CONT

Hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially fatal disease of normal but overactive histiocytes and lymphocytes that commonly appears in infancy, although it has been seen in all age groups. ... The pathological hallmark of this disease is the aggressive proliferation of activated macrophages and histiocytes, which phagocytose other cells, namely RBCs [red blood cells], WBCs [white blood cells], and platelets, leading to the clinical symptoms. The uncontrolled growth is nonmalignant and does not appear clonal ... The spleen, lymph nodes, bone marrow, liver, skin, and membranes that surround the brain and spinal cord are preferential sites of involvement.

PHR

Acquired, familial, primary, secondary hemophagocytic lymphohistiocytosis.
