Which feature is more characteristic of Crohn's disease than ulcerative colitis?

• A. Perianal manifestations
• B. Continuous colon inflammation
• C. Mucosal friability
• D. Pseudopolyps

Answer: (A)

Crohn's disease typically involves the entire thickness of the bowel wall (transmural inflammation) and often affects the perianal region, leading to fistulas, fissures, and abscesses. This perianal disease is a hallmark that distinguishes Crohn's from ulcerative colitis, where inflammation is usually confined to the mucosa and submucosa of the colon and tends to be continuous from the rectum upward. While ulcerative colitis commonly shows mucosal friability and pseudopolyps, these features are less characteristic of Crohn's. Therefore, perianal manifestations are more indicative of Crohn's disease.
