Human Papillomavirus Lesions in Association With Cervical Dysplasias and Neoplasias

Department of Pathology, University of Kuopio, POB 138, SF-70101 Kuopio 10, Finland.

Abstract

A series of 620 cervical biopsy specimens (precancerous and malignant) was assessed morphologically with special reference to the concomitant appearance of human papillomavirus lesions. Tissue samples from 346 of these biopsy specimens were stained for human papillomavirus antigens using the immunoperoxidase— peroxidase-anti-peroxidase (PAP) technique. Papillomavirus lesions were found in 55.6% of the biopsy specimens associated with all degrees of epithelial atypia. The mean age of the women with papillomavirus (condylomatous) changes was significantly lower (P < .0001) than that of women without these lesions, ie, those who had dysplasia/neoplasia without concomitant papillomavirus changes. Flat and inverted condylomas were most frequent between the ages 20 and 39 and were accompanied by more severe dysplasias than the papillomatous condylomas. In immunoperoxidase—PAP staining, 56% of the papillomavirus lesions were positive, the positivity being inversely related to the degree of epithelial atypia, and bearing some correlation with the condyloma type (papillary 100%, inverted 70%, and flat 52%). Although the results show a clear-cut association of human papillomavirus lesions with premalignant, and to a lesser extent with malignant squamous cell lesions of young sexually active women, thus suggesting a relationship between the virus and cancer, a careful follow-up study is needed to fully elucidate this relationship.
