Regression of gastric endoscopic submucosal dissection induced polypoid nodular scar after Helicobacter pylori eradication: A case report

Figure 3 Endoscopic biopsy. A: Histologic finding of poypoid nodular scar, 3 mo after endoscopic submucosal dissection. Gastric hyperplastic polyp. This polyp shows tortuous distorted and dilatated glands, abundant lamina propria. There is no evidence of dysplasia (hematoxylin and eosin, ×100); B: Histologic finding of polypoid nodular scar, 1 year after endoscopic submucosal dissection. Helicobacter pylori were identified within foveolar epithelium (arrow) (hematoxylin and eosin, ×400).
