Abstract: As a non-invasive and rapid diagnostic tool, dermoscopy has been widely applied to erythematosquamous skin diseases, and has significantly improved the efficiency of clinical work and diagnostic accuracy. Most dermoscopic features of erythematosquamous skin diseases are associated with histopathological changes. Here a consensus was reached on the correlation between the dermoscopic features and the histopathological features of common erythematosquamous skin diseases, in order to improve the understanding of dermatologists on the dermoscopic features of erythematosquamous skin diseases.
