    Abstract:

    Virus-associated hemophagocytic syndromes are a heterogeneous group of disorders in which viral infection is associated with a proliferation of hemophagocytic histiocytes throughout the reticuloendothelial system. The authors report the case of a 24-year-old Vietnamese male who developed a hemophagocytic syndrome associated with Epstein-Barr virus (EBV) and who died following a rapidly progressive course. A proliferation of reactive-appearing lymphoid cells was associated with an extensive proliferation of erythrophagocytic histiocytes. Immunophenotypically, the lymphoid infiltrate consisted of CD56+ natural killer cells, predominantly CD8+ T-cells and rare B-cells (CD20+). Double-label immunohistochemical studies showed CD3+ T-cells and CD56+ natural killer cells to be distinct cell populations. Combined immunohistochemical-in situ hybridization studies localized EBV to CD43+, CD3-, CD68-, lymphoid-appearing cells, indicating the presence of EBV within natural killer cells. Southern hybridization analysis of EBV genomic termini revealed clonal EBV genome. However, there was no detectable immunoglobulin or T-cell receptor gene rearrangements. The findings indicate that this case of hemophagocytic syndrome represents a clonal proliferation of natural killer cells containing EBV and highlights the importance of the analysis of EBV genomic termini for determination of clonality in EBV-associated proliferations. It is possible that other cases of fulminant EBV-associated hemophagocytic syndromes represent clonal natural killer cell proliferations.
