Gastric schwannoma is a rarely seen gastric tumor accounting for only 0.2% of all gastric tumors. It is difficult to distinguish a gastric schwannoma from other gastric tumors preoperatively.Case presentation: A 30-year-old man with no significant medical history or physical examination findings presented with a 1-month history of right upper abdominal discomfort. The preoperative diagnosis was a gastrointestinal stromal tumor, but the postoperative pathologic and immunohistochemical examinations confirmed a gastric schwannoma. The patient underwent laparoscopic wedge resection of the stomach without additional postoperative treatment, and his postoperative recovery was uneventful. No recurrence or metastasis was found at the 2-year follow-up examination.
Although gastric schwannomas are usually not malignant, they are difficult to distinguish from other malignant stromal tumors preoperatively. Surgical resection should be recommended when a schwannoma is malignant or considered to be at risk of becoming malignant.
胃神经鞘瘤是一种罕见的胃肿瘤，仅占所有胃肿瘤的0.2%。术前很难将胃神经鞘瘤与其他胃肿瘤区分开来。
一名30岁男性，无明显病史及体格检查异常，出现右上腹不适1个月。术前诊断为胃肠道间质瘤，但术后病理及免疫组化检查确诊为胃神经鞘瘤。患者接受了腹腔镜胃楔形切除术，术后未进行其他治疗，术后恢复顺利。2年随访检查未发现复发或转移。
虽然胃神经鞘瘤通常不是恶性的，但术前很难与其他恶性间质瘤区分开来。当神经鞘瘤为恶性或被认为有恶变风险时，建议手术切除。
