Brucellosis-Induced Hemophagocytic Lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a fatal syndrome, which can be primary or triggered by a systemic disease or an infection. The commonly reported infectious causes of secondary HLH include Epstein-Barr virus (EBV), cytomegalovirus (CMV), mycobacterium, and leishmaniasis among other infections. In this case report, we report a 50-year-old woman with brucellosis-related HLH after presenting with prolonged fever, hepatosplenomegaly, and cytopenia.
