Xanthomas 是体内的脂肪沉积物。虽然它们大多是良性的，但常常是全身性疾病的重要提示。并非所有胆固醇或血脂水平升高的人都会出现黄瘤，但一旦发现黄瘤，往往提示潜在的代谢异常。
Xanthomas are localized lipid deposits within an organ system. Although innately benign, they are often an important visible sign of systemic diseases. Not all patients with hyperlipidemia or hypercholesterolemia develop xanthomas. However, the presence of xanthomatous lesions can serve as a unique and important clinical indicator of these metabolic states.
