Malignant lymphoma of the testis: report of two cases and review of the literature

Two cases of malignant lymphoma arising from the testis are reported. Case 1: A 70-year-old man presented with a painless swelling of the right scrotal contents. Right radical orchiectomy was done and histological examination revealed malignant lymphoma of the testis (diffuse lymphoma, mixed type). Bipedal lymphangiography and CT scan showed metastatic lesion in the right retroperitoneal lymph-nodes. Postoperative irradiation to the inverted Y field encompassing the para-aortic, pelvic and inguinal lymph-nodes bilaterally was given to a total dose of 5,000 rad, and treatment with anti-cancer agents was subsequently started. The patient, however, died of liver failure about 6 months after the operation. Case 2: A 74-year-old man presented with painless right scrotal swelling. Right orchiectomy was performed and the tumor histologically appeared to be anaplastic seminoma. The patient received 3,000 rad of irradiation to the retroperitoneal space. There was no evidence of metastasis, until he developed swelling of the right inguinal lymph-nodes about 5 months after the operation. Afterwards, multiple skin tumors in the legs appeared. Biopsy of the skin lesions showed metastasis of malignant lymphoma (diffuse lymphoma, large cell type). The right testis removed previously was then reviewed in detail, and primary malignant lymphoma of the testis was strongly suggested. The patient responded poorly to additional irradiation or cancer chemotherapy and died about one year and 3 months after the right orchiectomy. A statistical survey was made on 117 cases of malignant lymphoma of the testis reported in Japan and the discussion is focused on the significance of new histological classification in relation to the prognosis.

Progressive renal failure due to renal invasion and parenchymal destruction by adult T-cell lymphoma

A 43-year-old patient of occult adult T-cell lymphoma (ATL) presenting with systemic illness and progressive renal failure due to lymphomatous infiltration of kidneys is described. The striking feature observed was destructive infiltration of the kidneys, by malignant CD4 cells, virtually replacing the normal renal architecture. The diagnosis of lymphoma was made by renal biopsy. Clinical features typical of ATL were hypercalcemia, lytic bone lesions, and profound wasting and inanition. The patient died rapidly despite attempted therapy. The case illustrates the potential of ATL for direct renal parenchymal destruction.     

Renal infiltrate by a plasmocytoïd chronic B lymphocytic leukaemia and renal failure: a rare occurrence in nephropathology. A case report and review of the literature

We report the case of a 55-year-old male with renal failure as the initial manifestation of interstitial and focal infiltration of the kidneys by a small B-cell lymphoma. Since three years, this patient had a history of CLL with plasmocytic differentiation and was left untreated owing to stade A Binet classification. After chemotherapy, the lymphocytosis and the adenopathies disappear and the renal function improve. Infiltration of the kidneys by non-Hodgkin small B-cell lymphoma, including chronic lymphocytic leukaemia (CLL), is usually asymptomatic, fortuitously discovered at the time of an X-ray examination or at autopsy. Association with renal failure is extremely rare. We review the reported cases of renal failure associated with lymphomatous infiltration (13 cases of CLL and five cases of lymphoplasmocytic lymphoma kappa or lambda IgM), with the following conclusions: in most cases, renal insufficiency appears in a few months and significantly disappears after chemotherapy; the renal infiltrate is usually focal in lymphoplasmocytic lymphoma and rather massive and diffuse in CLL; the neoplastic feature of a small B-cell lympho?d infiltrate may be difficult to determine: a poorly limited, monomorphous, CD20+ CD5+ lymphoid infiltrate is lymphomatous. In case of plasmocytic differentiation, it must be looked for kappa or lambda monotypy; the type of the lymphomatous infiltrate according to the WHO 2008 classification may be difficult to determine in a small sampling of renal tissue: the renal infiltrate must be compared, if possible, with a lymph node infiltrate. Owing to its bad prognosis, mantle cell lymphoma must be distinguished from other small B-cell lymphoma like CLL/small lymphocytic lymphoma, marginal zone lymphoma and lymphoplasmocytic lymphoma.     

Acute non-dilating obstructive renal failure in a patient with AIDS

A 30-year-old male who presented with acute renal failure was found to have acquired immunodeficiency syndrome (AIDS). Although sonography and computerized tomography did not show urinary tract dilatation, obstructive renal failure was demonstrated by retrograde pyelography. Relief of obstruction(s) due to encasement of the renal pelves and ureters with histiocytic lymphoma led to immediate return of normal renal function. Although the etiology of renal failure in this patient is highly unusual, the high incidence of lymphoma in patients with AIDS should make tumor-related renal disease a consideration in all such patients with renal dysfunction.     

Simultaneous Presentation of Malignant Lymphoma of the Kidney and Multiple Myeloma of the Bone Marrow

We report a case of coexisting renal lymphoma and multiple myeloma. A 77-year-old man was referred to our hospital with a diagnosis of cancer in his right kidney. Biopsies of the renal mass and bone marrow were performed because of hyperproteinemia and biclonal gammopathy. Immunohistochemical staining and Southern blot analysis of the tumor's DNA were diagnostic for renal lymphoma. To our knowledge, this is the first time the coexistence of malignant renal lymphoma and multiple myeloma has been reported.     

Primary renal lymphoma

A 62-year-old male patient presented with right flank pain and right renal mass on CT scan. Patient left against medical advice and had nephrectomy done elsewhere. Histopathology revealed a diffuse large cell B-cell lymphoma. Patient presented again, with disseminated disease and was started on chemotherapy. Although a rare disorder, missing primary renal lymphoma as one of the causes of renal mass can lead to disseminated disease and unnecessary nephrectomy, in spite of chemotherapy being standard management.     

A case of renal malignant lymphoma

Malignant lymphoma affects any organ of the body, but is rarely found in a urological organ. We found a case of renal malignant lymphoma. A 45-year-old male, who had been operated on for primary hepatic malignant lymphoma 9 months previously, was admitted to our clinic, complaining of high fever. X-ray and ultrasonographic examinations suggested a metastatic tumor in the right kidney. Right nephrectomy was performed, and pathohistological examination revealed primary hepatic malignant lymphoma in the right kidney.     

Renal cell carcinoma in a patient with malignant lymphoma: a case report

We herein report a case of renal cell carcinoma coexisting with malignant lymphoma. A 69-year-old male complained of an obstruction of the right nasal cavity due to a solid tumor in the paranasal sinuses. A biopsy of the tumor revealed diffuse, large cell and B cell type non-Hodgkin lymphoma. At the same time, just before the patient was scheduled to receive therapy, a left renal cell carcinoma was found. He therefore underwent a left radical nephrectomy.     

Renal cell carcinoma in a patient with malignant lymphoma: a case report

A 65-year-old woman was admitted for the treatment of malignant lymphoma. Computed tomography revealed a right renal tumor. After 3 cycles of CHOP (cyclophosphamide, adriamycin, vincristine, prednisone) chemotherapy, we performed right radical nephrectomy. The histopathological diagnosis was renal cell carcinoma. After nephrectomy she was treated with 3 cycles of CHOP chemotherapy and radiation therapy. She received no adjuvant therapy for renal cell carcinoma and had no recurrence after 8 months from the nephrectomy.     

Disseminated Lymphoma Presenting as Acute Thigh Pain and Renal Failure

A 66-year-old diabetic man presented with severe right thigh swelling and pain together with acute renal failure. At autopsy, this was found to be due to disseminated high grade B cell lymphoma invading the psoas muscle and multiple organs, including the kidneys. The unique presentation of this case emphasizes the need for increased awareness of the variety of ways in which lymphoma can manifest itself.     

Isolated kidney lymphoma. Case report

Renal lymphomas, essentially secondary, are the commonest site of lymphoma in the urinary tract: 68% of cases. Apparently primary renal lymphoma is very rare and difficult to diagnose. The authors report the case of a 55-year-old patient admitted with solid tumour of the right kidney. Radical nephrectomy was performed. Histological examination revealed renal lymphoma. Postoperative assessment looking for other sites was negative. Based on a review of the literature, the authors analyse the epidemiological and diagnostic aspects of isolated lymphomas of the kidney.     

Ovarian Lymphoma and Hydronephrosis

Introduction:

Ovarian lymphoma is a rare entity, and hydronephrosis from lymphoma is even rarer. Most reports describe a laparoscopic approach to the disease, but we report a case of hydroureteronephrosis associated with ovarian lymphoma managed completely by mini-invasive techniques.

Case Report:

A 51-year-old woman was referred to us for back pain and renal colic and computed tomography scan findings of right hydroureteronephrosis and a mass in the right mesorectum and uterosacral ligament.After magnetic resonance imaging was performed, the patient underwent laparoscopic adnexectomy and ureterolysis after ureteroscopy and stenting. Histology results showed diffuse B-cell lymphoma of the ovary occluding the ureter without infiltration. The patient has undergone 6 cycles of chemotherapy.

Discussion:

This is the first report to describe ovarian lymphoma and hydroureteronephrosis managed completely by laparoscopic surgery and endoscopy. Frequency in clinical practice, differential diagnosis, and endoscopic approach are discussed. The advantages of a multidisciplinary endoscopic team are underlined.     

Surveillance of testicular microlithiasis?: Results of an UK based national questionnaire survey

Background

Renal cell carcinoma is the most common kidney tumor in adults and accounts for approximately 3% of adult malignancies. An increased incidence of second malignancies has been well documented in a number of different disorders, such as head and neck tumors, and hairy cell leukemia. In addition, treatment associated second malignancies (usually leukemias and lymphomas but also solid tumors) have been described in long term survivors of Hodgkin's lymphoma (HL), Non Hodgkin's lymphoma and in various pediatric tumors.

Case presentation

We present the case of a 66 year-old woman with abdominal pain and dyspnea. We performed a thorax CT scan that showed lymph nodes enlargement and subsequently by presence of abdominal pain was performed an abdominal and pelvis CT scan that showed a right kidney tumor of 4 × 5 cms besides of abdominal lymph nodes enlargement. A radical right nephrectomy was designed and Hodgkin's lymphoma was diagnosed in the abdominal lymph nodes while renal cell tumor exhibited a renal cell cancer. Patient received EVA protocol achieving complete response.

Conclusion

We described the first case reported in the medical literature of the coexistence between Hodgkin's lymphoma and renal cell cancer. Previous reports have shown the relationship of lymphoid neoplasms with solid tumors, but they have usually described secondary forms of cancer related to chemotherapy.     

Acute renal failure due to non-Hodgkin lymphoma infiltration of the kidneys detected by ultrasonography and confirmed by positron emission tomography

Acute renal failure (ARF) as a consequence of non-Hodgkin lymphoma infiltration of the kidneys (LIK) is an uncommon complication of non-Hodgkin lymphoma. In literature, ARF due to LIK is reported in progressive disease. A case of non-oliguric acute renal failure secondary to relapse of large B cell non-Hodgkin lymphoma primarily localized in the mediastinum is reported. LIK of both kidneys was diagnosed by ultrasonography, computer tomography scan and 18-fluorodeoxyglucose positron emission tomography. No other causes for renal failure were found. The prognosis of renal involvement in relapsed non-Hodgkin lymphoma is poor, as is demonstrated by our case.     

Proliferative glomerulonephritis associated with mantle cell lymphoma--natural history and effect of treatment in 2 cases

We describe 2 patients with mantle cell lymphoma who presented with dialysis-dependent acute renal failure and in whom the renal biopsies showed proliferative glomerulonephritis. The first patient had lymphadenopathy and the second splenomegaly, but no cause was initially identified in either case. The first patient was treated with immunosuppressive drugs, the second was given no specific therapy; renal function recovered in both. However, more than 1 year later, both again became dialysis-dependent but had also developed generalized lymphadenopathy. A diagnosis of mantle cell non-Hodgkin's lymphoma was made in both cases. The association of active lymphoma and renal disease supports a paraneoplastic mechanism for the occurrence of the glomerulonephritis in these patients. The literature describing the association between non-Hodgkin's lymphoma and glomerulonephritis is reviewed.     

Malignant lymphoma of the ureter: a case report

We report a case of malignant lymphoma (ML) of the ureter. A 71-year-old man was admitted to our hospital with the chief complaint of macroscopic hematuria. IVP showed the dilation of left ureter and renal pelvis. Retrograde pyelography showed a 2cm filling defect in the right middle ureter. From the data given, a right ureteral tumor was suspected, and we performed tumor biopsy under an ureteral scope. Since it was diagnosed not as transitional cell carcinoma (TCC) of ureter but as ML with strong inflammation, partial ureterectomy and uretero-uretero anastomosis were done. Histological diagnosis was B cell follicular center lymphoma. Because Ga-scintigraphy revealed no evidence of other involement, it was diagnosed as ML originating from ureter. ML secondarily invading the urinary tract organs is commonly found, but ML originating from the urinary tract is rare. Especially, in regards to ML originating from ureter, only 16 cases have been reported in Japan.     

Une étiologie exceptionnelle de l’insuffisance rénale aiguë : le lymphome de Burkitt

IntroductionBurkitt's lymphoma (BL) is an exceptional cause of acute renal failure (ARF). The origin of the tumor clone may be lymphoid follicles secondary to renal Epstein-Barr virus (EBV) infection. With the presentation of this clinical case, the pathogenesis, diagnostic criteria and evolution of this extremely rare affection will be discussed.ObservationA 4-year-old patient with a recent history of acute osteomyelitis of the right thigh presented an ARF without indications of post-infectious glomerulonephritis. Ultrasound showed enlarged kidneys without dilation of the excretory cavities. Diffuse interstitial infiltration of atypical lymphoid cells of medium size were noted upon renal biopsy. The tumor cells expressed antibodies against CD20, CD10, Bcl6, and Ki67 but not against Bcl2 or CD3. The search for an EBV infection was positive. A few days after diagnosis, the evolution was spontaneously fatal.Discussion/conclusionBL of the kidney is a rare condition that accounts for less than 1 % of kidney tumors, associated almost invariably with EBV infection. The diagnosis is confirmed histologically by renal biopsy and the criteria of Malbrain affirms the primitive character of the lymphoma. BL of the kidney is a diagnostic and therapeutic emergency and may be fatal.     

Primary mucosa-associated lymphoid tissue-type lymphoma arising in the kidney

Abstract:   We report a case of primary low-grade lymphoma of mucosa-associated lymphoid tissue (MALT) arising from the kidney in a 30-year-old man with an abdominal mass in the right flank detected by ultrasonography. Radical nephrectomy was performed under a preliminary diagnosis of renal cell carcinoma. The final histological diagnosis was MALT-type lymphoma. To the best of our knowledge, only five reports of primary MALT-type lymphoma in the kidney have been published in the literature so far. All cases were surgically treated and only one case went on to chemotherapy postoperatively.
