Human papilloma virus infection and associated intraepithelial neoplasia of the cervix, vagina and vulva.
A prospective colposcopic and histological study was performed on 333 patients with cytologically detected human papilloma virus infection (HPV) without cytological evidence of associated intraepithelial neoplasia. The colposcopic changes seen in the cervix, vagina and vulva were documented and target biopsies were taken from abnormal areas in these 3 sites. Colposcopic and histological evidence of HPV infection was found in the cervix of 314 patients (94%), vagina in 274 patients (82%) and vulva in 146 patients (44%). Histologically proven cervical intraepithelial neoplasia was found in 94 of 333 patients biopsied (28%), vaginal intraepithelial neoplasia in 3 of 333 patients biopsied (0.9%) and vulval intraepithelial neoplasia in 9 of 146 patients biopsied (6.2%). This study identified the colposcopic changes of HPV infection to be widespread throughout the lower female genital tract. The diagnosis of intraepithelial neoplasia undetected by cytology in 28% of patients with HPV infection indicates that such patients require colposcopy and target biopsy according to the colposcopic findings.
