| [ Summary ] | Common hyperplastic polyps (common HPs) are non-neoplastic lesions and are found most frequently in the sigmoid colon and the rectum. They have a distinctive morphology-typically they are mucosal nodules less than 5 mm in size, which are pale and sessile. On the other hand, while large (defined as greater than 10 mm) hyperplastic polyps (large HPs) are morphologically similar to common HPs, large HPs are predominantly located in the right-side of the colon, and are pathologically different from common HPs. Moreover, a certain percentage of large HPs are potentially malignant. Therefore, large HPs should be considered as lesions, should be resected endoscopically. | |
