Definition
========================================================================

● Cells from PeriMenopausal women

Clinical features
========================================================================

● Significant cause of ASC overdiagnosis in women ages 40 to 55 years (Am J Clin Pathol 2005;124:58)
● ASCUS appears to have a particularly low positive predictive value for SIL in perimenopausal women, and therefore most likely is overcalled in this age group; this may be attributable in part to air-drying artifact and subtle atrophic changes (Cancer 2001;93:100)
● Reporting benign EMs for premenopausal women 40 years and older has little clinical significance (Am J Clin Pathol 2005;123:571)
● ASC-H is associated with HSIL in 22% in perimenopausal women (Am J Clin Pathol 2006;126:381)

Cytology description
========================================================================

● Squamous cells with enlarged, smooth, bland nuclei in perimenopausal women
● In early menopause, there is an intermediate cell maturation pattern (DeMay: The Pap Test: Exfoliative Gynecologic Cytology (1st Ed); ASCP, 2005)
