Abstract
The patient was a 47-year-old woman who was referred to our hospital with epigastric discomfort. The upper gastrointestinal endoscopy revealed flat elevation with central erosion at the lesser curvature of the supra angular region. In the 6 months follow-up of the lesion, it rapidly enlarged and formed nodular protrusion with redness. Pathological diagnosis of the biopsy specimen taken from the lesion was pyogenic granuloma. The endoscopic ultrasonography revealed that the lesion was localized in the mucosal layer. Therefore, the endoscopic resection was performed. Pyogenic granuloma is polypoid lesion consisting of capllary hemangioma, which occur preferentially in the skin and mucosa. It is a painless and is tended to hemorrhage. As to the gastrointestinal tract, it occurs relatively often in the oral mucosa and tongue. The occurence in the gastric mucosa has not yet been reported. Our case is supposed to be the first.
