HSIL, high-grade squamous intraepithelial lesion; LSIL, low-grade squamous intraepithelial lesion. Lectin binding was evaluated as follows: 0, absent; 1, very low intensity; 2, low intensity; 3, medium intensity and 4, high intensity. The reaction intensity was evaluated in the different layers of the epithelium (Basal, Intermediate and Superficial).
