Pyoderma gangrenosum (PG) is typified by tender, painful, rapidly enlarging cutaneous ulcers with raised, violaceous, undermined borders and a necrotic base. The area of ulceration is often surrounded by an inflammatory erythematous areola. There is frequently associated systemic disease,1 such as inflammatory bowel disease (IBD), arthropathy, benign monoclonal gammopathy, or malignancy.2
