Lymphomas arising in the adrenal are rare, and to our knowledge, 2 cases of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphomas (DLBCL) in an adrenal pseudocyst have been reported. We report an incidental EBV-positive DLBCL arising in an adrenal pseudocyst in a 58-year-old man with a 7-year history of lymphoplasmacytic lymphoma (LPL). The DLBCL was present in the fibrinous exudate, while the LPL resided in the cyst wall. The patient underwent de-roofing of the same cyst 3 years previously; review of histology revealed foci of LPL in the cyst wall, but not of DLBCL...

The link between immunosuppressive therapy and increased lymphoma risk is well established in patients with solid organ transplantation. Epstein-Barr virus-positive (EBV) diffuse large B-cell lymphoma (DLBCL) is known to be a complication in patients receiving methotrexate for rheumatoid arthritis, and the risk of lymphoma in inflammatory bowel disease (IBD) has raised concerns regarding the lymphoproliferative potential of immunomodulatory therapy. In this report, we describe a case of EBV-positive DLBCL arising within the colon of a patient affected by ulcerative pancolitis...

AIMS: A new subtype of granzyme B (GrB) producing "regulatory B cells" (Bregs) has been recently described; these peculiar cytotoxic B-cells are significantly increased in interleukin-21 (IL-21)-rich settings, and in particular during HIV and EBV infection. Our aim is to report a unique case of an EBV-positive diffuse large B-cell lymphoma (DLBCL) with cytotoxic features arisen in an HIV+ patient, and to understand if this lesion may represent a proliferation of neoplastic cytotoxic Bregs...

Epstein-Barr virus (EBV)-positive mucocutaneous ulcer (EBVMCU) is a newly described entity occurring in elderly or iatrogenically immunocompromised patients. We describe a case of EBVMCU arising in a post-hematopoietic cell transplant patient, and followed by EBV-positive polymorphic post-transplant lymphoproliferative disorder (EBV(+) polymorphic PTLD). The patient, a 52-year-old woman, received chemotherapy and autologous peripheral blood stem cell transplantation (auto-PBSCT) for relapsed diffuse large B-cell lymphoma (DLBCL)...

Epstein-Barr virus (EBV)-associated B cell lymphoproliferative disorders may be seen in patients with angioimmunoblastic T cell lymphoma (AITL). Although both nodal and extranodal sites of involvement have been described, central nervous system involvement by B cell lymphoma following AITL has not previously been documented. We report a first example of such unusual presentation, in which an 80-year-old man developed diffuse large B cell lymphoma (DLBCL) in the cerebellum 4 months after the initial diagnosis of AITL...

Programmed cell death ligand 1 (PD-L1) is a cell surface glycoprotein that regulates the cellular immune response and serves as a targetable immune checkpoint molecule. PD-L1 is expressed on tumor cells and the immune microenvironment of several human malignancies, including a subset of aggressive lymphomas. We sought to investigate further the clinical and pathologic features of EBV-negative diffuse large B-cell lymphoma (DLBCL) cases that express PD-L1. Immunohistochemical staining using an anti-PD-L1 monoclonal antibody was performed on DLBCL cases from 86 patients...

BACKGROUND & OBJECTIVES: Primary central nervous system lymphomas (PCNSLs) are relatively uncommon, accounting for 2-3 per cent of primary brain tumours. Majority of these are diffuse large B cell lymphomas (DLBCL) occurring both in immunocompromised and immunocompetent patients. We undertook this study to classify PCNSL into germinal centre (GC) and non-germinal centre (NGC) type based on Hans classification and to find the role of Epstein-Barr virus (EBV) in pathogenesis both by conventional immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH)...

Expression of CD3 on a mature B cell neoplasm, such as diffuse large B cell lymphoma (DLBCL), is extremely rare. When it is present, it will cause diagnostic confusion since the classification of lymphoid neoplasms is largely based on immunophenotyping to determine the cell lineage. We report three cases of DLBCL with CD3 and other T cell-associated antigens. A literature search identifies 30 additional cases of DLBCL expressing CD3, with the majority (78.6 %) displaying cytoplasmic expression, while two of our cases demonstrate membranous staining...

Epstein-Barr virus (EBV), an oncogenic human virus, is associated with several lymphoproliferative disorders, including Burkitt lymphoma, Hodgkin disease, diffuse large B-cell lymphoma (DLBCL), and posttransplant lymphoproliferative disorder (PTLD). In vitro, EBV transforms primary B cells into lymphoblastoid cell lines (LCLs). Recently, several studies have shown that receptor tyrosine kinases (RTKs) play important roles in EBV-associated neoplasia. However, details of the involvement of RTKs in EBV-regulated B-cell neoplasia and malignancies remain largely unclear...

BACKGROUND: Epstein-Barr virus (EBV) positive diffuse large B-cell lymphoma (DLBCL) of the elderly is an entity introduced in the latest WHO classification of lymphoid tumors and defined in patients older than 50 years without prior lymphoma or immunodeficiency. However, recently it has also been seen in patients under 50. There is thus debate as to whether these are separate entities. MATERIALS AND METHODS: In this retrospective study, we analyzed de novo DLBCL admitted to our institute over a period of two years...

A small proportion of patients with chronic lymphocytic leukemia (CLL) may progress to large cell lymphoma, or Richter syndrome (RS). The large cells of RS may arise through transformation of the original CLL clone (clonally related) or represent a new neoplasm (clonally unrelated), which might be Epstein-Barr virus (EBV)-associated. We present a 61-year-old male with 5-year history of CLL who developed RS on bilateral adrenal glands. The tumor showed a vague nodular growth pattern separated by thick fibrous bands and the tumor cells were large and pleomorphic, with focal sheet-like growth pattern, in a background of small B and T-lymphocytes...

A 79-year-old woman was admitted with a 5-kg weight loss and anorexia. Computed tomography showed diffuse lymphadenopathy, and thickening of the duodenal and ileal walls. The patient then underwent biopsy of these sites. Pathological examination revealed duodenal Epstein-Barr virus (EBV)-positive peripheral T cell lymphoma-not otherwise specified (PTCL-NOS) and EBV-negative ileal diffuse large B-cell lymphoma (DLBCL) to be present simultaneously. Combination chemotherapy including rituximab produced a reduction of the duodenal EBV-positive PTCL-NOS lesion, but had no effect on the EBV-negative ileal DLBCL lesion...

Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) of the elderly is a provisional entity included in the 2008 WHO classification of lymphoid neoplasms. It is a disease typically seen in the elderly and thought to be associated with chronic EBV infection and severe immunosuppression with a component of immunosenescence. Recent research, however, has suggested that EBV-positive DLBCL can be seen in younger, immunocompetent patients. The diagnosis of EBV-positive DLBCL of the elderly is made through a careful pathological evaluation...

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease that great efforts had been made in to build up molecular and immunophenotypic subgroups that could relatively accurate indicate prognosis and give clue to therapy. Recently, CD30 was reported as a useful predictor with favorable clinical outcome. However, CD30 expression patterns and the clinicopathologic features of CD30 positive DLBCL are not well described thus far, especially in Asian patients. Here, we studied 232 cases of de novo DLBCL in East China to investigate the prevalence and clinicopathological features of CD30-positive DLBCL using a panel of immunohistochemical markers...

Epstein-Barr virus (EBV), a type of γ-herpes virus, is known to be a tumor virus. About 90% of adults were found to be persistently infected with EBV and this infection is responsible for Burkitt lymphoma (BL), extranodal NK/T cell lymphoma, Hodgkin lymphoma (HL), acquired Immune deficiency syndrome (AIDS)-associated lymphoma, and a portion of diffuse large B cell lymphomas (DLBCL). EBV-positive DLBCL in the elderly, a disease recognized in Japan, is described in the WHO classification as a new category of DLBCLs...

Epstein Barr Virus (EBV)-positive diffuse large B cell lymphoma (DLBCL) most frequently affects elderly patients, without previous immunosuppression, with frequent extra-nodal involvement and whose disease runs an aggressive clinical course with high International Prognostic Index (IPI) scores. Various EBV-related transforming mechanisms, much favored by immunosenescence, have been described, including activation of the NFKB transcriptional program. Elderly patients show poor survival after treatment with conventional CHOP regimens, even after addition of Rituximab...

The molecular pathogenesis of posttransplant diffuse large B cell lymphoma (PT-DLBCL) is largely unknown. We have recently shown that Epstein-Barr virus-positive (EBV(+)) and -negative (EBV(-)) PT-DLBCL have distinct gene expression profiles, and the transcriptomic profile of EBV(-) PT-DLBCL is similar to that of DLBCL in immunocompetent individuals (IC-DLBCL). To validate these observations at the genomic level, we performed array-comparative genome hybridization (aCGH) analysis of 21 EBV(+) PT-DLBCL, 6 EBV(-) PT-DLBCL, and 11 control IC-DLBCL, and subsequently combined genomic and transcriptomic data...

A 75-year-old woman consulted her doctor in January 2014 because of pain in the dorsum of the hands, elbows, shoulders, and knees, bilaterally, and was diagnosed as having remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome. Although the joint pain improved with low-dose prednisolone administration, she was referred to our department in April of 2014 because she had become aware of swelling of the right cervical lymph node. Biopsy of the lymph node demonstrated that she had Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) of the elderly, and colonoscopy revealed early colon cancer...
