Fig. 1Endoscopic findings. (A) It shows about 45 mm-sized poypoid lesion with a short stalk at the base of the antrum. (B) Hemorrhagic ulceration with easy touch bleeding was noted at the proximal side of the lesion and thin, translucent mucosal surface with one exposed vessel was noted at the distal side of the lesion.
Fig. 2Abdominal computed tomography shows about 3.5×5 cm-sized polypoid mass with marginal enhancement, central inhomogeneous low density, and partial mucosal wall disruption at the anterior wall, lesser curvature of antrum, near the gastric angle (arrows).
Fig. 3Pathologic findings. (A) Surgical specimen reveals irregular blood vessels with loose connective tissues, chronic inflammatory cells and adipocytes (H&E stain, ×100). (B) Overlying gastric mucosa was nearly disappeared, the surface was replaced by submucosal tissue, and the reactive hyperplastic surrounding gastric mucosa was contiguous to the submucosal lesion (arrows) (H&E stain, ×50).
