Two cases of renal lymphoma were reported. Case 1 was a 73-year-old, and case 2 was a 59-year-old female. Their chief complaint was flank pain. The findings obtained by CT and angiography were not compatible with renal cancer. The tentative diagnosis of case 1 was inflammatory disease or soft tissue tumor, and that of case 2 was renal subcapsular tumor. Histological specimen was obtained by open biopsy from case 1, and by nephrectomy from case 2. Immunohistochemical surface marker study revealed both tumors were B cell lymphoma. Chemotherapy (CHOP-Bleo, or PPA) in both cases and additional radiotherapy in case 2 markedly reduced the tumor size. Nevertheless, case 1 died 5 months later from recurrence, and case 2 died 14 months later of gastrointestinal bleeding. At autopsy, the renal subcapsular layer was infiltrated by lymphoma cells in both cases, and lymphadenopathy was not observed. Reviewing 16 cases previously reported as renal lymphoma, the capsular or subcapsular diffuse infiltration to the kidney is considered to be a characteristic feature of renal lymphoma.

A case of renal malignant lymphoma is reported. A 74-year-old man was admitted to our hospital on September 8, 1995, complainning of right flank pain, abdominal mass, and anorexia for two months. Physical examination revealed an enlarged right axillary lymph node and abdominal mass of child's head size. Computerized tomography showed a tumor (11 x 7 cm) encompassing the right kidney parenchym, and enlarged paraaprtoc lymph nodes with invasion of the left iliac creat. Transcutaneous echo-guided needle biopsy revealed that the tumor was non-Hodgkin's malignant lymphoma, diffuse large cell type, positive for B cell marker. The patient was treated with full dose of CHOP regimen. However, adriamycin was replaced with pirarubicin and the dose of the other drugs were reduced for the subsequent 4 courses because of severe leukocytopenia, thrombocytopenia, hepatotoxicity, and alopecia after the first course of the treatment. The patient showed complete remission and discharged on March 12, 1996. He, after 17 months, has no signs of recurrence. We reviewed 43 Japanese cases previously reported as renal malignant lymphoma. It is increasing in Japan especially in elderly. The 2-year survival is 26.6%.

We report a rare case in which upper ureteral rupture was the primary symptom of malignant lymphoma. A 74-year-old female visited our hospital with left flank pain. Computed tomography showed urinoma around the left kidney and retrograde pyelography showed a diffuse filling defect in the left ureter and a rupture of the upper portion of that ureter. A urine cytology specimen from the left ureter was class V, suggesting undifferentiated carcinoma or malignant lymphoma. An open laparotomy revealed a nodule on the omentum and diffuse fibrosis around both ureters, and the histopathological diagnosis was diffuse large B-cell lymphoma. The patient' s ureteral stenosis disappeared after she received six cycles of R-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone and rituximab) chemotherapy. We should be aware that malignant lymphoma can be the cause of a spontaneous ureteral rupture.

Primary lymphoma of the urinary bladder is exceedingly rare, representing 0.2% of all extranodal non-Hodgkin's lymphoma. Although Matsuno et al. and others state the most common type is mucosa-associated lymphoid tissue (MALT) lymphoma, 20% of all the primary lymphomas of the urinary bladder are considered to be high grade neoplasms; the majority being diffuse large B-cell lymphoma (DLBCL). This is a case report of a 48-year-old man that presented with hematuria, frequency, nocturia, and flank pain that was found to have high grade DLBCL. Twenty-six other cases of both low and high grade primary bladder lymphomas were selected in order to provide a thorough comparison of different treatment modalities. Of the cases reviewed, bladder lymphoma was more common in females (2:1). The average age at diagnosis was 63.9 years old (low grade: 68.7 years old, high grade: 58.8 years old). The most common low-grade neoplasm was MALT lymphoma (85.7%). For the low-grade malignancies, the most successful treatments were simple therapies (2 transurethral resection of a bladder tumour [TURBT], 1 antibiotics), solitary chemotherapy, and combination TURBT/chemo; all 3 of which achieved 100% clinical remission (CR) in the cases reviewed. The most common high grade neoplasm was DLBCL (76.9%). The most successful therapies used to treat high grade lesions were solitary chemotherapy (cyclophosphamide, duanorubacin, vincristine, prednisolone [CHOP] or ritoximab, CHOP [R-CHOP]) and combination therapies (2 radiation/CHOP, 2 surgery/CHOP). In the agreement with the current literature, this review has shown that simple therapies (TURBT) are equally as effective as aggressive treatments (chemotherapy, radiation) and should therefore be used as first line treatment in low grade tumors. For high grade malignancies, chemotherapy (R-CHOP or CHOP) alone or combination therapy (CHOP/surgery or CHOP/radiation) is recommended.

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.

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.

Primary pancreatic lymphoma (PPL) is an extremely rare disease, with only a few cases reported in the literature. Clinical manifestations of PPL are often nonspecific and may mimic other pancreatic diseases. Because of the limited experience of PPL, clinicopathological features, differential diagnosis, optimal therapy, and outcomes are not well defined. We described two cases diagnosed as PPL and confirmed by histological examination and immunohistochemical analysis. Case 1 was a young man with obstructive jaundice and upper abdominal malaise mimicking a pancreatic adenocarcinoma. A computed tomography (CT) scan revealed a diffuse heterogeneous mass in the head of the pancreas along with dilated bile ducts, no dilated pancreatic duct, no liver or splenic involvement, or evident retroperitoneal adenopathies. The patient underwent a pancreatico-duodenectomy, and the postoperative histopathology confirmed diffuse large B-cell non-Hodgkin lymphoma. Postoperatively, he received six courses of the CHOP regimen (cyclophosphamide, doxorubicin, vincristine, and prednisolone). Case 2 was an older man with left flank pain. A CT confirmed a mass with irregular margins at the tail of the pancreas and the hilum of the spleen. The mass was heterogeneous, with no clear boundary between lesions, spleen, stomach, and pancreas, with nearby blood vessels wrapped around it, and multiple enlarged lymph nodes in the abdominal cavity. A CT-guided biopsy was performed. The immunohistological findings of the specimen revealed a diffuse large B-cell lymphoma. The size of the tumor was significantly reduced after four cycles of the CHOP chemotherapy regimen. These two cases were different in clinical manifestation, location, and treatment. We reviewed the literature and discussed the clinicopathological features, differential diagnosis, optimal therapy, and outcomes of this neoplasm.
