BACKGROUND: Epstein-Barr virus positive peripheral T cell lymphoma (EBV + PTCL) is a rare type of lymphoproliferative disorder which is always present in late adulthood. However, pediatric EBV + PTCL is extremely rare and always present with lymphadenopathy. Additionally, gene detection was not performed in all of these pediatric patients. CASE PRESENTATION: We report an EBV + PTCL in a 9-year-old child with initial symptom of subcutaneous masses without lymph node involvement...

The present case report presents a rare case of Epstein-Barr virus (EBV)-associated early gastric carcinoma with lymphoid stroma, accompanied by lymph node metastasis. A 61-year-old woman was referred to our hospital following observation of a gastric mass lesion that was initially diagnosed at a medical check-up. Esophagogastroduodenoscopy revealed a slightly elevated lesion with a central irregular depression in the middle third of the stomach. Endoscopic ultrasonography revealed a well-circumscribed hypoechoic mass located predominantly within the submucosa and the mucosa...

The concentration and distribution of rare earth elements (REE) in nasopharyngeal carcinoma (NPC) were measured to investigate connections with tumor size, lymph node metastasis, clinical stages, and Epstein-Barr virus (EBV) infection. There were 30 patients with NPC who met the criteria for inclusion in the present study. The EBV copy number, as well as the concentration and distribution of REE, was analyzed. EBV was detected using reverse transcription-polymerase chain reaction, with the concentrations of REE in NPC tissues measured using inductively coupled plasma-tandem mass spectrometry...

In this case of suspected sphenoid wing meningioma, Ga-DOTATATE PET/CT showed a somatostatin receptor (SSR)-expressing tumor with extension to the nasopharynx and SSR-expressing cervical lymph nodes. Subsequent biopsy from the nasopharynx revealed an Epstein-Barr virus (EBV)-associated, undifferentiated World Health Organization type 3 nasopharyngeal carcinoma (NPC), a potential clinical pitfall due to the reported high SSR expression of this tumor subtype. In consideration of the high target-to-background contrast, SSR ligands might be superior to F-FDG for EBV-associated NPC PET imaging, particularly at the skull base...

Autoantibodies to breast and other cancers are commonly present in cancer patients. A method to rapidly produce these anti-cancer autoantibodies in the lab would be valuable for understanding immune events and to generate candidate reagents for therapy and diagnostics. The purpose of this report is to evaluate sentinel nodes (SNs) of breast cancer patients as a source of anti-cancer antibodies. Radiotracer lymphatic mapping in 29 patients with breast cancer confirmed the identity of the SNs which provided source cells for this study...

INTRODUCTION: The distribution of extranodal NK/T-cell lymphoma (ENKTCL) is highly inhomogeneous throughout the world. In Sub-Saharan Africa, despite the precocity of Epstein-Barr virus (EBV) infection and its endemicity, ENKTCL remains exceptionally reported. The purpose of this study was to report the epidemiological, clinical, paraclinical, and evolutionary characteristics of ENKTCL at the Aristide LeDantec University Hospital in Dakar, Senegal. METHODOLOGY: A 5-year retrospective review of all patients with histopathological, immunohistochemical, and in situ hybridization proven cutaneous lymphomas RESULTS: We collected seven cases corresponding to a frequency of 1...

We report a case of classical Hodgkin lymphoma type post-transplant lymphoproliferative disorder (HL-PTLD) after kidney transplantation to highlight the difficulty of distinguishing this disorder from Hodgkin lymphoma-like PTLD (HL-like PTLD). Through this case report and literature review, we seek to clarify definitive pathologic features to differentiate these two conditions. A 38-year-old male kidney transplant recipient who had been receiving immunosuppressants was admitted to our hospital with unidentified high fever...

BACKGROUND: According to the 7th edition of the American Joint Committee on Cancer (AJCC) staging system, over 50% of patients with nasopharyngeal carcinoma (NPC) have N1 disease at initial diagnosis. However, patients with N1 NPC are relatively under-researched, and the metastasis risk of this group is not well-stratified. This study aimed to evaluate the prognostic values of gross tumor volume of metastatic regional lymph node (GTVnd) and pretreatment serum copy number of Epstein-Barr virus (EBV) DNA in predicting distant metastasis of patients with N1 NPC, and to develop an integrated prognostic model that incorporates GTVnd and EBV DNA copy number for this group of patients...

A 70-year-old woman with lymphadenopathy was admitted to hospital in 2008. Lymph node biopsy showed reactive lymphoid hyperplasia (RH) with monoclonal proliferation of EBV. Her lymphadenopathy regressed without treatment. In 2014, the patient presented with nasal obstruction because of a left nasal mass. She was diagnosed with EBV-positive diffuse large B-cell lymphoma (DLBCL) of the elderly based on the examination of a biopsy specimen of the mass. The IgH rearrangement in the specimens from the 2008 and the 2014 revealed that they were genetically identical...

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...

We describe a rare case of chronic active Epstein-Barr virus (CAEBV) infection, with infiltration of the skeletal muscle. A 19-year-old woman with swollen cervical lymph nodes and a fever was referred to our hospital. Swelling of the trapezium muscle and elevation of creatinine kinase level were observed. Biopsy results of the brachialis muscle revealed infiltration of Epstein-Barr virus (EBV)-encoded RNA-positive CD8 T lymphocytes. The EBV virus load in the peripheral blood was high, and EBV monoclonality was determined by Southern blot analysis...

We report a case of EBV+ and HHV-8+ multicentric Castleman disease with plasmablastic aggregates in an HIV-positive individual. A 41-year-old man presented in early 2015 with fevers, sweats, weight loss, intractable itching, and on subsequent testing was found to be HIV positive. Investigations showed cervical lymphadenopathy and splenomegaly. He was treated for HIV and his symptoms resolved. His symptoms recurred in January 2016, and a provisional diagnosis of multicentric Castleman disease was entertained...

Langerhans cell histiocytosis (LCH) is an inflammatory myeloid neoplastic proliferation with variable clinical behavior caused by the accumulation of CD1a(+)/CD207(+) histiocytes, associated with a variable number of eosinophils, lymphocytes, plasma cells and multinucleated giant cells, most commonly observed in male children. LCH is uncommon in the head and neck region, occurring as ulcerated and reddened plaques or nodules that cause destruction of adjacent soft tissues and bone. The exact etiology of LCH is still unknown and controversial, with possible etiologic role of viruses, including Epstein-Barr virus (EBV)...

Isolated MYC rearrangement without other recurrent genetic abnormalities is rare in B lymphoblastic leukemia/lymphoma (B-ALL/LBL), with most cases reported in pediatric patients. We report 3 adult cases with lymphoblasts showing a precursor B cell immunophenotype, and isolated MYC/IGH translocation. All 3 cases occurred in male patients with initial presentation of diffuse lymphadenopathy. Cases 1 and 2 had B-ALL with significantly increased lymphoblasts in peripheral blood and bone marrow. Case 3, a patient with human immunodeficiency virus infection, had the diagnosis of B-LBL made on a retroperitoneal lymph node biopsy and had no peripheral blood or bone marrow involvement...

BACKGROUND: Epstein-Barr virus (EBV) is closely associated with many human diseases, including a variety of deadly human malignant tumours. However, due to the lack of ideal animal models,the biological characteristics of EBV, particularly its function in tumourigenesis, have not been determined. Chinese tree shrews (Tupaia belangeri chinensis), which are similar to primates, have been used to establish a variety of animal models and have recently received much attention. Here, we established tree shrews as a model for EBV infection by intravenous injection...

Skin biopsies of 41 angioimmunoblastic T-cell lymphoma patients were retrospectively analyzed for the expression of follicular helper T-cell (TFH) markers, Epstein-Barr virus (EBV), and the presence of RHOA (p.G17V) and IDH2 (p.R172K/S) mutations using allele-specific polymerase chain reaction. We categorized cases into 4 distinctive patterns: (1) low-density lymphocytic perivascular infiltrates (n=11), (2) dense perivascular infiltrates with atypical cells and occasional inflammatory cells (n=13), (3) diffuse infiltrates reminiscent of angioimmunoblastic T-cell lymphoma (n=4), or (4) other aspects (n=13)...
