Hemophagocytic lymphohistiocytosis associated with visceral leishmaniasis.
A 2-year-old child presented with fever and hepatosplenomegaly. Laboratory findings showed pancytopenia, hypertriglyceridemia, hyperferritinemia, and high levels of soluble-IL2 receptors. Initial bone marrow aspiration and biopsy revealed mild hemophagocytosis. A diagnosis of hemophagocytic lymphohistiocytosis was made and appropriate treatment was begun. Repeated marrow aspiration performed because of lack of clinical response revealed Leishmania amastigotes in macrophages in addition to active hemophagocytosis. Treatment with liposomal amphotericin resulted with rapid recovery. Visceral leishmaniasis should be considered in the differential diagnosis of hemophagocytic syndrome.
