We experienced a case of thoracoscopic enucleation in the prone position for schwannoma of the esophagus, which is an extremely rare procedure for a benign esophageal tumor. A 69-year-old female presented at our hospital in 2016 with a history of dysphagia that had been gradually worsening since 2014. Abdominal and chest enhanced computed tomography showed a tumor of approximately 30mm diameter at the dorsal aspect of the carina tracheae. We suspected that the primary tumor was located in the esophagus. Upper gastrointestinal endoscopy revealed a 30mm submucosal tumor in the middle thoracic esophagus. Cytodiagnosis using endo ultrasound-fine needle aspiration indicated a suspected non-epithelial tumor, but definitive diagnosis was not reached. We performed thoracoscopic enucleation in the prone position, as the patient requested surgical treatment. The tumor was diagnosed as a schwannoma based on the pathological examination of resected material. Herein, we report the details of our case and present a review of the exiting literature.
