ABSTRACT
Schwannoma is a benign, slow-growing neoplasm originating in any nerve that has a Schwann cell sheath. They rarely occur in the digestive tract, but when they do, the most common site is the stomach. And they represent 0.2% of all gastric tumors. Because gastric schwannomas are usually covered by intact mucosa and mainly involve the submucosal and muscularis propria, they are categorized as gastric subepithelial tumor(SET). Although endoscopic examination is important in the initial evaluation of a gastric SET, they cannot provide enough information in the differential diagnosis of a gastric SET. Transabdominal ultrasonogrphy provides useful information regarding the layer of origin, the size of the lesion, morphologic features and differential diagnosis and follow up of gastric SET. Author report a case of gastric schwannoma presenting as a gastric subepithelial tumor in a 65-year-old male patient.
