Table 3 Histological scores
Score | Epithelium | Dermis |
|---|---|---|
0 | No abnormalities | No leukocytes |
1 | One small ulcer / a few suspect areas with subepithelial infiltration of leukocytes | A few leukocytes, usually perivascular |
2 | A few ulcers, but predominantly epithelium without alterations | Some leukocytes, usually perivascular mononuclear cells |
3 | Some ulcers | Many leukocytes, countable |
4 | Frequent ulcers, intact epithelium between ulcers | Many leukocytes, uncountable due to overlapping or high-density masking cell edges |
5 | Many ulcers, no epithelium without alterations | Many leukocytes, uncountable tissue structure masked |
