[A contribution to the study of ovarian cancer during pregnancy and the puerperium. 3 case histories (author's transl)].

The authors have seen three cancers out of 27 organic ovarian tumours which were diagnosed and operated on during pregnancy and the puerperium in 16790 deliveries. They recall the circumstances under which the condition was discovered and the difficulties in diagnosing it. They point out particularly the value of ultrasound and frozen section histological examination.
