[Scanning electron microscopic studies of diseases fingernails by means of a casting technic].

By a cast method (silicone resins) which allows a form-fitting reprint of nail-plate relief are made scanning electron microscopic studies of healthy and sick nails. In this way a form-fitting restitution of the surface-relief is guaranteed up to magnifications of 5000:1. Thus it is possible to get a better impression of the affected nail-structure. The exactitude of this nail-structure-representation cannot be reached by normal light microscopy. This method is very simple and quickly to use. Nail-changes in onychoschizia, subungual hematoma and in senile nails are shown.
