Eruptive xanthomas as a cutaneous manifestation of hypertriglyceridemia: a case report.

A 28-year-old veteran presented to the Wilford Hall dermatology clinic in San Antonio, Texas, with a six-month history of a rash that his primary care physician diagnosed as molluscum contagiosum. The rash consisted of clusters of 3 to 6mm yellowish papules with erythematous borders that concentrated on the extensor surfaces of his extremities, lower back, and buttocks. A biopsy determined that the patient had a case of eruptive xanthoma. Subsequent laboratory testing revealed that the patient had a type IV familial hyperlipidemia with a triglyceride count of 1718mg/dL.
