We report a rare case of Epstein-Barr virus (EBV)-positive polymorphic B-cell lymphoproliferative disorder (LPD) involving the lacrimal gland of a 28-year-old, apparently immunocompetent woman. She presented with a chief complaint of orbital swelling and tenderness and was found to have a lesion involving the right lacrimal gland and distal superior and lateral rectus muscles. Histology of the lesion revealed histiocytes with pleomorphic nuclei, reactive lymphocytes, and scattered cells that resembled the Reed-Sternberg (R-S) cells of classical Hodgkin lymphoma...

Hodgkin's lymphoma (HL) constitutes a clonal expansion of what appears to be malignant B cells. Viruses are involved in its pathogenesis, such as the Epstein-Barr virus (EBV) and human immunodeficiency virus (HIV). Since these viral infections have been shown to play key roles in the pathogenesis of HL, countries with a prevalence of HIV and EBV represent interesting population targets to study the pathogenesis of HL, linking the evolution of the disease with viral infections. Usually, patients present with late stage disease often involving the bone marrow at the time of diagnosis...

Purpose Transforming growth factor-β (TGF-β) production in the tumor microenvironment is a potent and ubiquitous tumor immune evasion mechanism that inhibits the expansion and function of tumor-directed responses; therefore, we conducted a clinical study to discover the effects of the forced expression of a dominant-negative TGF-β receptor type 2 (DNRII) on the safety, survival, and activity of infused tumor-directed T cells. Materials and Methods In a dose escalation study, eight patients with Epstein Barr virus-positive Hodgkin lymphoma received two to 12 doses of between 2 × 107 and 1...

The B-lymphotropic Epstein-Barr virus (EBV), pandemic in humans, is rapidly controlled on initial infection by T cell surveillance; thereafter, the virus establishes a lifelong latent infection in the host. If surveillance fails, fatal lymphoproliferation and lymphomagenesis ensue. The initial T cell response consists of predominantly CD8+ cytotoxic T cells and a smaller expansion of CD4+ cells. A major approach to treating EBV-associated lymphomas is adoptive transfer of autologous or allogeneic T cells that are stimulated/expanded on EBV-transformed B cells...

Loss-of-function mutations in genes encoding the signaling protein tumor necrosis factor receptor-associated factor 3 (TRAF3) are commonly found in human B-cell malignancies, especially multiple myeloma and B-cell lymphoma (BCL). B-cell TRAF3 deficiency results in enhanced cell survival, elevated activation receptor signaling, and increased activity of certain transcriptional pathways regulating expression of prosurvival proteins. A recent analysis of TRAF3 protein staining of ∼300 human BCL tissue samples revealed that a higher proportion of samples expressing the oncogenic Epstein-Barr virus-encoded protein latent membrane protein 1 (LMP1) showed low/negative TRAF3 staining than predicted...

Gray zone lymphoma (GZL) is described as sharing features with classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). However, there remains complexity in establishing diagnosis, delineating prognosis, and determining optimum therapy. Sixty-eight cases diagnosed as GZL across 15 North American academic centers were evaluated by central pathology review to achieve consensus. Of these, only 26 (38%) were confirmed as GZL. Morphology was critical to GZL consensus diagnosis (eg, tumor cell richness); immunohistochemistry showed universal B-cell derivation, frequent CD30 expression, and rare Epstein-Barr virus (EBV) positivity (CD20+, 83%; PAX5+, 100%; BCL6+, 20%; MUM1+, 100%; CD30+, 92%; EBV+, 4%)...

Immune checkpoint inhibition targeting the programmed death receptor (PD)-1 pathway is a novel treatment approach in relapsed and refractory classical Hodgkin lymphoma (cHL). Identifying patients with a high risk of treatment failure could support the use of PD-1 inhibitors as front-line treatment. Our aim was to investigate the prognostic impact of PD-1, programmed death-ligand 1 (PD-L1), and PD-L2 in the tumor microenvironment in diagnostic biopsies of patients with cHL. Patients from Denmark and Sweden, diagnosed between 1990 and 2007 and ages 15 to 86 years, were included...

Plasmablastic lymphoma (PBL) is an aggressive lymphoma, often arising in the context of immunodeficiency and associated with Epstein-Barr virus (EBV) infection. The most frequently detected genetic alteration is the deregulation of MYC gene through the translocation - t(8;14)(q24;q32). The diagnosis of PBL is often challenging because it has an overlap in morphology, immunophenotype, cytogenetics and virus association with other lymphomas and plasma cell neoplasms; further, its molecular basis remains elusive...

A 59-year-old man with an 18-year history of rheumatoid arthritis who had been treated with steroids, methotrexate, and infliximab presented with a high-grade fever, cervical lymphadenopathy, and hepatosplenomegaly. Epstein-Barr virus (EBV) hepatitis was diagnosed based on the liver histology and EBV antibody titer. The symptoms improved temporarily, but five months later, the fever, skin rash, jaundice, and thrombocytopenia relapsed. Bone marrow and liver biopsies demonstrated infiltration with Reed-Sternberg cells...

BACKGROUND: Epstein-Barr virus (EBV) causes endemic Burkitt lymphoma (eBL). EBV control was improved by magnesium (Mg2+) supplementation in XMEN, an X-linked genetic disease associated with Mg2+ deficiency, high circulating EBV levels (viral loads), and EBV-related lymphomas. We, therefore, investigated the relationship between Mg2+ levels and EBV levels and eBL in Uganda. METHODS: Plasma Mg2+ was measured in 45 women with low or high circulating EBV levels, 40 pediatric eBL cases, and 79 healthy children...

The characteristics of adult patients with chronic active Epstein-Barr virus infection (adult-onset CAEBV) are poorly recognized, hindering early diagnosis and an improved prognosis. Adult-onset CAEBV (n = 54) diagnosed between 2005 and 2015 were conducted. Adult-onset was defined as an estimated age of onset ≥15 years. To characterize the clinical features of adult-onset CAEBV, we compared them to those of pediatric-onset (estimated age of onset <15 years) patients (n = 75). We compared the prognosis of adult-onset CAEBV with that for patients with nasal-type (n = 37) and non-nasal-type (n = 45) extranodal NK/T-cell lymphoma (ENKTL)...

Objectives: Posttransplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of hematolymphoid proliferations arising in the context of chronic immunosuppression. The common and indolent B-cell lymphomas, including extranodal marginal zone lymphomas (ENMZLs) of mucosa-associated lymphoid tissue (MALT), are excluded from the category of PTLD in the current World Health Organization classification. Methods: We report a case of Epstein-Barr virus (EBV)-positive bronchial-associated lymphoid tissue (BALT) lymphoma involving the lungs of a transplant patient...

A 15-year-old boy with fever, pancytopenia, and hepatosplenomegaly was diagnosed as hemophagocytic lymphohistiocytosis (HLH). F-FDG PET/CT showed hypermetabolic foci in the liver, spleen, and bone marrow, as well as multiple FDG-avid lymph nodes, which were highly suggestive of lymphoma. Specimens from splenectomy depicted a large number of macrophages/histiocytes with hemophagocytosis of erythrocytes, without evidence of malignancy. Considering increased Epstein-Barr virus (EBV) DNA in peripheral blood and positive staining for EBV-encoded RNA in the spleen, EBV-associated HLH was confirmed...

The tetraspanin protein CD63 has been recently described as a key factor in extracellular vesicle (EV) production and endosomal cargo sorting. In the context of Epstein-Barr virus (EBV) infection, CD63 is required for the efficient packaging of the major viral oncoprotein latent membrane protein 1 (LMP1) into exosomes and other EV populations, and acts as a negative regulator of LMP1 intracellular signaling. Accumulating evidence has also pointed to intersections of the endosomal and autophagy pathways in maintaining cellular secretory processes, and as sites for viral assembly and replication...

There is increasing evidence concerning the occurrence of malignant lymphoma among people suffering from Mikulicz disease, also termed benign lymphoepithelial lesion (BLEL) and immunoglobulin G4‑associated disease. However, the underlying molecular mechanism of the malignant transformation remains unclear. The present study aimed to investigate the gene expression profile between BLEL and malignant lymphoepithelial lesion (MLEL) conditions using tissue microarray analysis, to identify genes and pathways which may be associated with the risk of malignant transformation...
