{Reference Type}: Case Reports {Title}: Case report-Rapid regression of xanthomas under lipoprotein apheresis in a boy with homozygous familial hypercholesterolemia. {Author}: Katzmann J;Schürfeld C;März W;Laufs U; {Journal}: J Clin Lipidol {Volume}: 12 {Issue}: 4 {Year}: Jul 2018 0 {Factor}: 5.365 {DOI}: 10.1016/j.jacl.2018.05.001 {Abstract}: Xanthomas are visibly deforming cholesterol deposits that develop after long-term exposure to high serum low-density lipoprotein cholesterol concentrations. 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.
