Nosocomial nasal myiasis owing to Cochliomyia hominivorax: a case in French Guiana.

Abstract The larval stages of the fly Cochliomyia hominivorax are responsible for myiasis, which primarily affects wounds. We report the case of a bed-ridden patient with dementia who developed right nasal myiasis during his stay at Cayenne Hospital. Progression was favorable, but the nasal pyramid was partially destroyed. In zones where this fly is endemic, particular attention should be given to hospitalized patients with wounds and consciousness problems.
