Possible applications of videodermatoscopy beyond pigmented lesions

Videodermatoscopy (VD) is a noninvasive technique which involves in vivo skin observation by a video camera equipped with lenses that currently allow magnifications ranging from × 4 to × 1000. The images obtained are visualized on a highdefinition monitor and may be stored on a personal computer, in order to identify and compare changes over time. VD is widely used in the differential diagnosis of pigmented skin lesions by epiluminescence microscopy, which involves the application of a liquid (oil, alcohol, or water) to the skin to eliminate light reflection; recently, new systems have used polarized light, obtaining similar results without the need for liquids. VD allows the rapid, magnified observation of the skin surface, and has been used in other areas of dermatology, alone or with epiluminescence microscopy, with variable results.
