The association of psoriasiform rash with anti-tumor necrosis factor (anti-TNF) therapy in inflammatory bowel disease: A single academic center case series

27 cases of anti-TNF associated psoriasiform lesions are reported. Discontinuation of anti-TNF treatment is unnecessary in the majority. Dermatologic improvement was achieved in the majority with a subsequent anti-TNF, suggesting anti-TNF induced psoriasiform rash is not necessarily a class effect.
