Hyperlipidemia Signs (Xanthomas, Tendinous Xanthoma, Corneal Arcus)

Hyperlipidemia Signs (Xanthomas, Tendinous Xanthoma, Corneal Arcus) are visible clues that indicate high levels of fats, such as cholesterol, in the blood. These signs affect the skin, tendons, and eyes, showing up as yellowish bumps or rings. Xanthomas are fatty deposits that can appear on the skin, while tendinous xanthomas form on tendons, often causing lumps. Corneal arcus is a gray or white ring around the cornea of the eye. These signs suggest an underlying problem with how the body processes fats, which can increase the risk of heart disease and stroke. Recognizing these signs helps identify people who may need further testing and treatment to protect their heart health.

Hyperlipidemia Signs (Xanthomas, Tendinous Xanthoma, Corneal Arcus) represent clinical manifestations of lipid metabolism disorders characterized by elevated plasma levels of cholesterol and triglycerides. These signs result from the deposition of lipid-laden macrophages in the skin, tendons, and corneal stroma. Xanthomas are often associated with familial hypercholesterolemia or other genetic dyslipidemias caused by mutations in genes such as LDLR or APOB. Tendinous xanthomas typically involve the Achilles tendon and extensor tendons of the hands and are highly specific for familial hypercholesterolemia. Corneal arcus, a lipid ring around the cornea, can be seen in both familial and acquired hyperlipidemia, especially in older adults. These signs are important because they indicate an increased risk of atherosclerosis and premature cardiovascular disease due to chronic lipid elevation.
