Skin reactions caused by centipedes: Long‐lasting necrosis and late‐onset local reaction

Abstract

Centipedes are nocturnal, fast-moving, multisegmented arthropods [1, 2]. To date, approximately 20 genera and 3000 species have been identified; Scolopendra is the most wellknown and largest centipede with a length ranging from 8 to 20 cm [1, 3]. Centipedes favor tropical and warm temperate regions [3]. Accidental encounters usually take place during summer, at night-time, and in indoor settings [4]. Centipedes inject venom through their sharp, stinging structures called forcipules, which are derived from their first pair of legs [2]. It is therefore reasonable to refer to a "centipede sting" or "centipede envenomation" rather than a "centipede bite" [2, 3]. Centipede sting reactions are rarely reported in the dermatological literature [1], probably because they are usually mild. Here we report on two patients who presented with peculiar dermatologic reactions following centipede envenomation.
