- Mosaicism and punctuation
- Raised or ulcerated surface
Management of CIN
- LLETZ with local anaesthetic
- Needle excision of transformation zone
- Cone biopsy
- Follow up with a smear test and HPV screen in 6 months as proof of cure - if this is negative they can return to routine screening, if it is positive they should have a repeat colposcopy
