Dysplasia is mainly seen as nuclei with hyperchromasia, coarse chromatin and irregular contours.[1]

Cervical intraepithelial neoplasia edit
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

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
