Gastrointestinal (GI) schwannomas are very rare. Among GI schwannoma, the most common site is the stomach. Very few cases of intestinal schwannoma have been reported in the literature. Moreover, intestinal schwannoma in the setting of inflammatory bowel disease has rarely been reported. We report a case of ileal schwannoma incidentally detected in a 52-year-old lady with long-lasting ulcerative colitis having intestinal obstruction. On laparotomy, the patient was found to have adhesive intestinal obstruction due to a previous abdominal hysterectomy. On careful inspection of the bowel loops, a 2cm ileal lesion on the mesenteric border was detected. Segmental ileal resection was performed. Histopathology revealed a mesenchymal tumor with immunohistochemical analysis suggestive of schwannoma (CD117-, CD34-, SMA-, and S100+). The patient had an uneventful recovery with no recurrence on follow-up.
胃肠道（GI）神经鞘瘤非常罕见。在胃肠道神经鞘瘤中，最常见的部位是胃。文献中报道的肠道神经鞘瘤病例极少。此外，炎症性肠病背景下的肠道神经鞘瘤鲜有报道。我们报告一例52岁患有长期溃疡性结肠炎并伴有肠梗阻的女性患者偶然发现的回肠神经鞘瘤病例。剖腹手术时，发现患者因既往腹部子宫切除术导致粘连性肠梗阻。在仔细检查肠袢时，在肠系膜缘发现一个2cm的回肠病变。进行了节段性回肠切除术。组织病理学显示为间叶性肿瘤，免疫组化分析提示为神经鞘瘤（CD117阴性、CD34阴性、平滑肌肌动蛋白阴性和S100阳性）。患者恢复顺利，随访无复发。
