Peptic ulcer perforation, Hematoma, Submucosal tumor"/>
The gastric fundus is a rare site for benign ulcer and perforation to occur. A 47 year-old male presented to the emergency department with epigastric pain. An endoscopic examination revealed a submucosal tumor-like lesion with friable, superficial ulceration in the high body of the stomach. We performed surgical resection to rule out malignancy because of the lesion's large size and we found chronic gastric ulcer perforation, which was pathologically diagnosed. We presumed that the formation of the large hematoma, which mimicked a submucosal tumor, was a result of repeated bleeding, perforation and healing. We report here on a case of a large hematoma due to a benign gastric ulcer perforation in the fundus, and this all mimicked a submucosal tumor. (Korean J Gastrointest Endosc 2010;41:159-162)
