Inflammatory bowel diseases may be associated with extraintestinal manifestations. Among them, mucocutaneous manifestations are relatively common, often difficult to diagnose and treat, and may complicate the course of the underlying disease. Local and systemic immunosuppressive drugs are used in inflammatory bowel disease-related mucocutaneous manifestation treatment, and sometimes dermatological involvement can be improved with effective treatment of inflammatory bowel disease. It should be considered that biological drugs used for the treatment of inflammatory bowel disease may also cause dermatological disorders. A detailed dermatological evaluation is essential in all inflammatory bowel disease patients, particularly biologic therapy candidates. Interdisciplinary cooperation between dermatologists and gastroenterologists is required in diagnosis, follow-up, and treatment. This article aims to review the current literature on the diagnosis and treatment of mucocutaneous disorders that may develop in the course of inflammatory bowel disease.
