Rectal mucosal prolapse syndrome (RMPS) is a rare condition that mimics Crohn's disease (CD) in imaging and endoscopy. We present a 29-year-old male with rectal tenesmus and a mid-rectal mass initially diagnosed as CD based on colonoscopy and MRI. After failed corticosteroid therapy, endoscopic resection revealed fibromuscular obliteration pathognomonic for RMPS. Chronic prolapse may induce secondary inflammation mimicking CD (including ulceration, stricture, and pseudofistulation), necessitating careful differential diagnosis to avoid unwarranted corticosteroid therapy.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
