Cholesterosis Cutis refers to the deposition of cholesterol in the skin, resulting in yellowish lesions. While there are no direct synonyms for this condition, it can be described as a type of xanthoma or a type of lipid disorder. Xanthomas are yellowish growths that occur in various tissues of the body due to the accumulation of cholesterol, triglycerides, and other lipids. Hypercholesterolemia, hyperlipidemia, or dyslipidemia are also used interchangeably with lipid disorders, which refer to abnormalities in lipid metabolism that can lead to the accumulation of lipids in various tissues, including the skin. Cholesterosis Cutis is most commonly associated with familial hypercholesterolemia, a genetic condition that causes high levels of cholesterol in the blood.
