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.
