Nucleolar organising regions in cervical intraepithelial neoplasia.

Nucleolar organising regions in cervical intraepithelial neoplasia.

The variations in the numbers of nucleolar organising regions (NORs) among different grades of cervical intraepithelial neoplasia (CIN) were investigated using a silver staining technique. Twenty four biopsy specimens were studied (six normal and six of each of the three grades of CIN) by staining paraffin wax sections using a silver (AgNOR) method that stains the NORS as multiple black dots wi...

A morphometric study of nucleolar organiser regions in cervical intraepithelial neoplasia.

The study sought a correlation between the number of AgNOR granules and the degree of cervical intraepithelial neoplasia (CIN). Thirty-five sections (5 normal, 10 CIN1, 10 CIN2 and 10 CIN3) were subjected to retrospective analysis. The percentage of cells with 1, 2, 3, 4 and more AgNORs was calculated and the number of granules per 100 cells was counted. The number of cells containing single gr...

Cervical intraepithelial neoplasia.

The theoretical and practical reasons for replacing the terms "cervical dysplasia" and "cervical carcinoma in situ" by the single diagnostic entity of "cervical intraepithelial neoplasia" are reviewed and the advantages and drawbacks of this newer terminology discussed. The histological characteristics and cytological features of the various grades of cervical intraepithelial neoplasia are desc...

Clinical analysis of cervical intraepithelial neoplasia with vaginal intraepithelial neoplasia

The purpose of this prospective cohort study is to evaluate the importance of screening and its diagnostic accuracy compared with the pathological diagnosis of cervical intraepithelial neoplasia (CIN) with vaginal intraepithelial neoplasia (VAIN).The prospective study enrolled 419 patients (pts) and was conducted between February 1, 2015 and January 31, 2016 at Beijing Obstetrics and Gynecology...
