Case Report: Epstein-Barr virus-positive follicular lymphoma with high PD-L1 expression

We present a case of EBV-positive follicular lymphoma with high PD-L1 expression and analyze its clinicopathological features. The patient was treated with R-CHOP chemotherapy combined with the anti-CD20 antibody (rituximab), achieving favorable therapeutic outcomes. This case provides valuable insights for the pathological diagnosis and treatment of EBV-positive follicular lymphoma, as well as the role of EBV infection in PD-L1 expression. Furthermore, it raises the question of whether high PD-L1 expression suggests that immunotherapy could serve as another potential treatment strategy for EBV-positive follicular lymphoma.
