Comparison of pyoderma gangrenosum and hypertensive ischemic leg ulcer Martorell in a Swiss cohort

Abstract

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis presenting with painful and sterile skin ulcerations (1). Its aetiology remains largely unknown although an autoinflammatory background seems possible. Several comorbidities as well as triggering factors such as surgery, trauma or pharmacological therapies have been associated with the development of PG (2). Different topical and systemic treatments are recommended for PG, most commonly topical steroids or calcineurin inhibitors as well as systemic steroids, dapsone, infliximab and others, as well as by our group and others canakinumab and ustekinumab (3, 4).
