Xanthogranulomatous gastritis (XGG) presenting as a subepithelial tumor (SET) is a very rare entity. We report a case of SET-like XGG diagnosed and treated with endoscopic resection. A 55-year-old female patient was initially referred with a 1.5-cm SET located at the anterior wall of the middle antrum. Endoscopic ultrasound examination revealed submucosal invasion without any perigastric lymph node enlargement. Endoscopic resection was performed for an accurate diagnosis and treatment, and the lesion was diagnosed histopathologically as XGG. At the 18-month follow-up after endoscopic resection, there was no evidence of XGG recurrence. SET-like XGG is very rare and the diagnosis is a preoperative challenge. However, inflammatory tumors should be considered in the differential diagnosis of SET
Key Words: Endoscopic resection; Subepithelial tumor; Xanthogranulomatous gastritis
