During pregnancy there ~s increased vascularity and oedema of the lower genital tract. The cervix shows hyperplasia of its glands and microscopically there is prominence of the basal cells near the squamocolumnar junction ( Pritchard and MacDonald, 1976 ). In a colposcopic study made by Kiguchi and Suda ( 1984) it was found that the developmentof metaplastic squamous epithelium is more likely to occur in the 3rd trimester with a difference in its development between primigravidae and multigravidae. During pregnancy the cervix becomes everted especially in the primigravida exposing the transformation zone where premalignancy and malignancy develop and the endocervical limit of this zone can be examined colposcopically in almost all patients ( Duncan 1981) • As the m a j 0 r i t Y 0 f the pati e n t s wi th precancerous lesions of the cervix now fall into the childbearing age group pregnancy provides a suitable occasion to examine them ( McDonnell et a1. 1981). Shingleton and Orr ( 1983 ) ,. emphasized that the routine use of cytological and colposcopical screening during antenatal care has been responsible for increasing the number of patients with early stages of cervical neoplasia.
