Is called the transformation
zone(ectropion)
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
cases Adenocarcinoma --> 15 – 20%
Most occur at the SCJ
Melanoma and sarcoma occur rarely
Invasive CancerPatterns of spread
