Pyoderma gangrenosum complicating bilateral mammaplasty.

Pyoderma gangrenosum (PG) is an idiopathic necrotising cutaneous disorder. It is associated with systemic diseases like inflammatory bowel disease, monoclonal gammopathy, arthritides and haematological malignancy. PG occurring at sites of trauma, a phenomenon called pathergy, is well described. One of the manifestations of pathergy is PG occurring at sites of surgery. We describe a case of PG at sites of reduction mammaplasty and review the literature so far. Copyright 2000 The British Association of Plastic Surgeons.
