Pedunculated gastritis cystica profunda polyp presenting with upper GI bleeding and volcano-like surface alteration

Abstract

A 69-year-old male patient presented with upper GI bleeding and positive shock criteria (hamoglobin 6.2 g/dL). After stabilization, acute endoscopy poorly informative due to abundant blood clots suggested a subepithelial lesion with ulcerated surface potentially a gastric GIST, and injection treatment was performed. Since the patient further stabilized in the next hours, a CT scan was performed describing rather a 50-mm intraluminal lesion. Second-look endoscopy the next morning indicated a pedunculated polyp lesion at the lesser curvature with diffuse surface ulceration (Fig. 1A).
