The authors propose a modification to the technique of lymphography by the addition to a radioactive isotope (I 131) of a vegetable colorant that permits the direct observation of the lymphatic tract during the surgical exploration.

The authors present their experience in the Instituto de Maternidad de la Plata, Argentina, from two aspects: 1) The antecedent of pregnancy in 185 cases of carcinoma of the cervix; they found that 36 of them had a pregnancy in a lapse of two years to the time of diagnosis. 2) In the examination of 640 pregnancies with some type of cervical pathology, 9 cases of carcinoma were found; this means an incidence of 1.4%. Some therapeutic attitudes are also presented.

There are various causes that can originate an extended class III: carcinoma, epithelial hyperplasia, trichomoniasis, nonspecific colpitis, pregnancy, vaginal atrophy, ectrapionitis. In the presence of an extended III it is necessary to make a careful examination of the neck (colposcopy examination flow, etc.) and perform directed biopsy in the presence of any suspicious image. Being the most frequent cause widespread trichomoniasis, yet we must not discard their possible association with carcinoma (two cases in our statistics) and make a colposcopic examination of the neck and repeat cytology once cured the condition.
