GATA2 Mutation Underlies Hemophagocytic Lymphohistiocytosis in an Adult with Primary Cytomegalovirus Infection

We report a case of a 27-year old woman with persistent fever and pancytopenia who had multiple episodes of a hemophagocytic lymphohistiocytosis (HLH) like condition. The criterion for HLH was satisfied; primary cytomegalovirus (CMV) infection was identified as the cause. Further examination revealed a GATA binding protein 2 mutation. Reports of GATAs deficiency presenting with HLH after primary CMV infection is very limited. As early recognition and diagnosis will improve patients' outcomes, internists and infectious disease specialists should be aware of this disease.
