Eruptive Xanthoma

Eruptive xanthomas arise in the setting of elevated levels of chylomicrons, often occurring in cases of uncontrolled diabetes mellitus, alcohol dependence, medication use (eg, isotretinoin), and familial hyperlipidemias (Frederickson types I, IV, and V). Classically, lesions present as multiple smooth red-yellow papules that occur in eruptive crops on the buttocks and extensor surfaces of the extremities and may koebnerize.
