Angioimmunoblastic T-Cell Lymphoma Presenting with an Acute Serologic Epstein-Barr Virus Profile.
Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive peripheral T-cell lymphoma typically characterized by prominent lymphadenopathy and B-symptoms at the time of presentation, polyclonal hypergammaglobulinemia, autoimmune hemolysis and frequent but highly variable involvement of Epstein-Barr virus (EBV). Lymph node biopsy findings typically include effacement of nodal architecture, polymorphic infiltrate, atypical T-cells (usually CD4+/CD10+/PD1+) and prominent proliferations of high endothelial venules and follicular dendritic cells. However, this classic constellation of pathologic findings is often initially obscured by a prominence of EBV+ B-immunoblasts with or without associated peripherally circulating EBV DNA. Here we document the first reported case of an acute serologic EBV profile (VCA-IgM) in a patient with AITL, and we recommend that clinicians maintain a high index of suspicion for AITL in the appropriate clinical scenario, irrespective of Epstein-Barr related findings.
