Cervical Intraepithelial Metaplasia

3 grades --> depending on the degree of cytological atypia thickness of the epi involved

Cervical Intraepithelial Metaplasia (CIN)

Screening and Cytology

Pap smear Conventional smear Liquid Based smear

Colposcopy

Treatment of CIN

Observation mild dysplasia (CIN I) may regress

spontaneously

Active treatment higher grades CIN II / CIN III

Invasive CancerPathological features2 main types Squamous cell carcinoma --> most
