Pitfalls in Colposcopic Diagnosis
In 1981, The Royal College of Obstetricians and Gynaecologists, London, produced a document which stated ‘ideally no patient with cervical intraepithelial neoplasia (CIN) should be treated unless there has been prior colposcopic assessment.’ Anyone involved in the field of managing patients with abnormal cervical cytology must agree with this statement. Indeed, one can go further and say that colposcopy should always precede treatment! However, while basic colposcopy can be learned fairly easily there are certain changes which can make interpretation of the colposcopic picture extremely difficult. It would be easy if all acetowhite epithelium and all nonglycogenated epithelium was abnormal. This of course is not the case, and the aim of this presentation is to discuss some of the difficulties which may be faced by colposcopists.
