Pyoderma gangrenosum (PG) is a rare autoinflammatory skin disorder, which is characterised by rapidly developing and tender cutaneous ulcers. The treatment of PG is challenging. Palmoplantar pustulosis (PPP) is also an autoinflammatory dermatosis with sterile pustules on the palms and/or the soles. We demonstrated a 68-year-old patient with coexisting autoinflammatory diseases including PG, 1-year history of plaque psoriasis and PPP, recovered after treatment with adalimumab. We also reviewed published reports of PG-associated autoinflammatory syndromes with adalimumab.
