[Detection of human papillomavirus in condyloma acuminata tissues]
1Department of Pathology, Cancer Centre, Sun Yat-sen University of Medical Sciences, Guangzhou.
Unlabelled:
We used immunohistochemical technique, in situ hybridization and polymerase chain reaction to detect HPV capsid antigen (HPV-Ag) and HPV-DNA sequences in genital condyloma and pseudocondyloma of vulvae tissues. We also observed the relation between HPV distribution in condylomas and their histological changes.
Results:
71.4% of condylomas were positive for HPV-Ag with IMHC, 96.5% of condylomas were positive for HPV6/11 DNA with ISH, and 100% of condylomas were positive for HPV6/11/16/18DNA with PCR. Only 21.4% of pseudocondylomas of vulvae were positive for HPV6/11/16/18DNA with PCR. By observing the distribution of labelled HPV-Ag and HPV-DNA, we found a close relation between HPV proliferative infection and the specific changes of condylomas.
