Hemophagocytic lymphohistiocytosis (HLH) causes multiorgan failure due to the release of multiple cytokines mediating widespread inflammation. We present a patient with multiple myeloma on maintenance chemotherapy with the anti-CD38 monoclonal antibody daratumumab after autologous stem cell transplant (ASCT) who developed fatal HLH secondary to Ehrlichiosis.
