Pyoderma Gangrenosum

  • Inbal Sander


Pyoderma gangrenosum (PG) is a painful ulcerating neutrophilic dermatosis which primarily involves the skin, commonly the lower legs or sites of prior trauma (pathergy); approximately half of cases develop in patients with an underlying systemic disease, most commonly inflammatory bowel disease. Less common associated diseases include inflammatory arthritis, hematologic malignancies and monoclonal gammopathy (most often IgA).
