[Intraepithelial cervical squamous lesions: comparison between PAP-test, colposcopy, phase contrast microscopy and histology; usefulness of their synergic use].

Aim: In the last 10 years the tumors of cervix have showed a significant reduction in incidence, while the preneoplastic lesions are increased (linked often to human papilloma virus [HPV] infection), and so it is enhanced the role of early diagnosis.

Methods: The Authors have examined 124 patients at colposcopy showing transformation zone anomalies and/or HPV infections. The patients have submitted to PAP-test, phase contrast microscopy and to biopsy.
