Tuberous xanthomas in sitosterolemia.
Sitosterolemia is an autosomal recessive lipid disorder in which plasma plant sterol levels are extremely elevated and cholesterol levels are often elevated but may be normal. Clinically sitosterolemia is characterized by xanthomas, premature vascular disease, and arthritis. Adolescent boys and girls with sitosterolemia are susceptible to fatal cardiac events. Dermatologists may have a vital role in the diagnosis of this rare but serious condition because early detection and treatment are important in preventing the associated atherosclerotic heart disease. We present a 7-year-old girl with sitosterolemia and tuberous xanthomas.
