Pyoderma gangrenosum in a battered child.

Abstract

Pyoderma gangrenosum is an uncommon cutaneous ulceration, which continues to be a difficult disorder to diagnose and treat. A pediatric case of pyoderma gangrenosum with no associated systemic disorder is presented. The disease was precipitated by physical trauma. The disease was controlled with systemic corticosteroid therapy and then the wound was successfully covered with a split-thickness skin graft from the thigh without any healing problem at the donor site. Although pathergy is well described in the etiopathogenesis of the disease, this is the first case reported that was precipitated after physical assault.
