Small-bowel tumors, both benign and malignant, are rare lesions that clinicians often do not encounter, accounting for less than 2% of gastrointestinal malignancies. Usually, benign small-bowel tumors, including polyps, are asymptomatic. The diagnosis of small-bowel tumors is difficult because of an often-delayed presentation and nonspecific signs and symptoms. We report an incidentally detected case of a long, pedunculated, large polyp of the terminal ileum, which protruded through the ileocecal valve into the cecum that was removed by colonoscopy in a 41-year-old male with intermittent right-sided lower-abdominal pain. The polyp was resected through snare polypectomy without complications. The histopathology of the resected polyp was confirmed as an ileal hyperplastic polyp. Two years later, there was no recurrence observed via postpolypectomy surveillance colonoscopy.
小肠肿瘤，无论良性还是恶性，都是临床医生很少遇到的罕见病变，占胃肠道恶性肿瘤的比例不到2%。通常，包括息肉在内的良性小肠肿瘤是无症状的。由于发病往往延迟且体征和症状不具特异性，小肠肿瘤的诊断很困难。我们报告一例偶然发现的病例，一名41岁男性，间歇性右下腹痛，经结肠镜检查发现回肠末端有一个长蒂的大息肉，该息肉经回盲瓣突入盲肠，并被切除。息肉通过圈套息肉切除术切除，无并发症。切除息肉的组织病理学确诊为回肠增生性息肉。两年后，息肉切除术后的结肠镜复查未发现复发。
