Schwann cell tumors are benign tumors originating from Schwann cells of the peripheral nervous system and are extremely rare in the gastrointestinal system. They usually originate in the colon or rectum but can also occur in the esophagus and small intestine. Their occurrence is rare in GI tract and mainly in the sigmoid colon. Schwann cell tumors have no association with any familial cancer syndromes. We present a 65-year-old female patient who underwent routine colon cancer screening. In addition to open mouth diverticulosis, she was found to have a 3 mm polyp, which was diagnosed as a Schwann cell hamartoma after a biopsy. This study aimed to present this rarely reported case in the literature as an example of a tumor that should be included in the differential diagnosis when considering submucosal colonic lesions. Though the reported reoccurrence rate is low, this case highlights the lack of published guidelines regarding appropriate follow-up surveillance periods.
施万细胞瘤是起源于周围神经系统施万细胞的良性肿瘤，在胃肠道系统中极为罕见。它们通常起源于结肠或直肠，但也可发生于食管和小肠。其在胃肠道的发生率很低，主要发生在乙状结肠。施万细胞瘤与任何家族性癌症综合征均无关联。我们报告一例65岁女性患者，该患者接受了常规结肠癌筛查。除张口憩室病外，还发现一个3毫米的息肉，活检后诊断为施万细胞错构瘤。本研究旨在展示这一文献中鲜有报道的病例，作为在考虑结肠黏膜下病变时应纳入鉴别诊断的肿瘤实例。尽管报道的复发率较低，但该病例凸显了缺乏关于适当随访监测期的已发表指南的问题。
