Abstract
Gastric schwannomas (GS) are rare tumours originating from Schwann cells that affect the gastrointestinal tract, posing a diagnostic challenge due to their nonspecific symptoms. We report the case of a 61-year-old female presented with gastric fullness and occasional episodes of abdominal pain. Computed tomography revealed a solid mass in the lesser curvature of the stomach, initially suspected to be a gastrointestinal stromal tumours. During surgery, an exophytic lesion was identified and confirmed histopathologically and immunohistochemically as a gastric schwannoma. GS should be considered in the differential diagnosis of gastric subepithelial tumours. Its diagnosis relies on immunohistochemistry, and surgical resection ensures effective treatment.
