Grade | Status | Findings |
0 | Normal | Epithelial cells small and round, nucleus/cytoplasm (N/C) ratio around 1/2. Goblet cells numerous, ovaloid with PAS (+) cytoplasm. |
1 | Slightly abnormal | Epithelial cells slightly larger and polygonal, N/C ratio 1/3. Goblet cells lower in number but well formed, ovaloid, and with PAS (+) cytoplasm. |
2 | Abnormal | Epithelial cells larger and polygonal, N/C ratio between 1/4 and 1/5. Goblet cells significantly lower in number, weaker and with PAS (+) cytoplasm. |
3 | Significantly abnormal | Epithelial cells larger and polygonal, their nuclei are small, pycnotic, N/C ratio 1/6, absence of goblet cells. |
PAS, periodic acid Schiff.
