Abtract Pyoderma gangrenosum (PG) is an uncommon cutaneous disease of unknown etiology. In 50 percent of affected patients, PG is associated with systemic disease including inflammatory bowel disease, arthritis, and hematologic malignancies. 1 Diagnosis of PG is based on clinical presentation, histopathology and on the exclusion of other diseases that can produce clinically similar lesions, e.g. infection, vasculitis, malignancy, collagen vascular diseases, diabetes, and trauma. Four variants of PG have been described: ulcerative, pustular, bullous, and vegetative. 2 We report a woman with renal failure who developed PG in the absence of any obvious triggering trauma in a distinctive unilateral crop just distal to an arteriovenous dialysis shunt.
