To retrospectively analyze the prognostic significance of plasma Epstein-Barr virus (EBV) DNA in 122 patients with diffuse large B cell lymphoma (DLBCL). Plasma EBV DNA positivity was related to advanced disease stage (P=0.030), B symptoms (P=0.004) and elevated serum lactic dehydrogenase (LDH) (P=0.001). Furthermore, univariate analysis indicated that plasma EBV DNA level was associated with worse overall survival (OS) (HR=0.223, 95%CI 0.096-0.518, P<0.001) and worse progression free survival (PFS) (HR=4...

Non-Hodgkin's lymphoma (NHL) is a common malignancy of childhood; however, a lung primary presentation is an uncommon finding, as is finding an association with the Epstein-Barr virus (EBV). We report the case of a 23-month-old female who developed EBV-associated diffuse large B-cell lymphoma (DLBCL) that was initially thought to be pneumonia. Extensive tissue necrosis, focal angioinvasion, and angiodestruction were observed. She was refractory to various therapy regimens, subsequently developed DLBCL in the central nervous system, and eventually expired...

EBV-positive mucocutaneous ulcer (EBVMCU) is a newly recognized provisional entity, included in mature B-cell neoplasm in the latest 2016 World Health Organization Classification. It has a self-limited growth potential with a high predilection for oral cavities, and occurs in age-related or iatrogenic immunodeficiency with indolent clinical courses. However, it shares histological features with EBV-positive diffuse large B-cell lymphoma (DLBCL), and this often leads to diagnostic challenges and controversies in patients with an oral EBV-positive B-cell neoplasm...

MYC is the proto-oncogene classically associated with Burkitt lymphoma (BL) located at chromosomal locus 8q24. Rearrangements of MYC are seen in nearly 100% of BL but have been reported in 3-16% of diffuse large B-cell lymphomas (DLBCLs). Rearrangements of MYC are tested for by flourescence in situ hybridization (FISH). In this study, we compared immunohistochemistry (IHC) using a monoclonal antibody directed against the human Myc protein to the current method, FISH. 31 cases were identified that had been tested for MYC rearrangements by FISH over 27 months with heterogeneity in the diagnoses: 5 BL; 10 DLBCL; 3 B-cell lymphoma unclassifiable between DLBCL and BL; 5 B-cell lymphoma not otherwise specified; 1 EBV-related B-cell lymphoma; 1 composite CLL/SLL-large cell lymphoma; and 6 designated as high-grade or aggressive B-cell lymphoma...

CD20-negative diffuse large B-cell lymphomas (DLBCLs) constitute a rare and heterogeneous group of aggressive lymphomas. Known well-documented variants include plasmablastic lymphomas, primary effusion lymphomas, anaplastic kinase-positive large B-cell lymphomas, and large B-cell lymphomas arising in human herpesvirus 8 (HHV8)-associated multicentric Castleman disease. They impose diagnostic challenges for pathologists and therapeutic confrontations for clinicians. CD20 loss in B-cell lymphomas is a well-known phenomenon after rituximab therapy...

While the World Health Organization included Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) as a provisional entity of a lymphoma occurring in older individuals without any known immunodeficiency in 2008, it has since been recognized that this entity may occur in younger individuals. As a result, the 2016 revision has substituted the modifier "elderly" with "not otherwise specified" (NOS). The NOS highlights that there are more specific entities with neoplastic EBV-positive large B cells such as lymphomatoid granulomatosis...

Primary cutaneous large B‑cell lymphomas (PCBLT), EBV-positive large B‑cell lymphomas, not otherwise specified (EBV+ DLBCL, NOS), and primary cutaneous intravascular large B‑cell lymphomas (PCIVLBL) are recognized as cutaneous lymphomas with intermediate to poor prognosis. Differentiation from indolent B‑cell lymphomas or other pathologies of the skin can be complex, both clinically and histologically, but vital for the outcome of the patient. The combination of immunotherapy and polychemotherapy regimens, such as R‑CHOP, has led to significant improvements in prognosis, especially in diffuse large B‑cell lymphomas...

Cases of B-cell lymphoma over an 8-year interval with diagnosis of EBER positivity were retrieved from archives and reviewed for classification and pattern of Epstein Barr Virus (EBV) expression. Of 46 cases that were EBV early RNA (EBER)+ by in situ hybridization staining, 7 had nonuniform staining among the neoplastic cells. Four of those cases showed a uniform admixture of EBER+ and EBER- tumor cells, compatible with the prevailing theory of episomal EBV loss with cell replication. Three cases of lymphomas showed a partial and zonal pattern and other features suggest that EBV infection occurred after the lymphoma was already established...

AIMS: Primary cardiac lymphoma (PCL) is a rare neoplasm. PCL is fatal, unless it is diagnosed and treated early. Recently, a small number of cases of diffuse large B cell lymphoma (DLBCL) arising within atrial myxoma have been reported in immunocompetent patients and showed aggressive histological features but an indolent clinical behaviour. METHODS AND RESULTS: We present four unusual cases of Epstein-Barr virus (EBV)-positive DLBCL arising within atrial myxoma with detailed clinical, histological, immunophenotypical and genotypical features in immunocompetent patients, and review the literature for 11 similar cases...

Epstein-Barr virus (EBV)-mediated B cell transformation is achieved predominantly through the action of latent proteins, but recent evidence suggests that lytic EBV replication has also a certain pathogenic role in lymphomagenesis, at least in the early phases of cell transformation. Particularly, in diffuse large B cell lymphoma (DLBCL), the EBV lytic cycle is by and large unexplored, so to disclose lytic cell contribution to lymphomagenesis, our aim was to evaluate viral early and late lytic gene expression in relation to several immune response markers in a series of EBV+ DLBCL from Argentina...

Diffuse large B-cell lymphoma (DLBCL), the most common type of malignant lymphoma, accounts for 30% of adult non-Hodgkin lymphomas. Epstein-Barr virus (EBV) -positive DLBCL of the elderly is a newly recognized subtype that accounts for 8-10% of DLBCLs in Asian countries, but is less common in Western populations. Five DLBCL-derived cell lines were employed to characterize patterns of EBV latent gene expression, as well as response to cytokines and chemotaxis. Interleukin-4 and interleukin-21 modified LMP1, EBNA1 and EBNA2 expression depending on cell phenotype and type of EBV latent programme (type I, II or III)...

We report a case of secondary diffuse large B-cell lymphoma (DLBCL) after azacitidine (AZA) treatment in a 63-years-old man with myelodysplastic syndrome. The patient suffered from febrile neutropenia after 10 cycles of AZA treatment. Despite the performance of a whole-body CT scan, which showed a multifocal low-density area in the liver and a multifocal nodular shadow in the lung, no malignant neoplasms could be detected. An autopsy was performed 6 months later, and a histopathological examination of the lesions of the liver and lung revealed the infiltration of large round-shaped tumor cells with necrotizing lesions...

Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) is a haematologic malignancy with poor prognosis when treated with chemotherapy. We evaluated response and survival benefits of chemoimmunotherapy in EBV-positive DLBCL patients. A total of 117 DLBCL patients were included in our retrospective analysis; 33 were EBV-positive (17 treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R-CHOP] and 16 with CHOP), and 84 were EBV-negative (all treated with R-CHOP)...

A case of a 16-year-old female with polyarticular juvenile idiopathic arthritis (JIA) since the age of 4 years is reported here. This patient also suffered from multiple congenital anomalies. On long-term treatment with oral methotrexate (MTX) and etanercept, multiple subcutaneous nodules were detected, which were accompanied by increased lactate dehydrogenase and uric acid levels. A biopsy of the largest nodule revealed Epstein-Barr (EB) virus-positive diffuse large B-cell lymphoma (DLBCL). The patient was classified as clinical stage IIIA due to a mediastinal lesion...

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma, whose main prognostic factor is closely related to germinal center B-cell-like subtype (GCB- DLBCL) or activated B-cell-like type (non-GCB-DLBCL). The most common type of primary central nervous system lymphoma is diffuse large B-cell type with poor prognosis and the reason is unclear. This study aims to stratify primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL) according to the cell-of-origin (COO) and to investigate the multiple proteins expression of C-MYC, BCL-6, BCL-2, TP53, further to elucidate the reason why primary central nervous system diffuse large B-cell lymphoma possesses a poor clinical outcome as well...

How Epstein-Barr virus (EBV) affects the clinical outcome of EBV-positive diffuse large B-cell lymphoma (DLBCL) remains largely unknown. The viral oncogene LMP1 is at the crux of tumorigenesis and cell survival. Therefore, we examined the association between LMP1high cells drug resistance. We first assessed SLAMF1 as a surrogate marker for LMP1high cells. LMP1 and its target gene CCL22 were highly expressed in SLAMF1high Farage cells. These cells survived longer following treatment with a combination of cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP)...

Epstein-Barr virus (EBV) infection is closely related to carcinogenesis of various cancers, and is also associated with the development of drug resistance in cancer stem cells. However, in EBV-positive cancer cells, the mechanistic details of the downstream signaling and the connection of PI3K with the NF-κB pathway for development of drug resistance remain controversial. Diffuse large B-cell lymphoma (DLBCL) and multiple myeloma (MM) cells infected by EBV display drug resistance-related proteins (MDR1, MRP1 and MRP2) and stem cell markers (OCT4 and SOX2)...

The aim of the study was to determine the clinical significance of EBV DNA in the peripheral blood mononuclear cells (PBMCs) from the patients with non-Hodgkin lymphoma (NHL). Newly diagnosed patients with NHL were enrolled in the study (n = 328), and clinical data retrospectively analyzed. EBV DNA was detectable in 34.8% of patients, and the positivity rate was 51.6% for T/NK cell subtype and 24.3% for B cell subtype (p < .001). In diffuse large B cell lymphoma (DLBCL), extranodal NK/T-cell lymphoma, nasal type (ENKTL), peripheral T-cell lymphoma not otherwise classified (PTCL...
