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. Fever, Hepatosplenomegaly, Pancytopenia, Lymphadenopathy, and rash often comprise the initial presentation. Primary HLH also occurs in some closely related inherited diseases.
X-rays, CT scans, ultrasounds or MRIs may be performed.
