Fatal missed case of hemophagocytic lymphohistiocytosis co-infected with parvovirus B19 and Epstein-Barr virus in an infant: test hyperferritinaemia early.

Hemophagocytic lymphohistiocytosis (HLH) triggered by Parvovirus B19 and Epstein-Barr virus co-infection is rare and unknown in infants. A 2-month-old male infant with fever, rash, bicytopenia and hepato-splenomegaly died owing to diagnostic dilemmas. Hence simply testing for hyperferritinaemia and hypertriglyceridemia/hypofibrinogenemia could diagnose HLH early while robust treatment be life-saving.
