Dear Editor,Hemophagocytic lymphohistiocytosis (HLH) is a rare complication of chimeric antigen receptor T-cell (CAR-T) therapy [1,2,3]. With the increasing use of CAR-T therapy in treating hematological malignancies, the unique phenomenon of CAR-T-associated HLH (carHLH) is increasingly recognized. Albeit rare, reported rates vary from 1–3% to 35% depending on the underlying disease, patient population and the CAR-T product [1,2,3].
