title: Psoriasiform and pustular eruption induced by infliximab.
abstract: Although antitumor necrosis factor (anti-TNF)-alpha therapy provides beneficial effects on various chronic inflammatory skin diseases including psoriasis, cutaneous side-effects have also been reported. We describe four patients who showed psoriasiform eruption following anti-TNF-alpha therapy (infliximab) for Crohn's disease. In all patients, Crohn's disease had responded well to infliximab. Three patients developed plaque-type psoriasiform eruption on the trunk and four extremities, while one patient showed pustular eruption on the palms and soles accompanied with plaque-type psoriasis. In all these patients, skin lesions subsided with topical application of corticosteroid ointment or psoralen plus ultraviolet A treatment.
