An unusual ovarian neoplasm diagnosed in a patient with rupture of unicornuate uterus during pregnancy: a case report.

ABSTRACT

Unicornuate uterus is a rare disease characterized with reduced fertility, and ovarian tumor diagnosed during pregnancy is uncommon as well. These two diseases have been reported separately. However, patient suffering from both diseases has never been reported before. The authors herein report a case of a 32-year-old Chinese woman presenting with a unicornuate uterus with no horn, who suffered from acute abdominal pain and intra-abdominal hemorrhage at 26 weeks gestation. Incidentally, a borderline ovarian tumor (BOT) and rupture of uterus were found during an urgent exploratory laparotomy. During the follow-up, ovarian tumor recurred in the first year after the operation. The authors suggest that BOT with micropapillary patterns should be paid much more attention to, other than only assessing the histological type. Furthermore, they also suggest that a slightly increased in serum CA-125 value should not be ignored.
