Abstract
We report a case of a giant hyperplastic polyp of the stomach. A 74-year-old woman was diagnosed with a hyperplastic polyp of the stomach. She referred to our hospital because of rapid growth of the polyp. Gastrointestinal endoscopy revealed a giant polyp more than 10 cm in diameter.
Pathological examination of the polyp determined it was hyperplastic and the surrounding gastric mucosa also showed hyperplasia. Comorbid malignancy was suspected because of the size of the polyp, so we carried out a total gastrectomy to resect the giant polyp, including the surrounding mucosa. The pathological diagnosis was hyperplastic polyp and the size of the polyp was 11×8 cm, no comorbid of malignancy was seen. The carcinogenesis from a giant hyperplastic polyp is not uncommon. When a giant polyp is difficult to resect endoscopically, surgical resection should be considered.
