This accumulation of cholesterol can take the form of either xanthomatosis or atherosclerosis. Cholesterol is carried in lipoproteins, particularly low-density lipoprotein (LDL) β-lipoprotein), very low-density lipoprotein (VLDL) (prebeta lipoprotein), and high-density lipoprotein (HDL) (α-lipoprotein). Various forms of xanthomas commonly develop in association with elevations in LDL and VLDL levels1 while HDL is thought to exert a protective effect against tissue cholesterol deposition by serving as a vehicle for transport of cholesterol from peripheral cells back to the liver. Low plasma concentration of HDL results in a defects of removal
