Histology Grade	Corresponding Cytology	Description	Image
CIN 1 (Grade I)	Low-grade squamous intraepithelial lesion (LSIL)	Mild epithelial dysplasia Confined to the basal 1/3 of the epithelium	File:LSIL (CIN 1), Cervical Biopsy (3776284166).jpg
CIN 2/3	High-grade squamous intraepithelial lesion (HSIL)^{[notes 1]}	Represents a mix of low and high-grade lesions not easily differentiated by histology
CIN 2 (Grade II)^{[notes 2]}		Moderate dysplasia confined to the basal 2/3 of the epithelium
CIN 3 (Grade III)^{[notes 3]}		Severe dysplasia with undifferentiated neoplastic cells that span more than 2/3 of the epithelium May involve the full thickness May also be referred to as cervical carcinoma in situ	File:Histopathology of CIN 3.jpg
