Hyperplastic polyps: More than meets the eye? Report of sixteen cases

The vast majority of hyperplastic polyps are small, left-sided, and inconsequential in nature. However, hyperplastic polyps that are large, right-sided, mixed, and found in association with a family history of carcinoma may represent an atypical group, and their clinical significance is uncertain. We believe that these atypical lesions should not be lumped together with the common variety of diminutive hyperplastic polyps. Rather, when such hyperplastic polyps are encountered, they should be excised and the patient should be placed on regular colonoscopic surveillance.
