[Histological aspects of lesions of the cervix uteri correlated with different types of human papillomavirus].
Cervical biopsies from 66 women presenting an abnormal smear, with HPV related features were studied and histologic features were correlated to the HPV type, as determined by molecular hybridisation studies. HPV DNA sequences were evidenced in 13 of 19 lesions corresponding to exophytic or flat condyloma (HPV type 16 in seven cases, HPV type 11 in four cases, as yet uncharacterized HPV types, HPV X, in two cases). Fourty biopsies were histologically interpreted as CIN, on the basis of atypical mitotic figures (AMF) and/or basal-parabasal cell atypia. HPV type 16 was evidenced in 20 cases (3 cases of double infection: HPV types 16 and 18, HPV types 16 and 33, HPV types 16 and X). In 10 other cases, HPV DNA sequences corresponding to HPV type 11 (one case), HPV 18 (one case) and HPV X (8 cases) were evidenced. In this study, potentially oncogenic HPV types (HPV 16, HPV 18, HPV 33) have been found only in CIN lesions defined on the presence of AMFs and/or basal-parabasal cells atypia. These histologic criteria seem to allow a distinction between low and high risk cervical lesions.
