Pustular psoriasis induced by infliximab.

Pustular psoriasis is an uncommon variant of psoriasis characterized by widespread pustules on an erythematous background. Recent reports document the efficacy of immunobiologic agents such as infliximab in the treatment of pustular psoriasis. We present a patient that developed cutaneous and pathologic changes consistent with pustular psoriasis while receiving treatment with infliximab for chronic ulcerative colitis.
