title: [The new colposcopic signs--ridge sign and inner border].
abstract: OBJECTIVE
  To conclude knowledge about new colposcopic signs--ridge sign and inner border.
  
  
  METHODS
  Review article.
  
  
  METHODS
  Oncogynecological center, Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Medical School of Charles University, Prague.
  
  
  RESULTS
  Recently updated colposcopic classification includes two new colposcopic signs--ridge sign and inner border. Both are mainly present in lesions associated with oncogenic human papillomaviruses infection. Ridge sign represents thick opaque acetowhite epithelium irregularly growing in the squamocolumnar junction as ledges. Inner border is a sharp acetowhite demarcation within a less opaque acetowhite area. The sensitivity and specificity for detection of underlying high-grade lesion is 33.1% and 93.1% in ridge sign and 20% and 97% in inner border sign respectively.
  
  
  CONCLUSIONS
  Ridge sign and inner border are new colposcopic signs, which improve sensitivity and specificity of colposcopic examination.
