Pathogenesis of microglandular hyperplasia of the cervix uteri.

Microglandular hyperplasia of the cervix has commonly been associated with pregnancy and oral contraceptive use. In a review of 22 cases seen over the last 10 years, 6 of the cases were not associated with hormonal changes. The idiopathic presentation of this lesion is reviewed. Microglandular hyperplasia of the cervix mimicking clear cell carcinoma of the cervix occurred in a 26-year-old woman with a history of in utero stilbestrol exposure who was taking an oral contraceptive. The differentiation of these two unusual lesions of the cervix is discussed.
