[Primary hyperlipoproteinemia in childhood (author's transl)].

: Type V hyperlipoproteinemia is an unusual entity in children. Only 6 cases have been described so far to our knowledge. Authors present a 9 year old male that came for diagnosis of a hepatosplenomegaly. There was no evidence of abdominal pain, xanthomas or pancreatitis. Secondary disorders such as uncontrolled insulinopenic diabetes mellitus, glycogen storage disease, administration of estrogen compounds, nephrotic syndrome or uremia, and dysglobulinemias were excluded. His father presented the same lipoprotein pattern suggesting a dominant mode of inheritance. The administration of heparin showed a good response of serum proteinlipase.
