title: Clinical applications of scanning electron microscopy and X-ray microanalysis in dermatology.
abstract: Scanning electron microscopy is frequently applied to dermatological problems, as is evident from a review of the recent literature. In this tutorial, preparation methods and new techniques allowing experimental studies on the integumentary system are emphasized. Quantitative analysis in the electron microscope by use of energy-dispersive X-ray microanalysis ( EDX ) has become an important accessory technique. EDX can, for instance, be used to study problems involving physiological changes induced in skin by agents causing contact reactions. Recently, it has been shown that treatment with DNCB, chromate and nickel causes changes in elemental distribution in guinea-pig skin. In addition, elemental uptake in the integumentary system and in pathological inclusions in skin can be analyzed.
