Abstract
CORTES-VALENCIA, Tatiana et al. Giant esophageal schwannoma, a diagnosis by exclusion: Case report. Rev. colomb. Gastroenterol. [online]. 2021, vol.36, suppl.1, pp.37-41. Epub Feb 21, 2022. ISSN 0120-9957. https://doi.org/10.22516/25007440.516.
Introduction:
Esophageal schwannomas are tumors of the perineural components of the Schwann cell nerve sheath in peripheral nerves and account for 2% of primary esophageal tumors. Its low incidence makes diagnosis challenging; however, this etiology should be considered because its clinical and imaging behavior is rapidly progressive and unusual compared to other benign esophageal tumors.
Case study:
A 38-year-old female patient with a 1-year history of dysphagia underwent upper digestive tract endoscopy and contrast chest CT showing a mass at the cervical and transmural thoracic esophagus level, obstructing the lumen and exerting a mass effect on the trachea. A biopsy revealed a spindle cell tumor with positive immunohistochemistry for the S100 marker, leading to the diagnosis of esophageal Schwannoma. The patient is currently undergoing regular check-ups and is awaiting the advice of a clinical oncologist to recommend non-surgical treatment options due to the involvement of adjacent structures.
Conclusion:
The first diagnostic impression in the case of a suspected primary esophageal tumor would be a leiomyoma based on its incidence. The present case report of an esophageal schwannoma emphasizes that this is a differential diagnosis that requires timely treatment to avoid complications and sequelae in patients.
