| ===Microscopic===
| |
| Features:
| |
| *Increase in size & number of glands + irregular shape - '''key feature'''. | |
| *Cell stratification.
| |
| *Nuclear enlargement.
| |
| *Mitoses common.
| |
| *No nuclear atypia.
| |
| | |
| Notes:
| |
| *Normal "gland-to-stroma ratio" is 1:3.
| |
| *Two "touching" glands may be one gland in section.
