[Lipid composition of cutaneous lesions in different types of xanthomatosis]. 1977

J Ferrando, and A Corominas Vilardell

Twenty one specimens of cutaneous xanthomas from different types of hyperlipoproteinaemic and normolipidemic xanthomatosis were obtained and analyzed by thin layer chromatography. After separation and development, the areas were determinated by densitometry, and the results are given in percentages for each development. Acording to the results, the following data are of interest: -- Recents xanthomas have greater amount of lipids. -- Cholesterol esters (EC) are prevalent in xanthomas and in normal skin the triglycerides fraction. -- Monoenoic esters (EM) are prevalent on EC chromatography, like in normal skin. -- Finally, there are not significant variations between lipid composition of xanthomas in the different Xanthomatosis.

UI	MeSH Term	Description	Entries
D008055	Lipids	A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D002855	Chromatography, Thin Layer	Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose.

D004817	Epidermis	The external, nonvascular layer of the skin. It is made up, from within outward, of five layers of EPITHELIUM: (1) basal layer (stratum basale epidermidis); (2) spinous layer (stratum spinosum epidermidis); (3) granular layer (stratum granulosum epidermidis); (4) clear layer (stratum lucidum epidermidis); and (5) horny layer (stratum corneum epidermidis).

D014973	Xanthomatosis	A condition marked by the development of widespread xanthomas, yellow tumor-like structures filled with lipid deposits. Xanthomas can be found in a variety of tissues including the SKIN; TENDONS; joints of KNEES and ELBOWS. Xanthomatosis is associated with disturbance of LIPID METABOLISM and formation of FOAM CELLS.
