Pyoderma Gangrenosum:Recognition and Management.

Pyoderma gangrenosum is an unusual cause of skin ulcerations that wound specialists must be prepared to recognize. There is no diagnostic test since it is a diagnosis of exclusion, and if the disease is not recognized it can quickly become much worse. Pathergy, whereby a lesion begins or worsens due to trauma, such as a scrape, bite, debridement, surgery, or biopsy, is seen with pyoderma and requires special consideration. This case series and review will summarize the salient features of pyoderma and its treatment with an emphasis on the controversial role of surgery with pyoderma.
