Abstract

The atypical transformation zone is that area of the cervix whose limits define cervical intraepithelial neoplasia. On Colposcopy of transformation zone it is possible to classify the lesions seen as low grade CIN, high grade CIN, vaginal extension or occult invasive lesions. Glandular caners may be suspected on Colposcopy but diagnosis is based on histology. HPV testing using Hybride Capture 2 improves the accuracy of colposcopy in detection of cervical Intraepithelial Neoplasia Roche AMPLICOR HPV test is comparable to other HPV tests (HCII, PCR) in detecting CIN in colposcopy setting.
