A case report of oesophageal schwannoma with thoracoscopic surgery

Abstract

Oesophageal schwannomas is a rare tumour and most commonly found incidentally or from diagnostic workup of dysphagia or dyspnoea. Most oesophageal schwannomas are benign and more frequently occurs in female than in the male. To date, <40 cases have been described in the English literature. In this study, we reported the case of a 57-year-old woman visited our hospital with the symptom of long-time dysphagia. A thoracic computed tomography demonstrated an upper oesophageal well marginated and homogeneous mass that adhered to the right wall of the oesophagus. Oesophageal endoscopy showed an extrinsic bulge 21 cm distal to the incisors with normal overlying mucosa. Strictly on a clinical and radiologic basis, this entity is impossible to definitively diagnose, the final diagnosis was based on histopathology and immunohistochemistry. Tumour cells stain positive for S100, a characteristic marker of Schwann cell. A minimally invasive thoracoscopic surgery was performed. The post-operative period was uneventful.
