cells. Open kidney biopsy was performed and infiltrated cells positive for CD20 and negative for CD3 markers were observed based upon which diagnosis of diffuse large B-cell type non-Hodgkin lymphoma was made.

A 59 year old woman with a history of acute lymphoblastic leukemia in remission presented with right flank pain. An abdominal ultrasound showed mild to moderate right hydronephrosis due to obstruction, and computed tomography scan showed a bulky mass near the cervix, concerning for cervical or uterine malignancy. A Papanicolaou smear was suspicious for malignancy, and immunocytochemical stains were positive for terminal deoxynucleotidyl transferase (TdT) and cluster of differentiation (CD)-10, focally positive for CD34 and CD79a, and negative for CD3, CD20, and paired box protein-5 (PAX-5). Cervical biopsies showed an infiltrating population of cells with immunophenotype similar to the cells on cervical cytology. The cytologic and histologic workup was compatible with infiltration of the uterine cervix by recurrent precursor-B acute lymphoblastic leukemia. A bone marrow biopsy showed normocellular marrow without evidence of tumor or infiltrative disease. Complete blood count and peripheral blood smear showed no evidence of leukemic involvement. Acute lymphoblastic leukemia diagnosed on cervical Pap smear has been very rarely reported. The majority of cases of hematologic malignancy involving the uterine cervix present with vaginal bleeding. To our knowledge, only three cases of recurrent precursor-B acute lymphoblastic leukemia in the uterine cervix have been reported, two of which occurred in pediatric patients. One pediatric patient presented with vomiting and abdominal pain, and was found to have hydronephrosis on imaging. This is perhaps the first case of precursor-B acute lymphoblastic leukemia diagnosed on cervical cytology in an adult patient with hydronephrosis and without vaginal bleeding.

A 58-year-old woman was admitted to our hospital for evaluation of left flank pain. Abdominal computed tomography showed a greatly enlarged splenic tumor with a massive portal vein tumor thrombosis (PVTT). We suspected non-Hodgkin lymphoma (NHL) based on the high values of serum soluble interleukin-2 receptor and lactate dehydrogenase. Because there was no superficial lymph node enlargement, ultrasound-guided percutaneous trans-hepatic needle biopsy was performed to obtain a pathological diagnosis of PVTT, instead of a splenectomy, after the patient had provided informed consent. This procedure was thought to be less invasive than splenectomy. Histologic examination revealed CD20-positive NHL. A complete response was achieved after six courses of R-CHOP and it was confirmed by splenectomy. A PVTT due to NHL is extremely rare as compared with that due to hepatocellular carcinoma, gastric cancer, and colon cancer. However, NHL should be considered in the differential diagnosis for a patient with a PVTT, because B cell-NHL tends to have a good prognosis when rituximab combined chemotherapy is administered. We suggest that a percutaneous trans-hepatic needle biopsy may be useful for diagnosing PVTT due to NHL.
