Cytomegalovirus infection-associated hemophagocytic syndrome.

Infection-associated hemophagocytic syndrome is a life-threatening condition characterized by prolonged fever, hepatosplenomegaly, and cytopenia-most commonly, thrombocytopenia and anemia. It is characterized by proliferation and activation of benign histiocytes, causing dysfunction of various organs. Herein, we report on a 5-month-old boy whose clinical picture and laboratory findings were consistent with cytomegalovirus infection-associated hemophagocytic syndrome. The patient was successfully treated with intravenous administration of immune globulin and ganciclovir. He remained well 6 months later.
