Most of the signs appear either de novo or have to be elicited by the physician. It refers to important physical finding or observation made by the physician when examining the patient. In this article, we have included total 154 signs including clinical, dermoscopic, and histopathological signs. We have divided them in 13 groups including signs seen in infectious conditions, vesiculobullous disorders, papulosquamous disorders, dermatitis, connective tissue diseases, and diseases of appendages for the ease of readers.
