Síndrome de Wells: uma dermatose reacional Wells syndrome: a reactional dermatosis

Wells syndrome is a rare skin disorder clinically characterized by hardened plaques similar to cellulite. Its pathogenesis is unknown, but the possibility of local hypersensitivity has been proposed. We report the case of a six-year-old who presented with erythematous and edematous lower limbs, whose histopathology showed a mixed infl ammatory infi ltrate with numerous intermingled eosinophils amid eosinophilic collagen degeneration (“fl ame fi gures”). The only abnormality in laboratory tests was eosinophilia. This patient had hypersensitivity to insect bites. There was good response to topical steroids. Wells syndrome is a likely cutaneous condition in reaction to various stimuli, and therefore the necessary investigation should be made. In this patient, insects’ sting seems to have been the triggering factor.
