Abstract
- Schwannoma is a peripheral nerve sheath tumor first reported by Verocay in 1910. Most schwannomas are found in the spinal cord and large nerves of the neck and limbs. They rarely occur in the digestive tract. Gastric schwannomas comprise approximately 0.2% of all gastric tumors and 4% of benign gastric tumors. Usually, diagnosis is difficult without histopathologic evaluation because their clinical symptoms and endoscopic findings are not specific. Immunocytochemical studies are required to distinguish schwannomas from gastrointestinal stromal tumors (GISTs) and leiomyomas. This is a report of one case of gastric schwannoma presenting with iron deficiency anemia, a gastric submucosal tumor on endoscopy, and is diagnosed by immunohistochemical evaluation after subtotal gastrectomy.
