[Superficial granulomatous pyoderma: report of a case of an uncommon variant of pyoderma gangrenosum]

Pyoderma gangrenosum is a rare idiopathic skin disease. It affects mainly adults, and only 4% of the cases are diagnosed on children and adolescents. There are four clinical forms of pyoderma gangrenosum: ulcerative, pustular, bullous, and vegetative (superficial granulomatous pyoderma). Superficial granulomatous pyoderma is considered the most benign and uncommon form of the disease. Patients who have undergone surgical procedures may occasionally present pyoderma gangrenosum manifestations on the surgical site. A case of a five-year-old child, victim of burn, who presented superficial granulomatous pyoderma on the skin graft donor sites is reported.
