Intestinal duplication is a rare congenital anomaly. Development of adenocarcinoma on the basis of duplication is an even more rare condition. In our case, there was an adenocarcinoma arising from ileal duplication in a 28-year-old adult male patient. Following resection of the cystic masses with primary repair of the ileum during laparotomy, the patient was discharged from the hospital on the fourth postoperative day without any complication.
