Schwannomas of the cervical esophagus are extremely rare, as fewer than a dozen reports have been published in the literature. Therefore, their clinical characteristics and management have not been definitively elucidated. We report 2 cases of cervical esophageal schwannoma (CES) in which the patients-a 52-year-old woman and a 53-year-old woman-were initially misdiagnosed clinically. The correct diagnosis was later established on the basis of contrast-enhanced computed tomography (CT) and intraoperative frozen-section analysis. In both cases, the tumor was enucleated, and the esophagus was closed by primary intention. Both patients resumed an oral diet 2 weeks postoperatively. Follow-up detected no evidence of recurrence. Our review of the literature revealed that CES is a benign mesenchymal tumor that can be misdiagnosed both clinically and pathologically. Preoperative contrast-enhanced CT and intraoperative frozen-section analysis help in the planning for conservative enucleation, which precludes the need for esophageal resection and its associated morbidity.
颈段食管神经鞘瘤极为罕见，因为文献中发表的报道不足十二例。因此，其临床特征和治疗方法尚未得到明确阐明。我们报告2例颈段食管神经鞘瘤（CES）病例，患者分别为一名52岁女性和一名53岁女性，最初临床诊断有误。后来通过增强计算机断层扫描（CT）和术中冰冻切片分析得以确诊。两例患者均行肿瘤摘除术，食管一期缝合。两名患者术后2周均恢复经口进食。随访未发现复发迹象。我们对文献的回顾显示，CES是一种良性间叶组织肿瘤，在临床和病理上都可能被误诊。术前增强CT和术中冰冻切片分析有助于规划保守性摘除术，从而避免了食管切除术及其相关并发症。
