Overview
Hemophagocytic lymphohistiocytosis (HLH) is an uncommon hematologic disorder in which the immune system produces too many activated immune cells (lymphocytes) called T cells, natural killer cells, B cells, and macrophages (histiocytes). Excessive amounts of immune system proteins called cytokines are also produced.
