Lymphoepithelioma-like carcinoma (LELC) is a rare neoplasm of the cervix. The importance of distinguishing this undifferentiated carcinoma with a predominant lymphocytic infiltrate lies in the fact that despite being poorly differentiated they have a better prognosis. The diagnosis however becomes more challenging when the pathologist is provided with a small cervical biopsy or a Papanicolaou smear. While the reports describing histology and their relation to Epstein-Barr virus (EBV) are many, there are only few case reports describing the cytology of these tumors...

Chronic active Epstein-Barr virus infection (CAEBV) is a prototype of the EBV-associated T- or NK-cell lymphoproliferative diseases, which also include hypersensitivity to mosquito bites and severe-type hydroavacciniforme. The manifestations of CAEBV are often self-limiting with minimum supportive care or only prednisolone and cyclosporine A with or without etoposide. However, allogeneic hematopoietic stem cell transplantation (HSCT) is the only cure, without which patients with CAEBV die within several years...

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by immune activation and subsequent widespread organ damage. Patients affected by HLH commonly develop fever, cytopenias, liver damage, neurologic manifestations, and hypercytokinemia. In this case, we describe a 60-year-old male who presented with HLH and concurrent Epstein-Barr virus, cytomegalovirus, and Candida infections and was subsequently diagnosed with a Hodgkin lymphoma. This case highlights the importance of considering a cancer diagnosis in the differential diagnosis of patients presenting with HLH...

Strategies to prevent active infection with certain double-stranded DNA (dsDNA) viruses after allogeneic hematopoietic cell transplantation (HCT) are limited by incomplete understanding of their epidemiology and clinical impact. We retrospectively tested weekly plasma samples from allogeneic HCT recipients at our center from 2007-2014. We used quantitative PCR to test for cytomegalovirus (CMV), BK polyomavirus (BKV), human herpesvirus 6B (HHV-6B), HHV-6A, adenovirus (AdV), and Epstein-Barr virus (EBV) between days 0-100 post-HCT...

BACKGROUND: Gastric carcinoma with lymphoid stroma (GCLS) is characterized by undifferentiated carcinoma mixed with prominent lymphoid infiltration. GCLS has unique clinicopathological features and a better prognosis compared to other types of gastric cancer. We analyzed the clinicopathological features of early GCLS in relation to lymph node metastasis (LNM). METHODS: We performed a retrospective analysis of 241 patients diagnosed with GCLS confined to the mucosa or the submucosa between March 1998 and December 2015...

BACKGROUND: Epstein-Barr Virus (EBV) is a widely disseminated lymphotropic herpes virus implicated in benign and malignant disorders. In transplant patients, immunosuppressive drugs (cyclosporine) diminish control of EBV replication, potentially leading to lymphoproliferative disorders (LPD). Rheumatoid arthritis (RA) patients have impaired control of EBV infection and have EBV load ten times higher than controls. As post transplant patients, patients with RA have increased risk of developing lymphomas...

The successful use of immune cell checkpoint inhibitors PD-1 and PD-L1, over the past 5 y has raised the concern of using immunotherapy to treat various cancers. Epstein-Barr virus-associated gastric cancer (EBVaGC) exhibits high infiltration of lymphocytes and high amplification of immune-related genes including PD-L1 as distinguished from Epstein-Barr virus-non-associated gastric cancer (EBVnGC). Here, we presume that this PD-1/PD-L1 pathway may hinder the efficacy of adoptive T cell therapy toward EBVaGC...

Mounting evidence indicates that infection with Epstein-Barr virus (EBV) has a major role in the pathogenesis of multiple sclerosis (MS). Defective elimination of EBV-infected B cells by CD8(+) T cells might cause MS by allowing EBV-infected autoreactive B cells to accumulate in the brain. Here we undertake a comprehensive analysis of the T-cell response to EBV in MS, using flow cytometry and intracellular IFN-γ staining to measure T-cell responses to EBV-infected autologous lymphoblastoid cell lines and pools of human leukocyte antigen (HLA)-class-I-restricted peptides from EBV lytic or latent proteins and cytomegalovirus (CMV), in 95 patients and 56 EBV-seropositive healthy subjects...

Epstein-Barr virus (EBV) is a human gammaherpesvirus associated with several malignancies. We reported previously that an EBV lytic gene product BRRF2 is involved in the maturation of progeny virus. To analyze the domain(s) needed for efficient production of progeny, we prepared a series of deletion mutants and found two functional domains in the N- and C-terminal regions by complementation assays. Immunofluorescence analyses revealed that BRRF2 lacking the C-terminal region demonstrated aberrant localization in both the nucleus and cytoplasm, whereas wild-type BRRF2 was localized predominantly in the cytoplasm...

BACKGROUND Myocarditis, defined as inflammation of myocardial tissue of the heart, is an uncommon cardiac presentation and is due to a variety of causes. It affects 1% of the US population, 50% of which is caused by coxsackie B virus. Cardiac tissue is the prime target, and destruction of myocardium results in cardiac failure with fluid overload. CASE REPORT Our patient was a 57-year-old woman with fever, headache, neck pain, and generalized malaise. Her white blood cell count was 13×10³ cells/mm³. Interestingly, lumbar puncture ruled out meningitis...

OBJECTIVES: Epstein-Barr virus (EBV) is involved in the pathogenesis of approximately 40% of lymphoproliferative disorders (LPDs) arising in patients receiving immunosuppressive treatment (IST) for rheumatic diseases, but data from large cohorts are still not available. We aimed to identify clinicopathological features, management and outcome of this condition. METHODS: We reviewed all published cases of EBV-encoded RNA (EBER)-positive LPDs and included in our analysis one unpublished patient diagnosed in our Hospital...

Incidental cases of localized fibrin-associated Epstein-Barr virus (EBV)+ large B-cell proliferations have been described at unusual anatomic sites and have been included in the category of diffuse large B-cell lymphoma associated with chronic inflammation (DLBCL-CI) in the WHO Classification. We describe 12 cases and review the literature to define their clinicopathologic spectrum and compare features with typical cases of DLBCL-CI. Median age was 55.5 years with a M:F ratio of 3. In all 12 cases, the lymphoma was an incidental microscopic finding involving atrial myxomas (n=3), thrombi associated with endovascular grafts (n=3), chronic hematomas (n=2), and pseudocysts (n=4)...

Metastases to breast are much rarer than primary breast tumors. We now present a case of 45-year-old female, who presented with an isolated breast mass. A positron emission tomography-computed tomography (PET-CT) done revealed hypermetabolic right breast nodules, soft tissue deposits, and multiple nodal involvement. The biopsy from the breast and axillary lymph node showed dense lymphoid infiltrate and was interpreted initially as granulomatous inflammation. However, the lumps were hard and suspicious for primary breast cancer, so an immunohistochemistry for cytokeratin was performed which highlighted the epithelial cell clusters masked within the inflammatory infiltrate and the diagnosis of undifferentiated carcinoma, lymphoepithelioma-like was made...

Viral detection presents a host of challenges for even the most sensitive analytical techniques, and the complexity of common detection platforms typically preclude portability. With these considerations in mind, we designed a paper microzone plate-based virus detection system for the detection of viral genetic material that can be performed with simple instruments. The sensing system can detect viral cDNA reverse-transcribed from total RNA extraction by utilizing a biotinylated capture probe and an Alexa Fluor® 647-labeled reporter probe...

Primary Epstein-Barr virus (EBV) infection is almost always a self-limited disease characterized by sore throat, fever, and lymphadenopathy. Hepatic involvement is usually characterized by mild elevations of aminotransferases and resolves spontaneously. Although isolated gallbladder wall thickness has been reported in these patients, acute acalculous cholecystitis is an atypical presentation of primary EBV infection. We presented a young women admitted with a 10-day history of fever, nausea, malaise who had jaundice and right upper quadrant tenderness on the physical examination...

Extranodal NK/T-cell lymphoma (ENKTL), nasal type, is a rare type of non-Hodgkin lymphoma that is commonly seen in East Asian countries and is associated with Epstein-Barr virus infection. This is a retrospective study where we describe nine cases of ENKTL; nasal type diagnosed and treated at our center over a period of 2 years. These cases were analyzed retrospectively for clinical presentation (age, sex, site of involvement), immunophenotype, treatment, response and toxicity profile. Sino-nasal symptoms (blocked nose, headache, epistaxis, regurgitation) were the most common presenting complaints (n = 8)...
