Type III hyperlipoproteinemia in a patient with idiopathic hemochromatosis.

A 60-year-old man is reported with idiopathic hemochromatosis and type III hyperlipoproteinemia. Regular phlebotomy therapy and fenofibrate treatment favorably influenced the disorder of iron metabolism and the lipid disease. Evidence is given that both errors of metabolism are independently inherited diseases, although the symptoms of the first (idiopathic hemochromatosis) may aggravate the expression of the second (type III hyperlipoproteinemia).
