Gastric schwannomas and gastrointestinal stromal tumors (GISTs) are two types of mesenchymal tumors, which represent a group of rare tumors of the gastrointestinal tract. The differential diagnosis between these two tumors is difficult given their very similar appearance and clinical features. The authors present a case of a 63-year-old man with melena and epigastric pain. An upper digestive endoscopy was performed, revealing an ulcerated gastric subepithelial lesion suspected to be a GIST. Further imaging with a computed tomography (CT) scan revealed a well-defined hypodense solid nodular mass, with homogeneous enhancement, measuring 22 × 18 mm, on the anterior wall of the transition between the body and gastric antrum, situated within the submucosal layer. The patient subsequently underwent a laparoscopic atypical gastrectomy, which proceeded without complications. The pathological examination of the excised lesion confirmed it to be a gastric schwannoma, with complete excision. This case report illustrates a rare cause of gastrointestinal bleeding, that requires immediate action, and en bloc resection is usually curative. Given the excellent prognosis after complete resection, a correct diagnosis is essential.
