Abstract
We report two cases of esophageal schwannoma. A 66-year-old woman (case 1) and a 56-year-old man (case 2) were admitted for abnormal shadows pointed out in barium esophagography. In case 1, an esophageal submucosal tumor was resected by transthoracic esophagectomy with gastric tube reconstruction. In case 2, esophageal tumor was enucleated by thoracoscopic surgery. To remove the tumor from the muscular layer, a Sangstaken-Blakemore tube (S-B tube) was used intraoperatively inserted into the esophagus preoperatively. Both tumors consisted histopathologically of spindle-shaped cell bundles and S-100 protein expression was immunohistochemically confirmed in both tumors. The definitive diagnose was benign esophageal schwannoma in both cases. Esophageal schwannoma is extremely rare, and we review 26 cases from the Japanese literature.
