In this report, we describe a rare case of vagus nerve schwannoma associated with esophageal cancer. A 70-year-old man visited our hospital complaining of worsening dysphagia. His upper gastrointenstinal endoscopy revealed a mass in the esophagus. A contrast-enhanced chest computed tomography also detected a 15 mm nodule attached to the tracheal membrane. This nodule was diagnosed as a metastatic lymph node. Although the primary tumor reduced after neoadjuvant chemotherapy, the nodule remained intact ; it showed fluorodeoxyglucose accumulation on positron emission tomography. We had a clinical diagnosis of stage III after neoadjuvant chemotherapy and underwent surgery. Intraoperatively, the nodule could not be detached from the right vagus nerve ; therefore, we excised the nodule along with the adjacent vagus nerve. The nodule was pathologically diagnosed as a vagus schwannoma. The nodule was not a regional lymph node metastasis of esophageal cancer. His postoperative course was uneventful, and he is currently undergoing outpatient follow-up without recurrence. J. Med. Invest. 68 : 205-208, February, 2021.
在本报告中，我们描述了一例罕见的与食管癌相关的迷走神经鞘瘤。一名 70 岁男性因吞咽困难加重就诊于我院。上消化道内镜检查显示食管内有一肿块。胸部增强 CT 还发现一个 15 毫米的结节附着在气管膜上。该结节被诊断为转移性淋巴结。尽管新辅助化疗后原发肿瘤缩小，但结节仍然完整；它在正电子发射断层扫描上显示氟脱氧葡萄糖积聚。新辅助化疗后我们临床诊断为 III 期，并进行了手术。术中，结节无法从右迷走神经上分离；因此，我们切除了结节和相邻的迷走神经。结节病理诊断为迷走神经鞘瘤。结节不是食管癌的区域淋巴结转移。他的术后过程顺利，目前正在门诊随访，无复发。J.
