Whole of the transformation zone needs to be visualised, as this area is believed to be the site of neoplastic change. Colposcopy is deemed unsatisfactory if the whole of the transformation zone is not visualised. This situation may arise in postmenopausal women, and the clinician may reso to a sho course of oral oestrogens; and when colposcopy is repeated 6 -- 8 weeks later, the squamocolumnar junction will often be visible. Unsatisfactory colposcopy in the presence of abnormal cytology is an indication for a cone biopsy.
