We present the case of a 10-year-old boy suffering from homozygous familial hypercholesterolemia with generalized atherosclerosis and large xanthomas. The case impressively demonstrates the potential of low-density lipoprotein cholesterol lowering to rapidly regress pathologic cutaneous manifestations of hypercholesterolemia.
