[Rare forms of ectopic pregnancy in surgical data from the Women's Health Service--case reports].

Three rare forms of ectopic pregnancies are presented. Each case is interesting because of it's rare occurrence and because of difficulties in the setting of the diagnosis. Ultrasound diagnostics with modern equipment helps the gynecologist in the solving of diagnostic problems. The diagnosis of bilateral tubal pregnancy was established in our case also intraoperatively, and it was proved with a pathohistological finding. With each ectopic pregnancy there is a possibility that the same changes can occur on the opposite side also. Because of this possibility, an intraoperative revision is obligatory. Primary ovarian pregnancy is diagnosed intraoperatively. Our case also presents a rarity because of the size of the embryo. Simultaneous intrauterine and extrauterine pregnancy is interesting because of the setting of an on-time diagnosis, and because of a successful carrying out of the pregnancy and birth. Postoperative course had gone well in all the cases and the patients were released as cured, and one of them was released after childbirth.
