Postmenopausal squamous atypia: a spectrum including "pseudo-koilocytosis".
In addition to typical atrophy, the postmenopausal cervix may exhibit a spectrum of epithelial and cellular alterations, including prominent perinuclear halos, nuclear hyperchromasia, variation in nuclear size, and multinucleation. It has not been determined whether such changes, termed postmenopausal squamous atypia (PSA), represent age-related epithelial disturbances or human papillomavirus (HPV)-related low-grade squamous intraepithelial lesions (condyloma). We surveyed 30 cervical biopsies from 26 women over the age of 50 that contained cytoplasmic halos and a spectrum of nuclear alterations, either alone or in association with atrophy. Twenty-three exhibited epithelium with 2- to 3-fold nuclear enlargement, and 18 had moderate or marked nuclear staining intensity. Eleven had a maximum of one or more multinucleated cells in a high-power field. Despite the nuclear alterations, none of the biopsies were positive for HPV by PCR analysis. This is in contrast to 104 of 141 low- and high-grade squamous intraepithelial lesions from a wide age range of women analyzed in the same manner (P = .000006). Features distinguishing PSA from HPV-associated low-grade squamous intraepithelial lesions (condyloma) included less variation in nuclear size and staining intensity, more finely and evenly distributed nuclear chromatin, and greater uniformity of perinuclear halos in PSA. In menopausal or postmenopausal women, PSA should be excluded when considering the diagnosis of a low-grade squamous intraepithelial lesion, specifically if the diagnosis rests on the interpretation of koilocytotic atypia.
