Age-Related Frequency of Viral Lesions and Their Association with Uterine Cervical Intraepithelial Neoplasia

Data collection forms of 50,165 routine smears were examined, and of these 47,577 were considered for this study. Viral cytological lesions (VL) were observed in 101 cases: of these, 19 were associated with cervical intraepithelial neoplasia. The total frequency of VL was 0.21%, with the peak in the teenager group (0.49%). The frequency of CIN among VL showed an overall frequency of 18.8 %: this was null under 21 years of age and highest (50 %) between 51 and 60 years of age. The frequency of VL in relation to clinical provenance of patients and the season of the year did not attain significance.
