| Juvenile Polyps |  |
| Peutz-Jeghers Syndrome, hamartomatous polyp of the small bowel pretty normal gland, just malformed, are not dysplastic |  |
| Small Intestinal PJ Hamartomatous Polyp small bowel, looks almost like normal mucosa, just disorganized |  |
| Colonic PJ Hamartomatous Polyp |  |
| Mucosal "freckles" in PJ syndrome |  |
| Colonic Hyperplastic polyp no malignant potential small happens anywhere in the colon serrated architecture of the glands, smooth out at bottom of the crypt cross-section looks kind of like a star |  |
| Sessile Serrated Adenoma usually right colon usually >1 cm dilated crypts |  |
| Tubular adenoma |  |
| Tubular Adenoma (TA) looks like low grade dysplasia in ulcerative colitis - stratification of nuclei - bluer than normal - darker than normal - regular-shaped glands - not complex back-to-back glands as seen in high-grade dysplasia |  |
