Schwannoma of the esophagus: A case report.

Esophageal schwannoma is a rare tumor among the thoracic diseases. The current study reports the case of a 62-year-old who presented with a 1-month history of dysphasia. A computed tomography scan of the chest revealed a solid mediastinal mass with a maximum diameter of 8 cm, with inhomogeneous enhancement following injection of contrast. The mass was compressing the trachea and esophagus. Subsequent to cisplatin plus fluorouracil infusion and embolization with a gelatin sponge, a standard right-sided posterolateral surgical procedure was performed in the right thorax, with tumor enucleation and mucosal repair. The diagnosis of esophageal schwannoma was confirmed by pathological examination. Microscopic examination revealed spindle cells, with the positive expression of S-100 protein and negative expression results for endothelial membrane antigen and desmin, confirming the diagnosis of esophageal schwannoma.
