title: Colposcopy is superior to cytology for the detection of early genital human papillomavirus infection.
abstract: Of 2232 women with no cytologic evidence of intraepithelial neoplasia, 250 (11.2%) were positive for human papillomavirus deoxyribonucleic acid (DNA) by filter in situ hybridization. In 150 of those human papillomavirus-positive patients, an adequate colposcopic examination of the cervix was possible; human papillomavirus infection was diagnosed in 104 women (70%). Cervical cytology showed evidence of human papillomavirus infection in only 23 patients (15%). The following colposcopic features were most common: acetowhite epithelium (29%), punctuation (18%), acetowhite spikes (17%), and mosaicism (9%). Colposcopy was essentially normal in 27%. In 64 hysterectomized patients, vaginal colposcopy showed evidence of human papillomavirus infection in 38 women (59%). Vaginal cytology showed signs of human papillomavirus infection in only 9% (N = 6). Acetowhite spikes were seen in 52%, acetowhite epithelium in 5%, punctuation in 3%, and normal findings in 40%. Histologic examination of 25 biopsy specimens (cervical, N = 15; vaginal, N = 10) showed mainly a lack of glycogenation, acanthosis, and elongation of rete pegs. Koilocytosis and dyskeratosis were seen only in a few cases as rare foci, hence the negative cytology. We conclude that colposcopy is far more sensitive than cytology for the detection of cervical and vaginal human papillomavirus infection.
