The chik sign in dengue

Abstract

The chik sign is considered to be one of the most common cutaneous features of chikungunya fever and has been considered unique to this disorder. It consists of brownish hyperpigmentation involving the nose. We report a case of a 3‐year‐old boy with dengue infection who presented with macular hyperpigmentation of nose simulating the chik sign. Hyperpigmentation is an unusual cutaneous manifestation in cases of dengue.
