Gastric glomus tumor presenting with massive upper GI bleeding: A challenging to diagnose and treat tumor

Glomus tumors are infrequent benign tumors that originate from the glomus body and can be found anywhere in the body including the gastrointestinal tract. It is rare that gastric glomus tumors present with life‐threatening upper GI bleeding. Diagnosis of gastric glomus tumors poses a challenge due to overlapping endoscopic and endosonographic features with other gastric subepithelial lesions, and the final diagnosis may not be clear until after surgical resection and pathological examination. We report the case of a 61‐year‐old patient who presented with massive upper GI bleeding secondary to an ulcerated gastric glomus tumor that was eventually treated with surgical wedge resection of the tumor.
