Gastric Schwannoma
Resected gastric mass after surgery.
  • Submucosal tumours include a range of lesions, including benign and malignant lesions.
  • Schwannoma is a type of submucosal tumour that is generally asymptomatic, benign and slow-growing.
  • However, unlike this case, the tumour more frequently appears in the head and neck region.

This article describes the case of a 28-year-old female patient diagnosed with gastric schwannoma. The patient presented to the emergency department with symptoms of abdominal pain, recurrent vomiting and hematemesis. Moreover, she complained of a several weeks history of abdominal pain with severe anorexia and recurrent vomiting.

On examination there were no signs of systemic or local complications. Physical examination was unremarkable, too. Doctors advised a diagnostic endoscopy after admission which showed an antral submucosal mass, measuring 5 cm x 6 cm with central umbilication. Likewise a double contrast-enhanced abdominopelvic CT scan was also performed which showed a hypodense mass. The mass was seen along the anterior wall of the gastric antrum, in addition to luminal obstruction with gastric dilation in the body of the fundus and subsequent pyloric stenosis. The patient was referred for surgery, with suggestion of GIST.

Treatment included an open surgery for obstruction relief with subtotal gastrectomy with Roux-en-Y gastrojejunostomy. Histopathological findings were consistent with the diagnosis of gastric schwannoma. Wavy spindled cells separated by fibrotic bundles encompassed with tumoral capsule were observed. In addition, there were signs of lymphoid aggregation around the capsule. Histology and immunohistochemistry confirmed the diagnosis of astric submucosal schwannoma.
