Sea-Blue Histiocyte Syndrome

A congenital disease caused by an inborn error involving APOLIPOPROTEINS E leading to abnormal LIPID METABOLISM and the accumulation of GLYCOSPHINGOLIPIDS, particularly SPHINGOMYELINS in the HISTIOCYTES. This disorder is characterized by SPLENOMEGALY and the sea-blue histiocytes in the spleen and bone marrow after May Grunwald staining.

Year introduced: 1984
