Epstein-Barr virus (EBV) is a common pathogen that infects individuals early in life, primarily in B lymphocytes. Conditions of immunodeficiency and immunosuppressive therapies have brought attention to EBV-related lymphoproliferative disorders, which can range from indolent to aggressive lymphomas. These disorders can be diagnostically challenging due to overlapping morphology and immunophenotype.
Simple Summary Epstein-Barr virus (EBV)-associated lymphoproliferative disorders have been garnering attention in recent years. EBV infects people primarily in their first years of life. The viral genome is maintained in a latent phase within the host cells, usually B-lymphocytes. The immunosuppression of different origins alters homeostasis between the virus and the host, enabling EBV-linked lymphoproliferative disorders to appear. Entities with different biological behaviors often share some morphological and phenotypic features, making the diagnosis complicated. Nodal and extra-nodal sites, including the gastrointestinal tract may be involved. This review, divided into three parts, aims to summarize the available clinical, pathological, molecular and therapeutic data on EBV-associated lymphoproliferative disorders involving the gastrointestinal tract. In this part of the review, we discuss plasmablastic lymphoma, extra-cavitary primary effusion lymphoma and Burkitt lymphoma. Epstein-Barr virus (EBV) is a common pathogen infecting people primarily early in life. The virus has the ability to persist throughout a person's life, usually in B lymphocytes. Conditions of immunodeficiency as well as the introduction of immunosuppressive therapies and the advent of transplant technologies has brought immunodeficiency-associated lymphoproliferative disorders into view, which are often driven by EBV. The group of EBV-associated lymphoproliferative disorders includes different entities, with distinct biological features, ranging from indolent disorders, which may even spontaneously regress, to aggressive lymphomas requiring prompt and adequate treatment. These disorders are often diagnostically challenging due to their overlapping morphology and immunophenotype. Both nodal and extra-nodal sites, including the gastrointestinal tract, may be involved. This review, divided in three parts, summarizes the clinical, pathological, molecular features and treatment strategies of EBV-related lymphoproliferative disorders occurring in the gastrointestinal tract and critically analyzes the major issues in the differential diagnosis. In this part of the review, we discuss plasmablastic lymphoma, extra-cavitary primary effusion lymphoma and Burkitt lymphoma.
