The review is dedicated to features of clinical manifestations of infections caused by Epstein- Barr virus (EBV) in HIV-infected patients, problems of diagnostics and execution of antiviral therapy in the case of combination of these infections. Individuals at AIDS stage develop tumors, associated with EBV: non-Hodgkin's lymphomas, including Berkitt's,lymphoma, primary B-cell lymphoma,of CNS, nasopharyngeal carcinoma. Formation of lymphoid interstitial pneumonitis and leukoplakia is known to be associated with EBV. A large list of preparations that are inhibitors of EBV replication are currently known, however, there is no clear pathogenetically justified therapy scheme for patients with this infection against the background of HIV-infection.

Gastric carcinoma with lymphoid stroma (GCLS) is characterized by dense intra-and peritumoral lymphocytic infiltration and a high rate of Epstein Barr Virus (EBV) infection, suggesting being a promising candidate for immunotherapy. We investigated correlations between PD-L1 expression and clinicopathologic factors, including EBV positivity and microsatellite instability (MSI) status in GCLSs. The study included resected 214 GCLSs and 300 gastric adenocarcinomas (GACs) for control.

Epstein-Barr virus (EBV) is one of the most common causes of infection from the herpes virus family which also possesses oncogenic potential. EBV-associated smooth muscle tumors (EBV-SMT) are often found in the CNS but here we present the case of a 50-year-old woman with EBV-SMT in the liver. This patient had a kidney transplant in 2009 and had been undergoing immunosuppressive therapy to support her transplant.

Secondary hemophagocytic lymphohistiocytosis (HLH) syndrome, a fatal disorder characterized by NK/T-cell deficiency, cytokine storm, and organ damage, is rare in chronic lymphocytic leukemia (CLL). Ibrutinib, the first generation of irreversible Bruton's tyrosine kinase inhibitor, has been the first-line therapy for CLL. As an off-target effect, it can also block IL-2 inducible T-cell kinase (ITK), which is essential in maintaining normal NK and T-cell functions.

Although different types of prognostic indices have been applied in extranodal NK-/T-cell lymphoma (ENKTL), they are based mainly on clinical characteristics before treatment. Moreover, these methods lack early assessment and tumor metabolic parameters. It remains unclear whether changes in the plasma Epstein-Barr virus DNA (EBVDNA) status and SUVmax after two cycles of chemotherapy may predict disease prognosis.

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.
