title: Papular xanthoma. Clinical, histological and ultrastructural study.
abstract: 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.
