Xanthomas are most closely associated with which metabolic disturbance?

• A. Hypercholesterolemia
• B. Hyperkalemia
• C. Hypoglycemia
• D. Hyponatremia

Answer: (A)

Xanthomas appear when lipid-laden macrophages deposit in the skin due to elevated blood lipids, most commonly cholesterol. This makes hypercholesterolemia the best match, as high cholesterol (often from conditions like familial hypercholesterolemia) leads to these cholesterol-rich skin deposits. While very high triglycerides can cause some forms of xanthomas, the classic association emphasized in exams is hypercholesterolemia. The other listed disturbances—electrolyte imbalances or low blood sugar—do not typically produce xanthomas.
