title: Postmenopausal squamous-cell atypias: a diagnostic challenge.
abstract: Exfoliative cytologic studies directed toward atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL) have been neglected in the rising postmenopausal population. This retrospective study from 60 cases, initially interpreted as ASCUS or LSIL, concentrates on these lesions and their associated diagnostic pitfalls. Cytologic reevaluation of the 60 patients revealed squamous-cell abnormalities in 45 (18 ASCUS and 27 LSIL) and cervicitis alone in 15 cases. Follow-up studies of the 18 ASCUS cases showed cervicitis in seven, persistent ASCUS in five, CIN I in five, and VAIN I-II in one. Follow-up of the 27 cases categorized as LSIL, showed ASCUS in two, CIN in 20 and VAIN in one, while four had cervicitis alone. Interestingly, two of these 45 patients had only vaginal dysplasia. By application of uniform diagnostic criteria, 15 of the 60 cases were reviewed as benign. Pitfalls included inflammatory and drying alterations, reactive metaplasia, and sampling problems. Thus, squamous-cell abnormalities in postmenopausal women can be significant when artifactual alterations are eliminated.
