Thirty-five cases of Hodgkin's disease (HD) were analysed for the presence of Epstein-Barr virus (EBV) and human herpesvirus-6 (HHV-6) DNA. EBV genomes were detected in 11/35 cases while none of the cases was positive for HHV-6. Ten of the EBV-positive cases were subsequently analysed using a probe for the terminal region of the virus; the results suggested that the EBV-infected cells were clonally expanded. EBV subtypes specific DNA amplification was used to demonstrate that EBV subtype A, and not subtype B was present in the EBV-positive cases. The age distribution of the EBV-positive cases indicated a statistically significant trend for an increase in positivity with increasing age. This is the first indication that EBV is significantly associated with any subset of HD patients.

This study aimed to investigate the role of human herpesvirus (HHV) infection in refractory intestinal graft-versus-host disease (GI-GVHD) after hematopoietic stem cell transplantation (HSCT) and its diagnosis and treatment. This study retrospectively analyzed patients presenting with refractory GI-GVHD after allogeneic HSCT (allo-HSCT) with concomitant colonoscopy and mucosal biopsy at Lu Daopei Hospital, Yanda, Hebei, from March 2022 to July 2024. Human herpesvirus 6 (HHV6), HHV7, cytomegalovirus (CMV), and Epstein-Barr virus (EBV) detection with the RQ-PCR method.

Primary thyroid lymphomas comprise largely extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (EMZL) and diffuse large B-cell lymphoma (DLBCL), followed by follicular lymphoma (FL). They commonly develop from a background of Hashimoto's thyroiditis (HT), where dysregulated immune responses trigger autoreactive infiltrates and drive clonal B-cell evolution. To understand how these lymphomas and their relapse evolve, we investigated 10 cases by mutation profiling, including five with metachronous lymphomas [primary lymphoma (EMZL = 4, DLBCL = 1) with local relapse (EMZL = 3, DLBCL = 2)], one composite EMZL and Epstein-Barr virus (EBV)-positive DLBCL, and four lymphomas (EMZL = 3, FL = 1) with prior or subsequent biopsy showing HT.

Epstein-Barr Virus (EBV)-positive neuroendocrine carcinoma (NEC) is a rare neoplasm with limited histopathological and therapeutic data. This report presents 22 cases of EBV-positive NEC, analyzing age distribution, morphology, and immunophenotype. The median patient age was 47 years (range: 27-67 years), with a male-to-female ratio of 17:5.

Background: The Cancer Genome Atlas (TCGA) has identified four distinct molecular subtypes of gastric cancer (GC) with prognostic significance: Epstein-Barr virus (EBV)-positive, microsatellite instability (MSI)-high, genomically stable (GS), and chromosomal instability (CIN). Unfortunately, the complex analysis required for TCGA classification limits its practical use in clinical settings. Our study sought to devise a next-generation sequencing (NGS)-based method to classify GC more efficiently, serving as a promising biomarker for prognosis and immunotherapy efficacy.
