Diagnostic Procedures for Lesions of the Cervix

  • Alex Ferenczy


In the United States for a number of years colposcopy8 and exfoliative cytology were regarded as competitive methods in the early detection of cervical neoplasia. In the last decade, however, colposcopy became accepted and used as a complementary technique to cytology.4 Cytology is a laboratory method of detection, based on the evaluation of the morphologic alterations of the exfoliated cells. Colposcopy is a clinical method designed for the early diagnosis of noninvasive, preclinical invasive, and frank invasive cervical cancers. Colposcopy evaluates the modifications in the surface vascular system of cervical epithelium, which occur in response to biochemical and metabolic alterations in neoplastic tissues. When colposcopy and cytology are combined their diagnostic accuracy is near 100%.1,8 The colpo-scope (Fig. 8.1) is a stereoscopic microscope with focused illumination that provides a three-dimensional image of tissue surfaces. It is particularly useful in the cervix, vagina, and vulva.
