[Pyoderma gangrenosum following AICD implantation: differential diagnosis to necrotizing fasciitis].

Pyoderma gangrenosum is rarely seen in the surgical disciplines. In the described case the patient was initially diagnosed with necrotizing fasciitis and admitted to the intensive care unit suffering from septic shock. The automated implantable cardioverter defibrillator (AICD), the suspected focus for infection, had already been removed. Following weeks of broad spectrum antibiotics and wound debridement without clinical improvement the alternative diagnosis of pyoderma gangrenosum was reached. Consequently the patient was treated with immunosuppressive therapy and his condition improved rapidly such that he was ultimately discharged to rehabilitation.
