Eruptive Xanthoma

Eruptive xanthomas, a distinct dermatological manifestation in patients with diabetes, underscore the relationship between systemic diseases and skin health. Manifesting as benign lesions made up of foam cell clusters in the skin, tendons, and subcutaneous tissues, they serve as markers for hyperlipidemias, often in the context of poorly controlled diabetes mellitus. Eruptive xanthomas typically emerge as orange-yellow papules with a firm texture and an erythematous border, primarily appearing on the buttocks, posterior thighs, elbows, and the lumbar region—areas especially prone to increased pressure. The development of these lesions points to a dysfunction in lipid transport mechanisms, leading to an abnormal accumulation of lipids in skin tissues due to factors like endothelial dysfunction, disturbances in microcirculation, and a genetic predisposition to lipid metabolism disorders. Controlling hyperlipidemia and diabetes through dietary changes, weight control, exercise, and pharmacotherapy is crucial for the regression of xanthomas.
