Adalimumab-induced psoriatic alopecia/alopecia areata-like reaction in a patient with Crohn's disease

摘要

Anti-tumor necrosis factor (anti-TNF) agents have been successfully used to treat both chronic idiopathic inflammatory bowel disease and other immune-mediated chronic diseases, but they can also induce a wide array of cutaneous reactions, including new-onset psoriasis and alopecia. We report a case of alopecia associated with psoriasiform skin lesions in a patient on adalimumab treatment for Crohn's disease.
