Colposcopic Terminology
5 Colposcopic Terminology
The latest version of the international terminology, which is used in this book, was formulated by the International Federation of Cervical Pathology and Colposcopy (IFCPC) with the International Society for the Study of Vulvar Disease (ISSVD) in Rio de Janeiro, Brazil, in 2011. This current version provides a comprehensive terminology for the entire lower genital tract and thus includes vulvar, vaginal, and anal disease as well as cervical findings. It also specifies terminology for different excision techniques and excision specimen dimensions (Tables 5.1–5.5).
