A virus-associated hemophagocytic syndrome (VAHS) is a non-neoplastic, generalized histiocytic proliferation with prominent hemophagocytosis associated with a systemic viral infection. Epstein-Barr virus (EBV) is one candidate for this association but serologic and molecular biologic studies have been lacking in many cases. Although VAHS is generally a benign process, EBV-associated hemophagocytic syndrome (EBV-AHS) is often fatal and has a relatively high mortality rate. Therefore, EBV-AHS must be distinguished from VAHS caused by other viruses. Recent evidence indicates that the pathophysiology in EBV-AHS appears to be mediated by the unrestricted release of cytokines produced by the EBV-infected T cells. Clinical and laboratory findings, the differential diagnosis, virology studies, pathophysiology, and treatment in EBV-AHS are reviewed.

Virus-associated hemophagocytic syndrome (VAHS) is a non-neoplastic, generalized histiocytic proliferation with prominent hemophagocytosis associated with a systemic viral infection. Although Epstein-Barr virus (EBV) is one candidate virus for this association, thorough serologic and molecular biologic studies to determine the presence of the viral infection have been lacking in many reports. Whereas elevated liver function tests are common findings in patients with VAHS, exudative ascites and abdominal lymphadenopathy are rare. We describe a case of EBV-AHS masquerading as lymphoma in which treatment with intravenous immunoglobulins was associated with complete clinical remission at 2 years and 6 months after the onset. Regardless of the exact mechanism responsible for ascites formation in VAHS, this case adds support to the possible involvement of EBV in patients with abdominal lymphadenopathy and ascites.
