Abstract
A total of 268 biopsies from the genital region was screened for the presence of human papillomavirus DNA. The specimens included carcinoma of the vulva, vagina, cervix, corpus uteri, ovaries and penis, and Bowen's carcinomas, Bowenoid papuloses, Bowen's disease, cervical intraepithelial neoplasias (CIN I to III), Buschke-Löwenstein tumors, a cervical polyp, decidua, endometrium and histologically normal biopsies. Of 45 carcinomas, 18 contained either HPV 16 and/or 18 and 3 HPV 6-related sequences. In a few individual biopsies double or even triple infections were noted. Unusual was the presence of HPV 2-related DNA in one biopsy from Bowen's disease, whereas 2 condylomata acuminata contained HPV 3-related DNA and one contained HPV DNA related to a group of epidermal HPV's found in epidermodysplasia verruciformis lesions.
