Recognizing Lymphoma Risk in EBV- and HIV-Positive Patients: The Otorhinolaryngologist’s Perspective

Epstein–Barr virus (EBV) is a key oncogenic pathogen implicated in the development of lymphomas, particularly among HIV-positive and immunocompromised individuals. While the association between EBV and lymphoma is well established, the mechanisms underlying progression from infection to malignancy—especially in the head and neck region—remain incompletely understood. This review offers a comprehensive analysis of the pathophysiological pathways by which EBV and HIV contribute to lymphomagenesis, with an emphasis on latency patterns, immune evasion, and epigenetic “hit and run” oncogenesis. Notably, it integrates novel findings on the diagnostic implications of EBV latency proteins, explores HIV-mediated B-cell dysregulation, and evaluates the emerging landscape of targeted therapies, including monoclonal antibodies and lytic cycle inducers. By focusing specifically on head and neck lymphomas, this review underscores a clinically underrepresented domain and offers insights that may guide future diagnostics, surveillance, and treatment strategies in vulnerable patient populations. This review also highlights the pressing need for improved animal models and continued research into EBV-specific therapeutic targets.
