The evaluation of abnormal cervical cytology during pregnancy can be c
hallenging. The development and continued improvement of colposcopy in
this evaluation has lead to a more conservative approach to this prob
lem. The proven safety and accuracy of colposcopy to rule out invasive
disease in pregnancy has all but eliminated the need for diagnostic c
onization of the gravid cervix. Close antepartum colposcopic observati
on of premalignant lesions with re-evaluation and treatment in the pos
tpartum period is now the accepted standard of care. The prudent use o
f cone biopsy when colposcopy is nonsatisfactory is a must but it shou
ld not be considered as adequate therapy for CIN once again stressing
the importance of postpartum re-evaluation.
