Colposcopic patterns of vaginal intraepithelial neoplasia: a study from the Italian Society of Colposcopy and Cervico-Vaginal Pathology

The aim of this study was to evaluate the colposcopic patterns observed in women with a histopathological diagnosis of vaginal intraepithelial neoplasia (VaIN). The medical charts and the colposcopy records of women diagnosed with VaIN from January 1995 to December 2013 were analysed in a multicentre retrospective case series. The abnormal colposcopic patterns observed in women with VaIN1, VaIN2 and VaIN3 were compared. The vascular patterns and micropapillary pattern were considered separately. A grade II abnormal colposcopic pattern was more commonly observed in women with a biopsy diagnosis of VaIN3 rather than with VaIN1 or VaIN2 (P
