Xanthelasma eosin and hematoxylin stain A xanthelasma is a sharply demarcated yellowish collection of cholesterol underneath the skin, usually on or around the eyelids. Strictly, a xanthelasma is a distinct condition, being called a<unk>  only when becoming larger and nodular, assuming tumorous proportions. Still, it is often classified simply as a subtype of<unk> .<unk>  tuberosum<unk>  tuberosum (also known as tuberous<unk>  is characterized by<unk> s located over the joints.<unk>  tendinosum<unk>  tendinosum (also tendon<unk>  or tendinous<unk>  is clinically characterized by papules and nodules found in the tendons of the hands, feet, and heel. Also associated with familial hypercholesterolemia (FH). Eruptive<unk>  Eruptive<unk>  (ILDS E78.220) is clinically characterized by small, yellowish-orange to reddish-brown papules surrounded by an erythematous halo that appear suddenly all over the body, especially the hands, buttocks, and the extensor surfaces of the extremities. It tends to be associated with elevated triglycerides<unk>  planum<unk>  planum (ILDS D76.370), also known as plane<unk> , is clinically characterized by bands or rectangular plates (macules) and plaques in the dermis spread diffusely over large areas of the body. Palmar<unk>  Palmar<unk>  is clinically characterized by yellowish plaques that involve the palms and flexural surfaces of the fingers. Plane<unk> s are characterised by yellowish to orange, flat macules or slightly elevated plaques, often with a central white area which may be localised or generalised. They often arise in the skin folds, especially the palmar creases. They occur in hyperlipoproteinaemia type III and type IIA, and in association with biliary cirrhosis. The presence of palmar<unk> ta, like the presence of tendinous<unk> ta, is indicative of hypercholesterolaemia. Tuberoeruptive<unk>  Tuberoeruptive<unk>  (ILDS E78.210) is clinically characterized by red papules and nodules that appear inflamed and tend to coalesce. Tuberous<unk> ta are considered similar, and within the same disease spectrum as eruptive<unk> ta. Other types Other types of<unk>  identified in the Medical Dictionary include: *<unk>  diabeticorum: a type of eruptive<unk> , often with severe diabetes. *<unk>  disseminatum: a rare<unk>  consisting of non-X histiocytes on flexural (folded) surfaces, associated with diabetes insipidus. * Verrucous<unk> , or histiocytosis Y: a papilloma of the oral mucosa and skin whereby the connective tissue under the epithelium contains histiocytes.
