| Nu dysplasia | Dysplasia |
| Proliferative epithelium restricted to base | Proliferative epithelium present at the surface |
| Gland lining cells mature at the surface | No surface maturation |
Non-proliferative crypt (left) versus proliferative dysplastic crypt (large at right, with crowded hyperchromatic nuclei).
In nuclear crowding, also look for inflammation: Here a hyperplastic polyp with inflammatory reactive changes, reminiscent of adenoma.
