Answer

Severe hypertriglyceridemia may cause skin lesions called xanthomas. Patients may report the appearance of any of the following types of xanthomas:

  • Xanthoma striata palmaris: Orange-yellow discolorations of the palmar creases, which in some cases are raised; considered pathognomonic for dysbetalipoproteinemia

  • Tuberoeruptive xanthomas: Nonpainful, raised, erythematous, nodular lesions approximately 0.5 cm in diameter; may be present on the elbows and knees

  • Tuberous xanthomas: Larger, coalesced tuberoeruptive xanthomas; raised, moderately firm, nontender lesions predominantly on the elbows and knees

  • Tendon xanthomas: Occur infrequently; more common in familial hypercholesterolemia

  • Eruptive xanthomas: Small nodular papules commonly seen over the trunk, buttocks, and thighs; associated with chylomicronemia syndrome
