Pyoderma gangrenosum after breast surgery: a systematic review

Post-surgical pyoderma gangrenosum (PSPG) is a rare inflammatory skin disorder of unknown etiology. Given its similar presentation to wound infection and lack of reliable diagnostic tests as well as pathognonic clinical features, PSPG is difficult to diagnose. Aim of this review was to identify factors contributing to PSPG in order to aid with timely diagnosis and appropriate therapy.
