[Study on the localization of human papillomavirus DNA in the vulvar disease by means of in situ hybridization].
We investigated human papillomavirus (HPV) DNA of vulvar diseases obtained from 18 cases of condyloma acuminatum, 3 cases of hyperplastic dystrophy without atypia, 4 cases of lichen sclerosus, 4 cases of Bowenoid papulosis, one case of Bowen disease and 8 cases of squamous cell cancer by in situ hybridization with biotinylated HPV 6, 11, 16 and 18 DNA probes. The results of in situ hybridization analysis showed that HPV 6/11 was positive in 94.4% (17/18) of condyloma acuminatum. In 17 cases of HPV 6/11 positive condyloma acuminatum, 3 cases were positive for HPV 16 and one for HPV 18, respectively. HPV 16 was positive in 75.0% (3/4) of Bowenoid papulosis and one case of Bowen disease was positive for HPV 18. In two cases of Bowenoid papulosis which were positive for HPV 16, cervical carcinoma in situ containing HPV 16 DNA sequences was also found during the follow up period. In 8 cases of squamous cell cancer, 2 cases were positive for HPV 18, one for HPV 16 and one for HPV 6/11. All cases of hyperplastic dystrophy without atypia and lichen sclerosus were negative for HPV DNA. Our results suggested HPV is closely associated with vulvar neoplasia.
