食道神經鞘瘤為一相當罕見之食道良性腫瘤。此種好發於女性之食道腫瘤在術前檢查中很難與其它發生於食道黏膜下之良性腫瘤區別。正確之診斷建立於術後病理標本玻片檢驗與特殊之螢光免疫染色。在施以完全切除手術後,其癒後相當良好。在此我們報告一個以外科手術成功切除食道神經鞘瘤之病例並回顧歷年來有關此種病例的文獻。
This is a rare case report of a 34-year-old woman with a schwannoma of the esophagus. The patient was referred to our hospital with a 6-month history of dysphagia. The evaluation revealed a submucosal tumor of the esophagus, which was successfully resected through a right thoracotomy. During the pathologic examination, the tumor was disclosed in the muscular layers of the esophagus; there was no anatomic relationship between the tumor and the vagus nerve. Negative immunohistochemical staining for CD34 and CD117 proved the tumor had not originated in the smooth muscle cells. From the histological characteristics and positive immunohistochemical staining for S-100 protein, the diagnosis of esophageal schwannoma was made.
