Which of the following would be the best morphological feature to distinguish ulcerative colitis from Crohn's disease? (AIIMS Nov 2013)



A Diffuse distribution of pseudopolyps

B Mucosal edema

C Crypt abscesses

D Lymphoid aggregates in the mucosa

Ans. A Diffuse distribution of pseudopolyps l

Pseudopolyps (inflammatory polyps) can be seen in both Crohn's disease and ulcerative colitis.

Even Mucosal edema, crypt abscess and mucosal lymphoid aggregates are features common to both the inflammatory bowel disease.

However, diffuse distribution of these polyps is observed only in ulcerative clitis because in Crohn’s disease. There is presence of skip lesion in which there is presence of normal area adjacent to diseased segments of the intestine. So, patchy distribution of polyps is observed in Crohn’s disease.
