My disapprobation is twofold.

  1. Presently there is no evidence to discredit the "eruptive xanthoma as the sole manifestation of an elevated triglyceride fraction,"2 and it being "characteristic of hyper pre-β-lipoproteinemia."3 In fact, clinical analysis of the eruptive xanthoma shows it to contain "more free fatty acids and less cholesterol esters than the tuberous and tendinous xanthomata."4 It would thus follow that the other forms of xanthoma, eg, the tuberous, are associated with hypercholesterolemia.
