Nomenclature CIN I CIN II CIN III Mild Dysplasia Moderate Dysplasia Severe Dysplasia Carcinoma in situ
Hinselmann,, 1925
Squamous Epithelium Columnar epithelium basal layer SCJ squamous epithelium Stratification
Squamous Epithelium stratified, nonkeratinizing epithelium original squamous epithelium
Cytological features The standard method for staining cytological preparations is that of Papanicolaou squamous epithelium
Squamous Epithelium parabasal cells superficial cells
Columnar Epithelium Columnar Epithelium Columnar epithelium
Columnar epithelium Normal columnar epithelium is easily recognised by its characteristic grape-like or villous appearance. Following application of acetic acid, the villi often appear white and are more easily recognizable. Columnar Epithelium

Transformation Zone Original SCJ
Immature metaplasia
Mature metaplasia The new epithelium results from transformation of columnar to squamous epithelium, through the process of squamous metaplasia Normal transformation zone

Nomenclature The concept of cervical intraepithelial neoplasia proposes that all degrees of abnormality should be given the same name, as part of a continuous spectrum of disease CIN I CIN II CIN III Mild Dysplasia Moderate Dysplasia Severe Dysplasia Carcinoma in situ
