Age-related EBV-associated lymphoproliferative disorders form a new clinicopathological group. Until recently, this group was associated with diffuse large B-cell lymphoma (DLBCL), characterised by an aggressive clinical presentation and a poor prognosis. Recent findings in Western Caucasian patients, however, suggest that this entity covers a wide spectrum of diseases, ranging from reactive follicular hyperplasia (HR) to DLBCL. We report the case of an 85-year-old Caucasian man showing lymphadenopathy and numerous hypodense lesions of the liver...

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...

Lymphoepithelial carcinoma commonly occurs at the nasopharynx and rarely occurs at other sites in the head and neck region. It is well known to occur at limited patients of local area as Asia or Arctic Circle. Related to this point, it is pointed out that this tumor has strong relation with Epstein-Barr Virus (EBV) infection. In this time, we experienced to treat lymphoepithelial carcinoma with metastatic cervical lymph nodes occurring at parotid gland. The morbidity ratio of this tumor is less than one percent of all parotid gland tumors...

We managed a patient with an Epstein-Barr virus-associated T-cell lymphoblastic lymphoma. Mediastinal tumor cells at initial admission were positive for CD4, CD8, and TdT. Interestingly, a lymph node at necropsy was compatible for a CD4-positive peripheral T-cell lymphoma without CD8 and TdT expression, suggesting a different phenotype from the mediastinal tumor. Tumor cells in pleural effusion continued to proliferate in in vitro and were designated as WILL4. WILL4 cells were positive for CD3, CD4, CD8, CD21, T-cell receptor (TcR) αβ, and TdT, indicating a similar phenotype to thymocytes...

Squamous cell carcinoma of unknown primary of the head and neck (SCCUP) is a heterogeneous disease entity that requires careful examination to locate the occult primary. We examined the diagnostic value of expression of biomarkers, such as human papillomavirus (HPV), p16 and Epstein-Barr virus (EBV), in metastatic lymph nodes vs. (18) F-fluorodeoxyglucose ((18) F-FDG) positron emission tomography/computed tomography (PET/CT). We prospectively enrolled 54 consecutive SCCUP patients who received HPV, p16 and EBV analyses of lymph node fine-needle aspirates and (18) F-FDG PET/CT scans and subsequently underwent examinations and biopsies under general anesthesia to detect primary tumors...

BACKGROUND: In vitro and clinical studies suggest that the oncogene LMP1 (latent membrane protein 1) encoded by Epstein-Barr virus (EBV) plays a role in the development of nasopharyngeal carcinoma (NPC) and the formation of metastases in immunocompetent individuals. However, whether LMP1 itself is sufficient to drive these events in immunocompetent hosts remains elusive due to the lack of appropriate experimental models. The aim of this study was to study LMP1-dependent tumorigenesis and metastasis in BALB/c mice inoculated with BALB/c-3T3 cells expressing N-LMP1 (a Taiwanese NPC variant)...

AIMS: A new subtype of granzyme B (GrB)-producing regulatory B cells (Bregs ) has been described recently; these peculiar cytotoxic B cells are increased significantly in interleukin (IL)-21-rich settings, and in particular during HIV and Epstein-Barr virus (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 ...

A 16-year-old boy of Caucasian ethnicity was evaluated for recurrent febrile episodes occurring during most of his life without establishment of any microbial aetiology. During febrile episodes he developed extensive splenomegaly, lymphadenopathy, anaemia, severe abdominal pain and general malaise. Lymph node biopsies demonstrated inflammation and sinus histiocytosis but no malignancy or granuloma. The patient underwent seroconversion for Epstein-Barr virus (EBV) infection during the hospitalisation. Genetic testing identified a hemizygous frameshift mutation in the X linked inhibitor of apoptosis (XIAP)-gene as well as variants in the MEFV gene indicating Familial Mediterranean Fever (FMF)...

INTRODUCTION: Nasopharyngeal carcinoma (NPC) is a common cancer in the North-East region of India. Though the role of environmental contributors of NPC in the North-Eastern part of India is firmly established, EBV as an etiological agent in the region remains unexplored. MATERIAL AND METHODS: Fifty-one patients, who presented at the department of ENT, NEIGRIHMS and were confirmed as NPC upon histopathological examination, were included in the study. Chromogenic in-situ hybridization (CISH) was used for the evaluation of EBER (Epstein Barr Virus Encoded RNA)...

BACKGROUND: Most malignant lymphomas in HIV-patients are caused by reactivation of EBV-infection. Some lymphomas have a very rapid fulminant course. HHV-8 has also been reported to be a cause of lymphoma. The role of CMV in the development of lymphoma is not clear, though both CMV and HHV-8 have been reported in tissues adjacent to the tumour in Burkitt lymphoma patients. Here we present a patient with asymptomatic HIV infection, that contracted a primary cytomegalovirus (CMV) infection and human herpes virus 8 (HHV-8) infection...

The presence of CD30-expressing Hodgkin-like cells with a background of inflammation and eosinophils in a young adolescent is usually diagnostic of classical Hodgkin lymphoma. Herein we present the case of a 12-year-old boy presenting with enlarged cervical lymph node characterized by the presence of Hodgkin-like cells expressing CD30 and EBV-LMP1 with a Hodgkin-like background. The Hodgkin-like cells were negative for CD15, CD20, CD45, and Pax-5. The tumor cells, however, expressed several cytokeratins, confirming the diagnosis of an undifferentiated carcinoma nasopharyngeal type...

Both gastric adenocarcinoma of fundic gland type (ADC-FG) and carcinoma with lymphoid stroma (lymphoepithelioma-like carcinoma, LELC) are relatively rare. Epstein-Barr virus (EBV) has been implicated in the pathogenesis of LELC. However, the pathogenesis of ADC-FG, as well as the role of EBV in the carcinogenesis of LELC, remain unclear and under debate. The current study presents a case of concurrent ADC-FG and LELC in the stomach in a 69-year-old man. Total gastrectomy was performed, and two separate masses were identified...

Follicular dendritic cell (FDC) sarcoma is a rare neoplasm that occurs predominantly in lymph nodes. One third of FDC sarcomas happens in extranodal sites. There are 2 morphologic variants of this tumor: conventional and inflammatory pseudotumor (IPT)-like. IPT-like FDC sarcomas are reported mostly in females and usually involve the spleen and liver. In all cases of IPT-like FDC sarcoma the Epstein-Barr virus (EBV) was positive by in situ hybridization except one instance. We report a case of 53-year-old woman who presented with abdominal discomfort...
