Pinpoint skin lesions in a familial hypercholesterolaemia homozygote.

UNLABELLED: The case is reported of a 2-y-old girl referred to the outpatient lipid clinic because of a tiny cutaneous xanthoma on the dorsum of the left foot and a family history of hyperlipidaemia and coronary heart disease (CHD). Fasting serum total cholesterol levels were remarkably high (27.1 mmol l(-1), 1050 mg dl(-1)) and DNA analysis confirmed homozygous familial hypercholesterolaemia (class II mutation). Serum lipids were not affected by dietary intervention and cholestyramine treatment, so low-density lipoprotein apheresis was scheduled to commence at the age of 4 y.

CONCLUSION: An early lipid profile determination should be performed in children with a family history of premature CHD, since the physical examination may be unremarkable even in cases of severe hyperlipidaemia during the first years of life.
