[Argyrophilic nucleoproteins of the cervical epithelium in HPV infection and intraepithelial neoplasia].
50 colposcopic biopsies of cervical epithelium were studied, using a silver colloid technique. These comprised 28 cases of human papillomavirus infection of the cervix, 8 cases of cervical intraepithelial neoplasia (CIN) I, 8 cases of CIN II, 6 cases of CIN III. The AgNOR mean number of the basal and parabasal cells of the cervical epithelium was significantly different in virus infected cells and in CIN. Different patterns of AgNOR distribution were observed: they were single and compact in virus infection without dysplasia whereas they appeared small and often loosely arranged in dysplastic lesions. Our data suggest that this simple technique is diagnostically useful in the evaluation of borderline lesions.
