Unusual Presentation of Crohn's Disease: Distal transverse colon mass.

Crohn's disease is an inflammatory chronic disease affecting the gastrointestinal tract, mostly the colon and terminal ileum. A 42-year-old female patient presented to a tertiary care centre in Riyadh, Saudi Arabia, in 2021 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. The patient was subsequently diagnosed with Crohn's disease based on the final pathology report. The patient had an uncomplicated postoperative course and is being follow-up.
