Abstract

Rationale:Gastric hyperplastic polyps are frequently found on upper gastrointestinal endoscopy and usually asymptomatic.Patients concerns:A 65-year-old man visited the emergency department due to melena. Emergency upper endoscopy revealed a semi-pedunculated polyp measuring 1.2 cm in diameter with blood oozing. We resected the polyp using snare polypectomy. Ulceration was noted on the polypectomy specimen and was thought to be a bleeding focus.Diagnoses:Histopathologic findings revealed hyperplastic polyp with focal well-differentiated adenocarcinoma in the ulcerated area and involvement of the lateral resection margin by carcinoma.Intervention:We performed additional endoscopic resection using endoscopic submucosal dissection at the previous polypectomy site.Outcome:At 1 year follow up, no recurrence or other distant metastasis was detected.Lessons:This is a rare case of upper gastrointestinal bleeding from a small gastric hyperplastic polyp, which was found to be adenocarcinoma. When bleeding small gastric polyps are encountered during endoscopy, the possibility of malignancy and wider resection should be considered.
