A lymph node biopsy showed the features of Kikuchi's disease, with necrosis and histiocytic infiltration without neutrophils. No evidence of tuberculosis was found on staining, culture, or the polymerase chain reaction. Bone marrow biopsy revealed prominent haemophagocytosis, and a diagnosis of haemophagocytic syndrome was reached. The aetiology of haemophagocytic syndrome, and its association with Kikuchi's lymphadenitis, is discussed.
