PS01.109: A RARE TUMOR OF THE CERVICAL ESOPHAGUS: SCHWANNOMA

Abstract

Abstract Background Schwannomas esophagus is very rarely seen. In this study, a schwannoma case with cervical esophagus was presented. Methods A 26-year-old female presented with dysphagia. In esophageal ultrasonography, a homogeneous, hypoechoic, and smooth-sided lesion originating from the proximal esophagus muscularis propria was detected. MRI revealed a well-defined mass lesion located in the cervical esophagus. Results The left cervical incision was performed and the lesion was enucleated. After the enucleation, saline was inserted into the enucleated area, and air was injected into the nasogastric tube to investigate the possibility of mucosal injuries. The esophageal muscle layers were then primarily closed with absorbable sutures. Frozen section examination was benign. Postoperative histopathological evaluation was assessed as accordance with schwannoma (Figure). Oral diet was started on the 3th postoperative day. There were no complications postoperatively. The patient was discharged on the 5th postoperative day. Conclusion The vast majority of esophageal tumors are cancer. Benign esophagial tumors constitute less than 1% of all esophageal tumors. Approximately 80% of benign esophagus tumors are leiomyomas. Esophageal schwannoma is very rare and difficult to diagnose by endoscopy and imaging methods. In these cases, surgery provides both definitive diagnosis and treatment. Disclosure All authors have declared no conflicts of interest.
