Unusual Presentation of Crohn’s Disease

Crohn’s disease is an inflammatory chronic disease affecting the gastrointestinal tract, mostly the colon and terminal ileum. The most frequent presentation is a young patient presented to a tertiary care center in Riyadh, Saudi Arabia in 2021 with chronic diarrhea, rectal bleeding, and abdominal pain. It is unusual for patients with Crohn’s disease to develop a benign large colon mass. In this case report, a female patient presented with chronic abdominal pain. The computed tomography findings showed a transverse colon mass invading the stomach. The biopsy report indicated reactive colonic mucosa with focal inflammatory exudate. She underwent a laparoscopic extended left hemicolectomy with en-bloc resection of the greater curvature of the stomach and primary anastomosis.
