Eruptive xanthoma: The sudden eruption on the skin of crops of pink papules (firm pea-sized bumps) with a creamy center. They may appear on the hands, feet, arms, legs and buttocks. The papules may be pruritic (itchy).
Eruptive xanthoma is due to high concentrations of plasma triglycerides, as occurs with uncontrolled diabetes. The xanthomas usually disappear when the underlying condition is treated, as when the diabetes comes under control.
Also known as diabetic xanthoma or tuberoeruptive xanthoma.
