Colposcopic patterns of vaginal intraepithelial neoplasia: a focus on low-grade lesions.

Abstract

OBJECTIVE The aim of this study was to evaluate the colposcopic patterns observed in women with a histopathological diagnosis of vaginal intraepithelial neoplasia, with a particular interest in analyzing the colposcopic characteristics of low-grade squamous intraepithelial lesions (LSIL). PATIENTS AND METHODS Medical charts and colposcopy records of women diagnosed with vaginal intraepithelial neoplasia from January 1995 to December 2015, were analyzed in a multicenter retrospective case series. The abnormal colposcopic patterns observed in women with vaginal LSIL and vaginal high-grade SIL (HSIL) were compared. The vascular patterns and micropapillary pattern were considered separately. RESULTS Regardless the histopathological grading, in women with vaginal SIL, the grade I abnormal colposcopic findings were more frequent than grade II abnormalities. However, a grade I colposcopy was more commonly observed in women with a biopsy diagnosis of LSIL rather than HSIL (p<0.0001). Similarly, the micropapillary pattern was more frequently observed in women with LSIL (p=0.004), while vascular patterns were observed more frequently in women diagnosed with vaginal HSIL (p<0.0001). In women with grade I colposcopy, the menopausal status and a previous hysterectomy appeared to be associated with the diagnosis of vaginal HSIL. CONCLUSIONS Grade I abnormal colposcopic findings were more commonly observed in women with vaginal LSIL, as well as the micropapillary pattern. On the other hand, grade II abnormal colposcopy and the presence of vascular patterns were more frequently observed in women with vaginal HSIL.
