Renal failure in lymphoma

Primary renal lymphoma presenting as renal failure: A case report and review of literature from 1989

BACKGROUND

Primary renal lymphoma (PRL) is extremely rare with an incidence of 0.7% among extranodal lymphomas. Occult renal lymphoma, which mimics medical renal disease and bilateral renal involvement, presents a diagnostic challenge to nephrologists and radiologists as the clinical and radiological findings are mostly non-specific or inconclusive. Acute kidney injury (AKI) is not an uncommon finding in renal infiltration due to malignant lymphoma. However, only 14% of cases are detected before death, and the low diagnostic rate may be due to the non-specific clinical manifestations of renal involvement, with only 0.5% of these cases presenting with AKI. Moreover, PRL is difficult to diagnose based on clinical, biochemical, and radiologic features, especially, in the case of bilateral diffuse involvement.

CASE SUMMARY

Herein, we report a 74-year-old woman with primary diffuse large B-cell lymphoma who presented with AKI diagnosed by ultrasound-guided needle biopsy. We also report the clinicopathologic findings of 121 PRL cases reported since 1989, by conducting a literature review of published cases.

CONCLUSION

A timely renal biopsy provides the most expedient means of establishing the diagnosis. Thus, early identification of the disease by the clinician facilitates early diagnosis toward effective treatment.

A Rare Presentation of Acute Kidney Injury in Diffuse Large B-Cell Lymphoma: A Case Report

Acute kidney injury from bilateral renal infiltration is rare in diffuse large B-cell lymphoma (DLBCL). We present the case of a 45-year-old woman with a three-month history of night sweats, weight loss, fever, and fatigue. Clinical evaluation revealed anemia, edema, cervical lymphadenopathy, and elevated blood pressure. Initial lab results indicated severe kidney injury, initially suspected to be chronic kidney disease, later ruled out. Radiological assessments confirmed mediastinal lymphadenopathy. A cervical lymph node biopsy led to a diagnosis of DLBCL. Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy improved renal function and hematological parameters. Subsequent staging CT confirmed lymphadenopathy. Close monitoring revealed a complete return to normal renal function after one month. Further follow-up was missed. This case emphasizes diagnostic complexities and the value of a multidisciplinary approach in managing complex clinical presentations.

The diagnosis and management of suspected lymphoma in general practice

With rapid advancements in diagnosis and treatment of malignancies, the gap between generalists and subspecialists continues to widen, particularly in cancers like lymphoma where the spectrum of disease varies from indolent to rapidly progressive. Prior to establishing with a hematologist/oncologist, patients must be accurately and comprehensively diagnosed and managed for lymphoma in the generalist setting. In the following manuscript, we review the common clinical presentations in which should raise concern for lymphoma. We summarize the literature regarding the role of laboratory studies including complete blood count and peripheral blood flow cytometry, the recommendations for lymph node sampling, the role and selection of imaging modalities, and ideal patient monitoring for high-risk clinical syndromes that may be encountered in lymphoma.

Renal lymphoma diagnosed on kidney biopsy presenting as acute kidney injury

Introduction:

Renal manifestations associated with hematolymphoid malignancies are known. Primary or secondary involvement of the kidney by lymphomatous infiltration has various clinical presentations. Acute kidney injury is not an uncommon finding in relation to lymphomatous interstitial infiltration proven on kidney biopsy. However, diagnosing it solely on renal biopsy remains a challenge and needs expertise and aid of immunohistochemistry as the prognosis is dismal.

Methods:

This is a retrospective study of kidney biopsy-proven cases of renal lymphoma presenting with acute kidney injury.

Results:

The study included 12 patients with ages ranging from 4 to 50 years who presented with serum creatinine ranging 2.1–9.6 mg%. Renal biopsy findings showed interstitial lymphomatous infiltrate. Two cases were diagnosed as primary lymphoma and the other 10 as secondary lymphomas. Among the 12 cases, nine were B-cell non-Hodgkin lymphoma, of which diffuse large B-cell lymphoma was diagnosed in six (50%), low-grade B-cell type in two (16.6%), chronic lymphocytic leukemia in one (8.3%), and three were T-cell-type. Two were acute T-cell lymphoblastic lymphoma and one other was a high-grade T-cell lymphoma. Four patients succumbed. The other four patients are alive; one is on chemotherapy, while two of them are on hemodialysis.

Conclusion:

Acute kidney injury as a presenting feature with lymphomatous infiltration of renal parenchyma is not uncommon. The patchy involvement makes it challenging on kidney biopsy with definitive diagnosis being made with the help of immunohistochemistry. Appropriate multidisciplinary involvement improves patient outcome.

Primary, Bilateral and Diffuse Renal Non-Hodgkin's Lymphoma in a Young Woman Suffering from Turner Syndrome

Primary renal lymphoma (PRL) is a rare form of non-Hodgkin's lymphoma (NHL) restricted to and primarily involving one or both kidneys, with no lymph node extension. It accounts for <1% of extranodal lymphomas, and descriptions in the literature are limited. Here, we describe an unprecedented case of bilateral PRL in a 44-year-old woman with Turner syndrome and discuss both diagnostic and therapeutic issues in the light of the available literature in the field. A personalized approach to this rare disease is necessary.

Light chain cast nephropathy caused by plasmablastic lymphoma of the bladder

Introduction: Plasmablastic lymphoma (PBL) is a rare form of B-cell lymphoma typically seen in patients with underlying immunosuppression such as HIV, autoimmune disease, and organ transplantation. PBL in HIV-positive patients usually originates from the gastrointestinal tract, with a predilection for the oral cavity. Bladder involvement by PBL is exceedingly rare, and cast nephropathy due to κ light chain-secreting PBL has not been reported previously. Case report: We report a patient who presented with acute kidney injury (AKI) in the setting of HIV, and was found to have a bladder tumor. Bladder pathology revealed a high-grade PBL with κ light chain restriction. Renal biopsy showed κ light chain cast nephropathy, presumably secondary to κ light chain-secreting PBL. Conclusion: Although the prognosis of PBL is poor, our patient recovered from AKI, achieved complete hematologic remission with chemotherapy, and underwent successful autologous stem cell transplant.

Clinical Presentation, Renal Histopathological Findings, and Outcome in Patients with Monoclonal Gammopathy and Kidney Disease

Monoclonal gammopathies are associated with acute and chronic kidney injury. Nephrotoxicity of the secreted monoclonal (M)-protein is related to its biological properties and blood concentration. Little is known about epidemiology, clinical manifestations, and outcome of monoclonal gammopathies in patients with kidney disease. We retrospectively collected data about demographics, clinical manifestations, and renal histological lesions of all patients (n = 1334) who underwent kidney biopsy between January 2000 and March 2017. Monoclonal gammopathy was detected in 174 (13%) patients with a mean age of 66.4 ± 13.1 years. The spectrum of monoclonal gammopathies comprised monoclonal gammopathy of undetermined significate (MGUS) (52.8%), multiple myeloma (MM) (25.2%), primary amyloidosis (AL) (9.1%), smoldering MM (SMM) (4%), non-Hodgkin lymphoma (NHL) (6.8%), and Hodgkin lymphoma (HL) (1.7%). Monoclonal gammopathy of renal significance (MGRS) accounted for 6.5% in patients with MGUS and 14.2% in patients with SMM. Evaluation of kidney biopsy revealed that M-protein was directly involved in causing kidney injury in MM (93.1%). MM was the only gammopathy significantly associated with an increased risk of kidney injury (odds ratio [OR] = 47.5, CI 95%, 13.7–164.9; P ≤ 0.001). While there were no significant differences in the progression toward end-stage renal disease or dialysis (P = 0.776), monoclonal gammopathies were associated with a different risk of death (P = 0.047) at the end of the follow-up. In conclusion, monoclonal gammopathy was a frequent finding (13%) in patients who underwent kidney biopsy. M-protein was secreted by both premalignant (56.8%) and malignant (43.2%) lymphoproliferative clones. Kidney biopsy had a key role in identifying MGRS in patients with MGUS (6.5%) and SMM (14.2%). Among monoclonal gammopathies, only MM was significantly associated with biopsy-proven kidney injury. The rate of end-stage renal disease or dialysis was similar among monoclonal gammopathies, whereas NHL, MM, and SMM showed a higher rate of deaths.

Acute Kidney Injury in the Patient with Cancer

Over the last three decades, advancements in the diagnosis, treatment, and supportive care of patients with cancer have significantly improved their overall survival. However, these advancements have also led to a higher rate of cancer-related complications. Acute kidney injury (AKI) and chronic kidney disease (CKD) are highly prevalent in patients with cancer, and they are associated with an increased risk of all-cause mortality. This bidirectional interplay between cancer and kidney, termed "the kidney-cancer connection" has become a very active area of research. This review aims to provide an overview of some of the most common causes of AKI in patients with cancer. Cancer therapy-associated AKI is beyond the scope of this review and will be discussed separately.

Primary renal lymphoma: a comprehensive review of the pathophysiology, clinical presentation, imaging features, management and prognosis

Primary renal lymphoma (PRL) is defined as a non-Hodgkin's lymphoma restricted to kidneys with the absence of extensive nodal disease. It is an exceedingly rare clinicopathological entity, accounting for 0.7% of extranodal lymphomas. Published medical literature regarding the natural history and clinical outcomes of PRL remains limited. We describe a case of a young patient who presented with left shoulder pain, continuous fever, and unexplained weight loss as atypical initial manifestations of bilateral PRL, confirmed with the standard set of investigations. Furthermore, this article reviews the literature and discusses various aspects of PRL, including pathophysiology, presentation patterns, imaging and pathological characteristics, management, and prognosis. This paper serves to provide an update and aims to enhance the understanding of PRL. Timely diagnosis and treatment are imperative to achieve improved outcomes. Clinicians should maintain a high index of suspicion in order to prevent morbidity and mortality associated with this serious disease.

Primary renal lymphoma: A population-based analysis using the SEER program (1973-2015)

Objective

Primary renal lymphoma (PRL) is defined as a non‐Hodgkin lymphoma (NHL) restricted to kidneys without extensive nodal disease. The literature on epidemiology and outcome in PRL is limited to case reports and small case series.

Methods

We utilized Surveillance, Epidemiology, and End Result database (1984‐2015) to study the demographic, clinical, and pathological characteristics of PRL. We conducted analysis to assess factors associated with overall survival (OS) and cause‐specific survival (CSS).

Results

A total of 599 (0.17% of all NHL) patients were eligible for the study. The age‐adjusted incidence was 0.035/100,000 population and is increasing. The median age was 72 years, and most of the patients were Caucasians and were males. Most of the patients had unilateral tumors, and diffuse large B‐cell lymphoma (DLBCL) was the most common histologic type. The median OS was 112 months, while median CSS was not reached. Age ≥ 60 years was the strongest independent risk factor for worse OS and CSS, while non‐DLBCL histology was associated with better OS and CSS.

Discussion

Primary renal lymphoma is a rare lymphoma with increasing incidence in more recent years. In this study, we describe demographic, clinical, and pathological characteristics of PRL and factors affecting survival among these patients.

Primary lymphomas of the intraabdominal solid organs and the gastrointestinal tract: spectrum of imaging findings with histopathological confirmation

Unlike nodal lymphoma, primary lymphomas of the intraabdominal organs are uncommon neoplasms whose diagnosis may be challenging in certain clinical circumstances. Despite this difficulty for imaging diagnosis, there are several imaging features on ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography that may suggest the correct diagnosis. The scope of this review is to describe and illustrate the imaging features of primary lymphoma of intraabdominal organs providing clues to the diagnosis, together with their pathological correlations.

Renal Dysfunction in Patients With Direct Infiltration by B-Cell Lymphoma

Background

B-cell lymphoproliferative disorders with renal involvement are relatively frequent, but remain poorly described. A kidney biopsy is usually required to detect the renal lesions that are often missed using other diagnostic tools.

Methods

We retrospectively identified 34 patients with renal lymphoma diagnosed by percutaneous kidney biopsy (PKB) at Rennes University Hospital and its affiliated hospital centers between January 1, 2004, and May 1, 2016. Clinical, biological, radiological, and histological characteristics were collected at biopsy time.

Results

The included patients had Waldenström macroglobulinemia (n = 12; 35.3%), chronic lymphocytic leukemia/lymphocytic lymphoma (n = 10; 29.5%), high-grade B-cell lymphoma (n = 6; 17.6%), and low-grade B-cell lymphoma (n = 6; 17.6%). The median follow-up was 29 months. Renal involvement led to renal function impairment in 29 patients (85.3%), among whom 20 had acute kidney injury (70%), and to nephrotic syndrome in 4 patients (11.8%). Only 13 patients (38.2%) presented morphological kidney anomalies among whom 5 showed bilateral infiltration. Histologically, interstitial infiltrate (97.1%) was the most common kidney lesion, and 9 patients (26.5%) had specific lymphomatous intraglomerular lesions. After hematological treatment (n = 29), a renal response was observed only in 8 patients (27.6%).

Conclusion

Renal involvement in the context of B-cell lymphoproliferative disorders is not uncommon. PKB is the best method to confirm this diagnosis. It should be performed early to rapidly initiate the hematological treatment to preserve kidney function.

A Rare Cause of Acute Kidney Injury: Primary Renal Lymphoma in a Patient with Human Immunodeficiency Virus

We reported a case of primary renal lymphoma (PRL) presented with non-oliguric acute kidney injury and bilateral kidney infiltrates in an individual with human immunodeficiency virus (HIV) disease. Acute kidney injury secondary to lymphoma infiltrates is very rare (less than 1% of hematological malignancy). A 37-year-old gentleman with underlying human immunodeficiency virus (HIV) disease was on combined antiretroviral therapy since diagnosis. He presented to our center with uremic symptoms and gross hematuria. Clinically, bilateral kidneys massively enlarged and were ballotable. Blood investigations showed hemoglobin of 3.7 g/L, urea of 65.6 mmol/L, and serum creatinine of 1630 µmol/L with hyperkalemia and metabolic acidosis. An urgent hemodialysis was initiated, and he was dependent on regular hemodialysis subsequently. Computed tomography renal scan showed diffuse nonenhancing hypodense lesion in both renal parenchyma. Diagnosis of diffuse large B cell lymphoma with germinal center type, CD20 positive, and proliferative index 95% was confirmed via renal biopsy, and there was no bone marrow infiltrates. Unfortunately, the patient succumbs prior to initiation of chemotherapy.

A 54-year-old male with diabetic nephropathy and suspected disseminated tuberculosis: Clinicopathologic correlation in a rare diagnosis

Tuberculosis (TB) and Non-Hodgkins lymphoma (NHL) share similar clinical and radiological features, which make diagnosis a challenge. It is often difficult to rule out a diagnosis of extrapulmonary and/or disseminated TB because of its paucibacillary nature and difficulty in accessing the involved organs. In countries with high prevalence of TB like ours, empirical antitubercular treatment (ATT) is started, and the patient is followed up closely for response. We present a rare case of a 54-year old diabetic male who was suspected to be a case of disseminated TB but had a rapid downhill course despite ATT. A postmortem revealed features of a rare, aggressive T-cell NHL masquerading as disseminated TB.

Diffuse large B-cell lymphoma presenting as bilateral renal infiltration leading to acute kidney injury

Acute kidney injury (AKI) because of bilateral renal infiltration is an uncommon presentation of diffuse large B-cell lymphoma (DLBCL). A 52-year-old man presented to our institution with AKI and complaints of fatigue. Ultrasonography revealed a large, 15 cm granulomatous mass arising from the bilateral kidneys. The mass was biopsied laparoscopically, and histopathological analysis revealed evidence of DLBCL. The patient subsequently underwent R-CHOP therapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). Chemotherapy resulted in a rapid decrease in mass size and improvement in kidney function. However, after five courses of R-CHOP, relapse was observed in the central nervous system, and the patient died 220 days after the initial onset of AKI. Post-mortem analysis of renal tissue confirmed the initial diagnosis of DLBCL-associated renal infiltration. To our knowledge, this is the first report of DLBCL presenting as bilateral renal infiltration and AKI.

Antineutrophil cytoplasmic antibody-positive pauci-immune glomerulonephritis associated with mantle cell lymphoma

Renal involvement in non-Hodgkin lymphoma, especially mantle cell lymphoma (MCL) is rare. A 77-year-old man presented with acute kidney injury (AKI), which rapidly progressed to dialysis dependence. Kidney biopsy revealed patchy B-cell lymphocytic aggregates in the interstitium, which were positive for cyclin D1, consistent with atypical CD5-negative MCL as confirmed by the detection of translocation t(11;14) by FISH. Crescents were noted in 3 of 26 glomeruli; while PR-3 antineutrophil cytoplasmic antibody (ANCA) positivity and negative immunofluorescence suggested an additional pauci-immune (rapidly progressive) glomerulonephritis pattern of injury. Patient received chemotherapy (cyclophosphamide, vincristine, and prednisone), which improved his renal function and allowed for discontinuation of hemodialysis. However, he died from pulmonary hemorrhage 8 months after initial presentation. This is the first reported case of a patient with coexistence of renal MCL infiltration and ANCA-positive pauci-immune glomerulonephritis.

Primary Renal Lymphoma - A Case Report and Review of Literature

Primary Renal Lymphoma (PRL) is rare and its existence has been called into question due to the absence of lymphatic tissue within renal parenchyma. Non-specific abdominal pain with mass in the lumbar region and otherwise unexplained renal failure is the most common presentation. Almost all patients eventually develop extrarenal lymphomatous disease and few patients survive beyond one year. Surgical treatment is rarely feasible as primary modality of treatment since the tumour often encases major vessels and surrounding organs necessitating major resection. Instead, an attempt can be made to downstage the tumour with chemotherapy before attempting surgery. Here we present a case of primary renal Non-Hodgkins Lymphoma (NHL) which was treated with chemotherapy but the patient succumbed to disease before the third cycle.

Lymphoblastic lymphoma presenting as bilateral renal enlargement diagnosed by percutaneous kidney biopsy: Report of three cases

Renal involvement by lymphoma can be a diagnostic challenge. Acute kidney injury (AKI) is an unusual manifestation of lymphomatous infiltration in the kidneys. We report three cases of lymphoblastic lymphoma, a very rare form of lymphoma, presenting with AKI and bilateral enlargement of kidneys, diagnosed by percutaneous kidney biopsy. Lymphomatous infiltration should be suspected with such clinical presentation. Kidney biopsy is a valuable diagnostic tool, to establish the correct diagnosis and subtype of lymphoma for timely initiation of therapy for these aggressive hematological malignancies.

Baseline renal function as a prognostic indicator in patients with newly diagnosed diffuse large B-cell lymphoma

Background

The association between baseline renal impairment (RI) and the prognosis of diffuse large B-cell lymphoma (DLBCL) was previously not defined. The aim of this study was to evaluate the prognostic value of RI in patients with DLBCL treated with three-weekly rituximab plus cyclophosphamide, Adriamycin, vincristine, and prednisolone immunochemotherapy (R-CHOP21).

Methods

Patients with newly diagnosed de novo DLBCLs treated with ≥1 cycle of R-CHOP21 were analyzed retrospectively. Pretreatment blood samples were collected and the glomerular filtration rate (GFR) was calculated. RI was defined by a GFR of <60 mL/min/1.73 m² according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula.

Results

Of the 185 patients enrolled in the present study, 19 patients (10.3%) had RI. The reasons for baseline RI were pre-existing CKD (N=5), acute kidney injury due to either obstruction (N=2) or electrolyte imbalance (N=2) related to DLBCL, and undefined causes (N=10). Patients with baseline RI showed inferior overall survival (OS) compared to those without RI (P<0.001). In multivariate analysis, RI was identified as an International Prognostic Index (IPI)-independent prognostic indicator. A baseline hemoglobin level of <10 g/dL and the presence of RI effectively discriminated a portion of the patients with far inferior event-free survival and OS among the patients having high or high-intermediate risk cancers according to either the standard- or the National Comprehensive Cancer Network-IPI.

Conclusion

Pretreatment RI was an independent prognostic marker for inferior OS in patients with DLBCL treated with R-CHOP21 immunochemotherapy.

T-cell lymphoma masquerading as extrapulmonary tuberculosis: case report and review of literature

It is often difficult to establish confirmatory diagnosis in cases of extrapulmonary tuberculosis (TB) because of its paucibacillary nature and difficulty in accessing the involved organs. In several cases, empirical anti-tubercular treatment is started, and the patient is followed-up closely for response. In countries with high prevalence of TB, it is a reasonably good strategy and works most of the times. However, catastrophe may occur when aggressive lymphomas masquerade as TB.

Acute renal failure in a patient with mantle cell lymphoma

Mantle cell lymphoma is a rare form of B-cell lymphoma. We present a 54-year-old gentleman with mantle cell lymphoma. It was diagnosed based on the demonstration of B-cell antigens CD20 and CD5. It was further confirmed by demonstration of overexpression of cyclin D1 on these atypical lymphocytes in the immunohistochemical staining. He also had acute renal failure and proteinuria. Renal biopsy revealed crescents and lymphomatous infiltration of tubulointerstitium. The presence of infiltrating cells with similar markers in both the lymph node and the kidney confirmed the infiltration of kidney with lymphomatous cells. Our present patient, after a thorough literature search, is found to be the second one with a glomerular lesion and tubulointerstitial infiltration by malignant lymphoma cells.

Polycythemia, increased erythropoietin levels in a patient with renal lymphoma

A young male presented to our clinic with 3 months history of shortness of breathness and progressive distension of abdomen. On investigations, patient had renal failure, polycythemia and nephromegaly. A diagnosis of non-Hodgkin's lymphoma was made on renal and lymph node biopsy. Serum erythropoietin concentrations were physiologically inappropriate. – Erythropoietin immunohistochemistry on renal tissue samples demonstrated positive staining for tumor cells. This patient was managed as a case of infiltrative lymphoproliferative disorder with kidney involvement having polycythemia owing to paraneoplastic Erythropoietin production and possibly local hypoxia produced by tumor cells. With maximum efforts, we could not find such an association in the literature.

A pediatric renal lymphoma case presenting with central nervous system findings

In pediatric patients renal lymphoma frequently presents in the form of multiple, bilateral mass lesions, infrequently as a single or retroperitoneal mass, and rarely as diffuse infiltrative lesions. In patients with apparent central nervous system involvement close attention to other physical and laboratory findings are essential for preventing a delay in the final diagnosis. Herein we present a pediatric patient with renal lymphoma that presented with central nervous system findings that caused a delay in diagnosis.

CONFLICT OF INTEREST

None declared.

Primary renal lymphoma: long-term results of two patients treated with a chemotherapy + rituximab protocol

Primary renal lymphoma (PRL) is a rare disease of which the etiology and pathogenesis remain controversial, and there is currently no standard treatment for it. We present the results of a long-term followup of two patients who were diagnosed with PRL and treated with cyclophosphamide, adriamycin, vincristine, prednisolone and rituximab (CHOP + R) regimen. Both patients reached a complete response, and there is no evidence of recurrence after 4.5- and 5-year followup periods. Based on our experience and other recently published studies, we recommend the combination of CHOP + rituximab as the elective treatment for this disease. To our knowledge, this is the longest followup period with a complete response that has been reported with this modality of treatment.

[Acute renal failure due to malignant lymphoma infiltration]

We present two cases of renal lymphoma revealed by acute renal failure (ARF), which remains a rare clinical entity. Case 1 was a 29-year-old man with an ARF. The diagnosis was a primitive kidney immunophenotype B lymphoma. The patient died after three courses of chemotherapy due to rapid spread lymphoma. The second case was a high-grade renal lymphomatous infiltration, with an unusual computer tomography image of two large kidneys compressing the stomach. Death happened early before initiating therapy. In both cases the diagnosis has been established by renal pathology. Early diagnosis is a key component of therapeutic success, however, the rapid spread of lymphoma worsened renal and vital prognosis.

[Bilateral primary renal Burkitt lymphoma presenting with acute renal failure]

We report the case of a 12 year-old girl who presented with acute renal failure with massive infiltration in both kidneys due to a Burkitt lymphoma that was diagnosed by percutaneous renal biopsy. This case fulfilled all the diagnostic criteria of Malbrain et al. to be considered as primary renal non-Hodgkin lymphoma. We discuss the differential diagnosis with other processes that present with acute renal failure and bilateral nephromegaly, and the mechanism by which renal failure occurs. It should be emphasised that this patient showed clinical symptoms compatible with rheumatic disease at diagnosis. The possibility of joint and muscle problems should be considered as a sign of onset of hematopoietic disease.

Acute kidney injury requiring dialysis: a very unusual presentation of non-Hodgkin's lymphoma

Acute kidney injury due to lymphomatous infiltration of the kidneys is uncommon, and it is rarely the initial manifestation of the lymphoma. Here, we present a case of lymphomatous infiltration of the kidneys resulting in acute kidney injury requiring dialysis, as the initial presentation of non-Hodgkin’s lymphoma. Renal biopsy established the diagnosis, and renal function completely recovered after chemotherapy.

Acute Renal Failure Secondary to Small Cell Lung Cancer with Tumor Infiltration of the Kidneys

Acute renal failure secondary to tumor infiltration of the kidneys is uncommon and largely described in patients with lymphoma or leukemia. We report a 64-year-old man previously diagnosed with limited stage small cell lung cancer who presented with acute renal failure (ARF). Renal imaging showed bilateral enlargement with features suggestive of an infiltrative process. A kidney biopsy established the diagnosis of metastatic small cell lung cancer with diffuse renal parenchymal infiltration. This case emphasizes the rare potential for cancers to metastasize to the kidneys, which can result in ARF. Early recognition of this cause of ARF is crucial, in particular, when the tumor is amenable to chemotherapy or irradiation.

Lymphomas diagnosed by percutaneous kidney biopsy

BACKGROUND

Occult renal lymphoma clinically mimicking renal medical disease constitutes a diagnostic challenge to nephrologists, radiologists, and renal pathologists. The clinical and radiological findings, mostly nonspecific or inconclusive, seldom obviate the need for a kidney biopsy.

METHODS AND RESULTS

We report 5 new cases of diffuse bilateral renal lymphoma diagnosed by percutaneous kidney biopsy, all presenting with acute renal failure (ARF) of unknown cause. Three cases showed an interstitial and 2 an intraglomerular/intravascular type of lymphomatous infiltration. All tumors were of B-cell lineage. Our cases add to 50 similar cases reported since 1980. Considering all 55 cases together, 39 (87%) of the 44 cases with interstitial and 5 of 11 (45%) of those with intraglomerular lymphoma presented with ARF. In contrast, 5 of 10 cases with intraglomerular but none with interstitial infiltration presented with nephrotic range proteinuria. All but 2 cases (95%) with ARF and interstitial lymphoma but none with ARF and intraglomerular lymphoma showed bilaterally enlarged kidneys. Signs of extrarenal lymphomatous involvement were detected in 24 cases (44%) at the time of kidney biopsy or shortly thereafter. However, in only 10 cases (18%), all with interstitial lymphoma, was a tumor suspected prior to biopsy, mainly based on radiographical evidence of enlarged kidneys.

CONCLUSION

Both types of diffuse bilateral renal lymphoma may clinically mimic renal medical disease. ARF in interstitial and in intraglomerular lymphoma may be due to increased intrarenal pressure and intraglomerular obstruction, respectively. Percutaneous kidney biopsy provides the most expedient means of establishing the diagnosis. Differential diagnosis includes interstitial nephritis and proliferative glomerulonephritis.

CT of renal lymphoma in children

OBJECTIVE

The purpose of this study was to determine the incidence and to describe the CT findings of renal lymphoma in children.

CONCLUSION

Renal lymphoma was seen in 11 children, most commonly due to non-Hodgkin's lymphoma (n = 10, 91%) and Burkitt's subtype (n = 5, 45%). Multiple bilateral masses were the most common CT appearance. Less common presentations included focal solitary masses or an engulfing mass. Retroperitoneal lymph node enlargement and other organ involvements were common associated findings. Five of six patients with renal involvement at initial diagnosis have had cures or remissions. Therefore, renal involvement at the time of initial diagnosis with lymphoma does not portend a poor prognosis.

Kidney involvement and renal manifestations in non-Hodgkin's lymphoma and lymphocytic leukemia: a retrospective study in 700 patients

Renal involvement as part of systemic lymphoma (LY) is quite frequent, however, primary extranodal renal non-Hodgkin's lymphoma (NHL) is extremely rare, and only about 65 cases have been reported in the world literature. In a retrospective study of renal manifestations in 700 patients with documented LY and chronic lymphocytic leukemia (CLL) seen at our hospital during 1986-95, 83 patients had signs of acute renal failure. Only five of these had proven renal infiltration, but none of them satisfied the criteria for primary renal LY. Glomerulonephritis (GN) has also rarely been reported in association with LY and CLL, and only 37 glomerular lesions in NHL and 42 in CLL have been documented, respectively. GN may precede, coexist, or follow the diagnosis of LY by several years. Of the 42 cases of CLL reported worldwide, 36 had nephrotic syndrome. Renal failure was seen in about one third. The most common glomerular lesion reported is membranoproliferative GN, followed by membranous GN. In our study, we found only five biopsy-proven cases with GN amongst the 700 patients seen. In this report we also briefly describe some rare interesting associated renal syndromes in CLL and NHL.

Acute renal failure as presentation of a Burkitt's lymphoma

Acute renal failure due to diffuse renal infiltration is rarely the presenting manifestation of non-Hodgkin's lymphoma. We report a patient with acute renal failure secondary to diffuse bilateral renal infiltration by a Burkitt's lymphoma. The presence of bilateral renal enlargement, an elevated serum lactate dehydrogenase (LDH), and lymphopenia should suggest the diagnosis, which can be confirmed by renal biopsy.

Renal failure due to T-cell mediated lymphocytic vasculitis: an unusual complication of B-cell chronic lymphocytic leukemia

Vasculitis is an uncommon paraneoplastic syndrome, and acute renal failure is an unusual presentation of leukemia. We report a case of B-cell chronic lymphocytic leukemia that presented with acute renal failure caused by biopsy-proven lymphocytic vasculitis that subsequently was shown to be T-cell-mediated and systemic at autopsy.

Association of primary renal non-Hodgkin's lymphoma with mesangioproliferative glomerulonephritis

A 27-year-old male developed nonoliguric renal failure. Renal biopsy of the left kidney showed infiltration by a diffuse large-cell non-Hodgkin's lymphoma (NHL). Laparoscopy, CT scans of the abdomen and thorax, and bone-marrow biopsy revealed no further manifestations of lymphoma. Primary renal NHL was diagnosed. The patient attained complete remission with cyclophosphamide, adriamycin, vincristine, and prednisone (CHOP) chemotherapy and remained disease-free for 13 years. Eight years after his first presentation, the patient developed acute oliguric renal failure with nephrotic syndrome. Mesangioproliferative glomerulonephritis was diagnosed in a biopsy of the left kidney. Chronic hemodialysis was required until cadaver kidney transplantation was successfully performed 5 years later. Although the association of NHL and glomerulonephritis has been described several times before, to our knowledge this is the first report of glomerulonephritis in primary renal lymphoma.

A case of non-Hodgkin's lymphoma presenting with polyuria and acute renal insufficiency

A case of non-Hodgkin's lymphoma presenting with polyuria, enlarged kidneys, and renal insufficiency is reported. The diagnosis was made by percutaneous needle biopsy of the kidney. Renal failure reversed and the kidneys regressed in size on exhibition of the first cycle of chemotherapy. The rarity of polyuria at presentation, the role of renal biopsy in the diagnosis, and the response of renal failure to specific chemotherapy are discussed.

B-cell lymphoma presenting as infiltrative renal disease

Acute renal failure is rarely the presenting manifestation of non-Hodgkin's lymphoma. Of the reported cases of renal insufficiency secondary to diffuse renal infiltration with lymphoma, few have presented with acute renal failure. We present a patient with acute renal failure secondary to diffuse bilateral renal infiltration by a B-cell non-Hodgkin's lymphoma. The findings of an elevated serum lactate dehydrogenase (LDH), lymphopenia, and homogenous bilateral renal enlargement on computed tomographic (CT) imaging were important in suggesting the diagnosis of primary renal lymphoma. Renal biopsy with immunohistochemical and ultrastructural analysis was instrumental in confirming this diagnosis.

Primary renal lymphoma

Lymphomatous involvement of the kidneys is a common manifestation of systemic non-Hodgkin's lymphoma but associated renal dysfunction is uncommon. In contrast, lymphoma originating within the kidneys is a rare event. We report a case of primary renal lymphoma presenting with renal insufficiency and hypertension in a 10-year-old boy.

Diagnosis and characterization of non-Hodgkin's lymphoma in a patient with acute renal failure

This case illustrates the relatively rare occurrence of malignant lymphoma presenting as acute renal failure due to renal parenchymal infiltration. To our knowledge, it is the first report in which the phenotype of a non-Hodgkin's lymphoma was established using renal biopsy tissue. The dangers of treatment of renal lymphoma in the patient whose disease has not been adequately characterized have been noted by Coggins.

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.

Primary renal lymphoma presenting as acute renal failure

Diffuse bilateral infiltration of the kidneys by lymphoma cells is a rare but well-documented cause of acute renal failure (ARF). Only 51 such cases have been reported, 15 of which had ARF as the initial presentation of lymphoma. The clinical and pathologic features of these 15 cases and of two additional cases reported herein are reviewed. The diagnosis should be suspected in a patient with ARF, bilateral enlargement of the kidneys, minimal proteinuria, nonspecific findings on urinalysis, and absence of features of allergic tubulointerstitial nephritis. Renal imaging techniques may suggest the possibility of lymphomatous infiltration, but only renal biopsy or autopsy can provide a definitive diagnosis. Although modern chemotherapy and/or radiation therapy usually leads to a dramatic normalization of renal function, almost all patients eventually die of widespread recurrent lymphoma, despite the absence of clinical or pathologic involvement of the kidneys at the time of death.

Renal failure due to lymphomatous infiltration of the kidneys. Report of three new cases and review of the literature

Three new cases of renal failure due to lymphomatous infiltration of the kidneys are described and the clinical features of 14 similar patients in the literature are reviewed. The diagnosis of renal failure secondary to lymphomatous infiltration was made by ruling out other causes of renal failure and demonstrating prompt improvement in renal function after systemic chemotherapy or local irradiation of one or both kidneys. Histiocytic lymphoma was the most common underlying disease. In the setting of diffuse lymphoma with other causes of renal failure reasonably excluded, radiographic demonstration of enlarged kidneys without obstruction suggests the need for intensive combination chemotherapy in most cases.

Urinary cytodiagnostic abnormalities in 50 patients with non-Hodgkin's lymphomas

Urinary cytodiagnostic evaluation was performed on 50 consecutive patients with non-Hodgkin's lymphomas. In 14 patients (28%) the urine sediment contained characteristic lymphoma cells. The groups with or without a positive urine cytology were comparable with respect to type of lymphoma, stage and course of disease, and recent treatment with chemotherapy. However, those with a positive urine cytology were more likely to have clinical evidence of kidney disease (43% vs 8%), although this was rarely attributed to disseminated lymphoma. In fact, in three patients, a positive urine cytology was the sole or presenting evidence for disseminated lymphoma. Although the groups with or without a positive cytology were similar with regard to physicochemical urinary findings, there were marked differences in the frequency of microscopic abnormalities. All patients with a positive cytology had evidence of renal parenchymal necrosis, renal tubular injury, or pathologic cast formation as compared with only 56% of those with a negative cytology. Thus, urinary cytodiagnostic evaluation may provide an important adjunct in the staging and evaluation of patients with malignant lymphomas.

Acute Anuric Bilateral Ureteral Obstruction in Malignant Lymphoma

Two cases of bilateral ureteral obstruction in malignant lymphoma are reported. In one case, primary infiltration of the ureters by Hodgkin's disease was demonstrated, while in the other the obstruction was due to ureteral compression by enlarged lymph nodes. The diagnostic procedures and the management of such cases are discussed.

Renal failure due to lymphomatous infiltration of the kidneys

An unusual case of lymphomatous infiltration of the kidneys presenting as uremia of unknown cause is described. The diagnosis was established by renal biopsy. The severe renal impairment in this patient proved to be almost completely reversible by treatment with chemotherapy.
