Overview
Historical Perspective

- In 1928, the first screening was developed by Aurel Babeș, a Romanian pathologist to diagnose cervical intraepithelial neoplasia.[1]
- In 1980, human papillomavirus (HPV) was first identified in the pathogenesis of cervical intraepithelial neoplasia.[2]
Classification
- Cervical intraepithelial neoplasia has 4 cytological classifications: Bethesda system, Papanicolaou classification, CIN nomenclature, and dysplasia nomenclature.
- Cervical intraepithelial neoplasia may be classified according to Papanicolau into 3 subtypes:
- CIN1 (Grade I)
- CIN2 (Grade II)
- CIN3 (Grade III)
- Cervical intraepithelial neoplasia may be classified according to Bethesda system into 3 subtypes:
- Low grade squamous intraepithelial lesion (LGSIL)
- High grade squamous intraepithelial lesions (HSIL)
- Carcinoma in situ
- Other variants of cervical intraepithelial neoplasia include [disease subtype 1], [disease subtype 2], and [disease subtype 3].
