Name a common extraintestinal manifestation of IBD.

• A. There are no extraintestinal manifestations.
• B. Erythema nodosum as a common extraintestinal manifestation.
• C. Only rheumatologic manifestations occur.
• D. Sarcoidosis is the most common extraintestinal manifestation.

Answer: (B)

Extraintestinal manifestations are common in inflammatory bowel disease and can involve skin, joints, eyes, and liver. Erythema nodosum is one of the most frequent skin manifestations and often mirrors the activity of the bowel disease. It shows up as tender, red nodules on the shins and can occur in both Crohn’s disease and ulcerative colitis. This makes it a classic example of a common extraintestinal manifestation. Other statements aren’t accurate because there are indeed extraintestinal manifestations beyond the gut, and while rheumatologic issues do occur, they’re not the only type, with sarcoidosis not being the most common EIM.
