title: Routine colposcopic survey of patients with squamous atypia. A method for identifying cases with false-negative smears.
abstract: Routine colposcopy was performed on 376 women with cervical squamous atypia (originally reported as "inflammatory atypia"). Colposcopy showed no abnormalities in 240 cases and a lesion in 136 cases; the latter were sampled by colposcopy-guided biopsy. The biopsy samples showed evidence of human papillomavirus (HPV) infection and/or grade I cervical intraepithelial neoplasia (CIN I) in 42 cases (11.1%), CIN II in 4 cases (1.1%) and CIN III in 5 cases (1.3%); the other 85 biopsied cases were histologically negative. Most cases of HPV/CIN I (35 of 42) and all of the cases of CIN II-III occurred in women under the age of 40. The detection rates were 4.4% for CIN II-III in women under the age of 40, 4.0% for HPV/CIN I in women 40 and older and 17.2% for HPV/CIN I in women under the age of 40 (P less than .001). It thus appears that women under the age of 40 who show cytologic evidence of squamous atypia would benefit from colposcopic examination.
