title: ﻿﻿﻿﻿﻿﻿﻿Post-traumatic Pyoderma Gangrenosum.
abstract: ﻿ ﻿Chronically nonhealing wounds caused by pyoderma gangrenosum (PG) are rare and often misdiagnosed. Since PG has no pathognomonic features, the diagnosis is based on clinical grounds. It is a diagnosis of exclusion and presents a considerable challenge, particularly in the absence of systemic diseases commonly associated with PG. Mistreatment or delayed proper treatment can be harmful to patients. The need to recognize trauma (pathergy) as a potential trigger of PG is important for the optimal management of these wounds. The authors present 5 patients who had PG following different forms of trauma at or near the wound site.﻿.
