摘　　要：BACKGROUND Endoscopic submucosal dissection(ESD)is the treatment of choice for early gastric cancer and premalignant gastric dysplasia.In some cases,ESD induced ulcer heals as a polypoid nodular scar(PNS).These scars may make the physicians raise several clinical implications such as post-ESD neoplastic recurrence.CASE SUMMARY We described a case of gastric ESD induced PNS which is regressed after Helicobacter pylori(H.pylori)eradication.A 58-year-old male patient was referred to the outpatient clinic for evaluation and treatment of gastric low-grade dysplasia(LGD).ESD was performed.A PNS was developed at the ESD site.An endoscopic biopsy was done and there was no histological evidence of remnant tumor or recurrence but a hyperplastic mucosal change.The PNS showed increase in size in follow-up endoscopy,and the biopsy specimen demonstrated H.pylori infestation.H.pylori eradication was done and the PNS was regressed.CONCLUSION H.pylori eradication is considerable for the regression of PNS if H.pylori infesta tion is confirmed.
