Benign esophageal schwannoma: report of a case.

Abstract

We report herein the case of an otherwise asymptomatic 62-year-old woman who was found to have an incidental esophageal lesion during endoscopic follow-up of an unrelated disorder. An esophageal submucosal tumor was diagnosed, and the patient was subsequently monitored on a regular yearly basis. As the diameter of the tumor doubled over a 4-year period, the possibility of a malignant lesion could not be excluded, and she was admitted to our hospital for further investigations. Esophagography, endoscopy, endoscopic ultrasonography, and computed tomography confirmed a submucosal tumor, 35 mm in length, in the thoracic midesophagus. A leiomyoma or leiomyosarcoma was suspected based on the known incidence of such tumors, and tumor enucleation was performed. Gross inspection revealed a solid tumor arising from the wall of the esophagus. Histopathologic examination showed intertwined bundles of spindle cells with spiral-like proliferation, and immunohistochemical studies were positive for S-100 protein, whereby a diagnosis of esophageal schwannoma was established. The patient experienced no postoperative complications, and her clinical course to date has been satisfactory. To date, 2 years 8 months after surgery, she has shown no sign of tumor recurrence and remains in good health.
