Enteritis cystica profunda (ECP) is characterized by mucin-filled cystic spaces that are partially lined by non-neoplastic columnar epithelium, and these are found in the wall of the small bowel. This is a very rare disease compared to cystica profunda involving the stomach or colon. The cause of ECP is still unclear. Most ECP is related to or it may accompany other intestinal diseases. We encountered one case of ECP of the duodenal bulb that presented as polyp, and this was not related to adenocarcinoma or any other intestinal diseases like Crohn's disease or ulcerative colitis. Endoscopic polypectomy was done and the ECP was later confirmed through histological evaluation.
