Burkitt lymphoma (BL) is the most common pediatric cancer in sub-Saharan Africa (SSA), and also occurs frequently among adolescents and young adults (AYA), often associated with human immunodeficiency virus (HIV). Treating BL in SSA poses particular challenges. Although highly effective, high-intensity cytotoxic treatments used in resource-rich settings are usually not feasible, and lower-intensity continuous infusion approaches are impractical. In this paper, based on evidence from the region, we review management strategies for SSA focused on diagnosis, use of pre-phase, and definitive treatment...

Haemophagocytic lymphohistiocytosis (HLH) is a syndrome of dysregulated immune activity with macrophage activation that can manifest as pancytopenia, coagulopathy and other laboratory abnormalities, usually progressing to multiorgan failure and death. This report documents the rarely reported association between HLH and Hodgkin's lymphoma (HL) with simultaneous HIV and Epstein-Barr virus (EBV) and complete resolution with chemotherapy. The patient initially presented with cholestatic jaundice. He was then found to have HL associated with HLH with coexistent HIV and EBV viraemia...

The aim of the present study was to determine whether circulating soluble CD23 (sCD23) was associated with B cells non-Hodgkin's lymphomas (B-NHL). PubMed, EMBASE, and ISI Web of Science were extensively searched without language restriction. Data was extracted in a standardized data collection sheet after two reviewers scanned studies independently. The association between sCD23 and NHL was indicated as odds ratio (OR) along with its related 95% confidence interval (95% CI). Meta-analysis was conducted via RevMan 5...

BACKGROUND: Human Herpes Virus 8 (HHV8) can cause Kaposi's Sarcoma (KS) in immunosuppressed individuals. However, little is known about the association between chemotherapy or hematopoietic stem cell transplantation (HSCT), circulating HHV8 DNA levels, and clinical KS in HIV-1-infected individuals with various malignancies. Therefore, we examined the associations between various malignancies, systemic cancer chemotherapy, T cell phenotypes, and circulating HHV8 DNA in 29 HIV-1-infected participants with concomitant KS or other cancer diagnoses...

BACKGROUND: HIV-infected patients are at a higher risk to develop malignancies than general population. Although AIDS-related malignancies are a common feature of late-stage disease, patients under successful antiretroviral therapy also have an increased risk for development of non-AIDS malignancies. OBJECTIVE: To compare the frequency and characteristics of adults HIV-infected patients and general population who died of malignancies in Bahia, Brazil from January 2000 to December 2010...

Plasmablastic lymphoma (PBL) is a rare and aggressive subtype of B-cell lymphoma, which occurs typically in the oral cavity of human immunodeficiency virus (HIV)-positive patients. We report a case of a 44-year-old HIV-positive patient with a solitary polypoid mass of the left ureteropelvic junction, causing unilateral hydronephrosis and clinically mimicking urothelial carcinoma. A laparoscopic nephroureterectomy was performed, and pathological examinations revealed the mass as PBL. PBL can present in various forms, even as a polypoid mass of the upper urinary tract, and it should be considered in the differential diagnosis of any mass detected in the HIV-positive patients...

Epstein-Barr virus (EBV) reactivation causes serious diseases in immunocompromised hosts, such as acquired immunodeficiency syndrome (AIDS). We report on a case of plasmablastic lymphoma (PBL) with hemophagocytic lymphohistiocytosis (HLH).A-53-year-old Japanese man was diagnosed with PBL and AIDS. In addition to combined antiretroviral therapy, HyperCVAD (cyclophosphamide, doxorubicin, vincristine, prednisone)/high-dose methotrexate + cytarabine was initiated immediately. Partial remission was attained with chemotherapy...

Burkitt lymphoma (BL) occurs as three subtypes: endemic BL, immunosuppression-related BL and sporadic BL. Descriptive studies of BL age-specific incidence patterns have suggested multimodal peaks near 10, 40 and 70 years of age, but the risk factors for BL at different ages are unknown. We investigated risk factors for BL in the United Kingdom among 156 BL cases and 608 matched BL-free controls identified in the Clinical Practice Research Datalink (CPRD) between 1992 and 2016. Associations with pre-diagnostic body mass index, cigarette smoking, alcohol consumption, hepatitis, Epstein-Barr virus (EBV), human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS), malaria, allergic and autoimmune conditions, and prednisone use were evaluated...

Primary effusion lymphoma (PEL) is a rare B cell lymphoproliferative disorder that arises predominantly in body cavities causing malignant effusions.The incidence of PEL is very low, accounting for approximately 4% of all HIV-associated non-Hodgkin lymphomas. PEL has also been described in elderly patients and after solid-organ transplantation. It is associated in all cases with human herpesvirus 8 (HHV8). We describe a case of PEL in a 88-year-old HIV-negative woman who presented with progressive dyspnea and moderate right-sided pleural effusion without significate lymphadenopathies or other effusions...

Long-term survivors of human immunodeficiency virus (HIV) infection have been shown to have a greatly increased incidence of B cell lymphomas. This increased lymphomagenesis suggests some link between HIV infection and the destabilization of the host B cell genome, a phenomenon also suggested by the extraordinary high frequency of mutation, insertion, and deletion in the broadly neutralizing HIV antibodies. Since HIV does not infect B cells, the molecular mechanisms of this genomic instability remain to be fully defined...

A 43-year-old Malaysian man with well-controlled HIV infection on combination antiretroviral therapy presented with a six-week history of a widespread rash. The patient was otherwise well but was developing new lesions on a daily basis. Referral to Dermatology instigated punch biopsies, which revealed a diagnosis of lymphomatoid papulosis type A. This case highlights the importance of swift referral, especially in cases of spontaneous regression of symptoms, in order to obtain the correct diagnosis. In most patients, this condition tends to be chronic, with its chronicity and benign clinical course setting it apart from cutaneous anaplastic T-cell lymphoma and Hodgkin's disease, which are major entities in the histological differential diagnosis...

The introduction of combination antiretroviral therapy (cART) drastically improved performance status, immune function and life expectancy of HIV-infected individuals. In addition, incidence of opportunistic infections and of AIDS-defining malignancies declined. Nevertheless, aggressive non-Hodgkin's lymphoma still remains the leading cause of AIDS-related deaths. The availability of cART, however, significantly improved the therapeutic options for HIV-positive patients with lymphomas. Diffuse large B-cell lymphoma, Burkitt's lymphoma, or Hodgkin lymphoma have increasingly become curable diseases...

The aim of our study was to assess the association between HIV infection and cancer risk in Rwanda approximately a decade after the introduction of antiretroviral therapy (cART). All persons seeking cancer care at Butaro Cancer Center of Excellence (BCCOE) in Rwanda from 2012 to 2016 were routinely screened for HIV, prior to being confirmed with or without cancer (cases and controls, respectively). Cases were coded according to ICD-O-3 and converted to ICD10. Associations between individual cancer types and HIV were estimated using adjusted unconditional logistic regression...

BACKGROUND: Oral tongue cancer incidence has increased among whites in the United States; however, the cause remains unknown. If an infectious agent is implicated, then elevated risk would be expected among immunosuppressed individuals. METHODS: By using population-based registry linkage information from the US Transplant Cancer Match and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) Cancer Match studies, the authors examined the risk of oral tongue squamous cell carcinoma (SCC) among immunocompromised transplantation recipients and HIV-infected individuals...

Primary effusion lymphoma (PEL) is a unique form of non-Hodgkin lymphoma, usually seen in severely immunocompromised, HIV-positive patients. PEL is related to human herpesvirus-8 (HHV-8) infection, and it usually presents as a lymphomatous body cavity effusion in the absence of a solid tumor mass. There have been very few case reports of HIV-positive patients with HHV-8-positive solid tissue lymphomas not associated with an effusion (a solid variant of PEL). In the absence of effusion, establishing an accurate diagnosis can be challenging, and a careful review of morphology, immunophenotype, and presence of HHV-8 is necessary to differentiate from other subtypes of non-Hodgkin lymphoma...

Lymphoid malignancies account for the sixth leading cause of death in the US, and, although survival is improving overall, this trend is not applicable to all patients. In this review, we describe disparities in the initial presentation, treatment, and outcomes across a diverse group of lymphoma patients on the basis of gender, race, HIV status, and sexual orientation. Identifying these disparities will hopefully lead to improved outcomes in these groups of lymphoma patients in the future.

Primary CNS lymphoma (PCNSL) has been designated an acquired immune deficiency syndrome (AIDS)-defining disease since 1983 and accounts for up to 15% of non-Hodgkin lymphomas in human immunodeficiency virus (HIV) patients. The majority of HIV patients are Epstein-Barr virus (EBV)-related. The most likely etiology is ineffective immunoregulation of EBV, inducing oncogenic protein expression, and subsequent loss of apoptosis and increased proliferation of lymphocytes. PCNSL generally presents with supratentorial, single or multiple, contrast-enhancing lesions...
