Berardinelli-Seip syndrome is a rare autosomal recessive disease characterized by
inadequate metabolism and inefficient storing of lipids in fat cells, generating
accumulation of fat in organs such as the liver, spleen, pancreas, heart, arterial
endothelium and skin. Classically, patients manifest generalized lipoatrophy at birth
or until 2 years of age, and in adolescence usually develop marked insulin resistance
with rapid progression to diabetes and dyslipidemia. We report the case of a
17-year-old Berardinelli-Seip syndrome patient with eruptive xanthoma associated with
severe hypertriglyceridemia. It is worth noting Eruptive xanthoma as a dermatological
manifestation that is not generally highlighted in the reports of cases of this
genetic metabolic disorder.
