CAUSES OF NON-CORRELATION BETWEEN CYTOLOGY AND COLPOSCOPY
* Cervical lesion is in the endocervical canal, or not in the cervix.
* Colposcopic findings are not apparent to the examiner, although the lesion is present. (eg. Severe atrophy obscures the colposcopic findings).
*The biopsies performed did not include the visualized lesion.
*The laboratory did not identify the lesion within the submitted
biopsies. (Orientation of the biopsy, initial sections of the
paraffin embedded tissue did not include the lesion.)
*The cervical cytologic sample was classified as HSIL, but only
contained immature metaplastic, or atrophic squamous
cells (interpretative cytology issue).
