Hemophagocytic syndrome

Hemophagocytic syndrome - a classification of rare, non neoplastic, proliferative disorders of the hematologic system. Primary or familial hemophagocytic lymphohistiocytosis (hlh) is inherited with an autosomal recessive pattern with five known subtypes differentiated by specific genetic mutations. Secondary manifestation of hlh is usually seen in hyperactivated immunologic states such as infection, autoimmune disease or malignancy. Histiocytes in the bone marrow, spleen or lymph nodes become activated to the point that phagocytosis proceeds unchecked. Clinical signs usually present within the first decade and include fever, jaundice, hepatosplenomegaly, lymphadenopathy and skin rash. Prompt initiation of treatment improves survival though prognosis remains poor even with intervention.
