Comparison of 4 classification systems for squamous cells; Bethesda 2001 (cytology), cervical intraepitheliali neoplasia (CIN) nomenclature (histology), dysplasia nomenclature (cytology and histology), and Papanicolaou classification (cytology; the categories are not shown to scale). ASC-US indicates atypical squamous cells of undetermined significance; NILM, negative for intraepithelial lesion and malignancy; SIL, squamous intraepithelial lesion; LSIL, low-grade SIL; HSIL, high-grade SIL; CA, invasive carcinoma; ASC-H, atypical squamous cells, cannot exclude HSIL; NOS, not otherwise specified; KA, koilocytotic atypia; Mild, mild dysplasia; Mod, moderate dysplasia; Sev, severe dysplasia; CIS, carcinoma in situ.
