A 78-year-old woman presented with an abdominal mass diagnosed by ultrasound and computed tomography. The patient underwent a laparotomy, during which a retroperitoneal tumor adherent to the cecum wall was identified. Microscopically, it showed spindle-cell proliferation in whorls, with low mitotic count (2 per 50 high-power fields) and was strongly positive for S-100 protein and vimentin. The final diagnosis was benign schwannoma of the cecum and no further treatment was required. Large intestine schwannomas are extremely rare tumors and only a few cases of schwannoma of the cecum have been reported to date.
一名78岁女性因超声和计算机断层扫描诊断出腹部肿块。患者接受了剖腹手术，术中发现一个附着于盲肠壁的腹膜后肿瘤。显微镜下，肿瘤呈漩涡状梭形细胞增生，有丝分裂计数低（每50个高倍视野2个），S-100蛋白和波形蛋白呈强阳性。最终诊断为盲肠良性神经鞘瘤，无需进一步治疗。大肠神经鞘瘤是极其罕见的肿瘤，迄今为止仅报道了少数几例盲肠神经鞘瘤病例。
