Paederus dermatitis: an outbreak on a medical mission boat in the Amazon

Jere J Mammino. J Clin Aesthet Dermatol. 2011 Nov.

Abstract

Paederus dermatitis is a peculiar, irritant contact dermatitis characterized by a sudden onset of erythematobullous lesions on exposed areas of the body. The disease is provoked by an insect belonging to the genus Paederus. This beetle does not bite or sting, but accidental brushing against or crushing the beetle over the skin provokes the release of its coelomic fluid, which contains paederin, a potent vesicant agent. This article describes this dermatitis, which occurred in three healthcare personnel aboard a medical mission boat on the Amazon River. The epidemiology and pathogenesis of paederus dermatitis is reviewed as well its treatment and prevention.
