Abstract：
Schwannomas of the gastrointestinal tract are rare spindle cell tumors that account for 2-6% of mesenchymal tumors. An elderly male was found to have a left colon mass on CT scan and colonoscopy with pathology of fibrotic tissue. A laparoscopic-assisted left hemi-colectomy with primary anastomosis was performed. Pathology demonstrated spindle cell neoplasm arranged in short fascicles that were strongly and diffusely positive for S100. An elderly female was found to have a submucosal lesion on surveillance colonoscopy in the proximal transverse colon. Biopsy with jumbo forceps revealed spindle cell neoplasm positive for S100. Patient underwent an uncomplicated limited non-oncologic segmental transverse colectomy. We report only the ninth case of left and sixth in the transverse colon described in the literature. As is true for other mesenchymal tumors, mucosal biopsy is usually inconclusive and deep biopsy or submucosal resection is required, making pre-operative surgical decision difficult.
摘要：
胃肠道神经鞘瘤是罕见的梭形细胞肿瘤，占间充质肿瘤的2-6％。在CT扫描和结肠镜检查中发现一名老年男性有左结肠肿块，并伴有纤维化组织病理。进行了腹腔镜辅助的左半结肠切除术和原发性吻合。病理显示梭形细胞肿瘤排列在短的束中，对S100呈强烈和弥漫性阳性。在近端横结肠的结肠镜检查中，发现一名老年女性有粘膜下病变。大型镊子活检显示梭形细胞肿瘤S100阳性。患者接受了简单的有限的非肿瘤节段性横结肠切除术。我们仅报道了文献中描述的横结肠中的第9例和第6例。正如其他间充质肿瘤一样，粘膜活检通常不确定，需要进行深层活检或粘膜下切除术，使术前手术决策困难。
