Xanthomas are yellowish, fatty deposits that can appear on the skin, often associated with high levels of lipids in the blood. They can vary in size and shape, commonly found on the elbows, knees, and eyelids. Xanthomas can indicate underlying health issues, such as hyperlipidemia or other metabolic disorders. These skin lesions are not harmful themselves but may signal the need for medical evaluation. Treatment typically focuses on managing the underlying condition, which may involve lifestyle changes, dietary adjustments, or medications to lower lipid levels. Regular check-ups can help monitor and address any related health concerns.
