Nonmalignant Dermatologic Disorders in Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is associated with extraintestinal manifestations that can affect multiple body systems. Extraintestinal manifestations (EIMSs) are seen in up to 50% of patients with IBD. Skin involvement is particularly common occurring in up to 15%-20% of patients. Skin reactivity presents in multiple forms with unique pathology. Therapy for IBD also may affect the skin directly through inflammatory processes or indirectly because of skin infections. This review will concentrate on the most common nonmalignant dermatologic conditions associated with IBD with a focus on prevalence, diagnostic approaches, and management strategies.
