CONFIRMATION OF THE PAPILLOMAVIRUS ETIOLOGY OF CONDYLOMATOUS CERVIX LESIONS BY THE PEROXIDASE-ANTIPEROXIDASE TECHNIQUE

Abstract

The peroxidase-antiperoxidase technique with the use of paraffin sections of 67 [human] cervical biopsy specimens and an antiserum cross-reactive with all papillomaviruses provided immunologic confirmation for the observation that papillomavirus infection of the cervix is not uncommon and that it most often presents as a flat, colposcopically unremarkable lesion. Papillomavirus antigen was detected in 21 of 35 condylomata of the cervix. Antigen-positive nuclei were found in the upper layers of the epithelium. EM examination of 5 reprocessed antigen-positive sections revealed, in each instance, papillomavirus particles in the nuclei of the most superficial layers of the condylomatous epithelium. The viral antigen was not detected in dysplasia, carcinoma in situ or invasive carcinoma.
