We report a case of a hyperplastic polyp which underwent malignant transformation, during radiographic and endoscopic follow-up for 13 years. The patient was a 75-year-old woman who had a 10-mm sized pedunculated polyp in the gastric body. Histologic examination revealed that the lesion was a hyperplastic polyp. There was no significant change in size and shape over the next 12 years. However, the polyp inceased to 19mm in size and developed uneven lobulation in the most recent 12month peroid. Endoscopy revealed a pedunculated polyp with a localized erosion, and biopsy showed a Group V lesion. Polypectomy was performed and the diagnosis of hyperpastic polyp with malignant transformation was confirmed histologically.
