Crimean-Congo haemorrhagic fever (CCHF) is a severe disease with a case fatality of 2.8 to 80%. A patient dwelling in an endemic region for CCHF was admitted with fever preceding bleeding diathesis and pancytopenia. Despite no history of tick exposure, CCHF was highly suspected. With an oral ribavirin therapy, clinical and laboratory improvements were obtained. The diagnosis was confirmed by detection of IgM antibody to CCHF virus and positive RT-PCR. Although the main pathogenesis of CCHF infection is not elucidated yet, haemophagocytosis, a symptom rarely reported in viral haemorrhagic fevers, was observed in this case. Haemophagocytosis is suggested to have a role in the development of pancytopenia in CCHF, the mechanism of which still needs to be investigated, probably with cytokine studies. Together with clinical symptoms and patient history, haemophagocytosis may be an indicator for CCHF.
