Eruptive xanthoma: a case report.

Eruptive xanthomatosis is a papular skin disorder resulting from hyperlipidemia, specifically hypertriglyceridemia. It is characterized by yellowish red papules concentrated on extensor surfaces of the arms and legs. The hyperlipidemia responsible for this disorder can be caused by a primary genetic defect, a secondary disorder, or both. Eruptive xanthomas often rapidly resolve after treatment of the hyperlipidemia has begun.
