Significance of anucleated squames in Papanicolaou-stained cervicovaginal smears.
The significance of anucleated squames in Papanicolaou-stained cervicovaginal smears as a marker of hyperkeratosis with an underlying significant atypia was evaluated. Over a two-year period, 785 (0.47%) of 168,215 cervicovaginal smears were signed out as demonstrating anucleated squames without any other abnormality. Cytologic or histologic follow-up specimens were available for 304 of those smears (42%). Histology or cytology showed condyloma or a more significant lesion in 13 cases (4.3%); histology showed hyperkeratosis without atypia in 25 cases (8.2%) and chronic cervicitis in 23 (7.5%); follow-up cytology demonstrated persistent anucleated squames in 47 cases (15.4%) and was negative in 196 (64.6%). During this same period, the rate of condyloma or a more significant lesion in all Papanicolaou smears examined was 1.69%. Thus, reporting the presence of anucleated squames in the absence of any other abnormality appears to be of marginal value as a screening procedure for predicting the existence of a significant lesion. Noting their presence in patients with a prior diagnosis of condyloma or dysplasia remains an important tool for detecting a persistent lesion. Lack of standardization among pathologists in the recognition of anucleated squames may partially explain the low predictive value of this finding: an informally conducted survey revealed a mean accuracy of 46% in the identification of true anucleated squames.
