Schwannoma is a tumor formed of spindle cells that arise from the nerve plexus Schwann sheath cells of the gastrointestinal tract wall. It appears to be rare among the tumors of the gastrointestinal tract (GIT) and occurs mainly in the stomach, representing only 0.2% of all cancers of the stomach. It is usually a benign and slow growing tumor, and malignant transformation is very rare. For a long time it may remain clinically silent. Endoscopy of the upper gastrointestinal tract is considered to be the basic diagnostic tool. At this stage, the differential diagnosis is very difficult, based mainly on the exclusion of the presence of GIST (gastrointestinal stromal tumors), which appear more commonly in this location.
This study presents the case of a 44-year-old man with non-specific epigastric pain whose gastroscopy revealed a sub mucosal polyp of the body of stomach which was subsequently removed by endoscopic polypectomy. Based on histopathological and immunohistochemical findings, an Schwannoma Antoni type A was diagnosed.
