Abstract

Gastric schwannomas are rare benign tumors among the mesenchymal tumor of the gastrointestinal tract, arising from the nerve tissue which has a schwann cell sheath. These neoplasms are grossly similar to gastrointestinal stromal tumor (GIST), however, the clinical course of GIST is more aggressive compared to that of schwannomas. Synchronous occurrence of gastric epithelial and subepithelial tumors is rare. Besides, most subepithelial lesions are GIST. We present the case of a 57-year-old male with synchronous gastric schwannoma and gastric adenoma in the stomach. We found a gastric subepithelial lesion incidentally, the size of which was increasing and tubular adenoma was discovered in the covering mucosa during endoscopy follow-up. The synchronous lesion was removed by wedge resection, which was diagnosed as schwannoma with adenoma.
