Pyoderma gangrenosum is a neutrophilic, non-infectious, and progressive dermatosis. Superficial granulomatous or vegetative variety is advertised as the least typical. Diagnosis is difficult even for the dermatologist due to its large clinical spectrum. It has a lower association with systemic involvement and excellent response to topical corticosteroids or short oral courses of them. We present a 32-year-old male with no history of importance who presents two erythematous, warty and crusty plaques on the leg, asymptomatic, of two months of evolution; histopathology compatible with vegetative pyoderma gangrenosum. He had a good response to treatment with no recurrences 13 years after diagnosis.
