Abstract
Infliximab, the monoclonal antibody to tumor necrosis factor, is indicated for refractory luminal and fistulizing Crohn's disease and rheumatoid arthritis. Infliximab treatment has adverse events including infusion reactions, op-portunistic infections, and the potential for the event such as reactivation of latent tuberculosis. Cutaneous adverse reactions of TNF-α agents include skin rash, urticaria, pruritus, lupus-like eruption, and injection site reactions. Most of all, psoriasis or psoriasiform dermatitis induced by infliximab treatment for Crohn's disease is rarely reported in Korea. We report a case of psoriasis induced by infliximab treatment for Crohn's disease with a review of world literature.
