Department of Dermatology, Turin University, Italy.

The 5th case of papular xanthoma is reported. This entity can be differentiated on the basis of clinical and histological features: normolipidemic, nonconfluent, eruptive xanthomas located on the face, trunk and mucous membranes with no internal involvement. Histologically there are foamy cells and Touton giant cells without an inflammatory or histiocytic component. Electron microscopy shows macrophages packed with free lipidic vacuoles and lacking specific markers.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy

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.
