A Compendium of Common Signs in Dermoscopy, Trichoscopy, and Onychoscopy

Abstract

Epiluminescence microscopy, also known as dermoscopy (or dermatoscopy), is a noninvasive tool which helps in identifying features which may not be visible to the unaided eye. Dermoscopic signs in dermatology, trichology, and onychology are evolving concepts for ease in diagnosis of certain dermatological disorders. Although all these signs have been published in different articles and texts as a scattered information, this article intends to consolidate the pertinent signs and create an easy reference for dermatologists in order to establish prompt diagnosis during their busy schedules.
