Looking at the “Inverse” in dermatology

Abstract

The predilection of skin disorders for characteristic sites and awareness of these sites is very important for clinical diagnosis. However, certain subtypes of common dermatological conditions can involve sites opposite to that of the classical presentation. These subtypes are named using the prefix “inverse” or the suffix “inversus/inversa” in the literature. These variants may pose a diagnostic challenge to residents and knowledge of the various “inverse” dermatological conditions and phenomena in the literature is of great significance.
