Documentation of colposcopic findings


The colposcopic findings should be documented using the nomenclature of the International Federation of Cervical Pathology and Colposcopy (2011 IFCPC nomenclature):

A diagrammatic representation of the colposcopic findings should be made, as shown below:

  • Draw two concentric circles.
  • The outer circle represents the boundary of the cervix, and the inner circle represents the external os.
  • The circle is divided into four quadrants by two perpendicular lines.
  • Draw the lesion, showing its position in relation to the quadrants and the external os.
  • The following legends are used as applicable: AW, acetowhite; P, punctation; M, mosaic; AV, abnormal vessels; I, iodine-negative.
  • The site of biopsy is marked by an x.

The Swede score should be calculated based on the following five characteristics:

Swede score (minimum, 0; maximum, 10):
  • Total score 04: normal/CIN1
  • Total score 56: CIN2/CIN3
  • Total score 710: CIN3/cancer.

Finally, a provisional diagnosis should be made from any of the following categories:
  • normal
  • condyloma/subclinical papillomavirus infection (SPI)
  • low-grade squamous intraepithelial lesion (LSIL)
  • high-grade squamous intraepithelial lesion (HSIL)
  • adenocarcinoma in situ
  • squamous cell cancer
  • adenocarcinoma
  • other.
The details of how to diagnose these individual conditions are discussed in subsequent sections.
