Diffuse plane idiopathic normolipemic xanthoma with hypersplenism

Diffuse plane normolipemic xanthoma is a rare disease, of a group of clinical syndromes called histiocytoses, characterized by the presence of yellowish or yellow-orange plaques, distributed symmetrically on the cutaneous surface and usually accompanied by xanthelasma. It affects mainly adults and it may cause discrete changes in serum lipids. The case of an 85-year-old female patient who has been showing extensive asymptomatic yellow-orange plaques in the trunk and abdomen for a year is reported. Laboratory tests did not show an increase in serum lipids or the occurrence of reticuloendothelial disorders.
