Borderline micropapillary serous tumor of the ovary detected during a cesarean section due to a transabdominal cervico-isthmic cerclage in a patient with congenital cervical hypoplasia: a rare case.

A young woman with polycystic ovary syndrome and congenital cervical hypoplasia conceived with clomifen citrate treatment after placement of a transabdominal cervico-isthmic cerclage. Her pregnancy successfully reached term and cesarean section was performed to preserve the cerclage for the next pregnancy; when the ovaries were explored an irregular structure was detected on the left ovary. A wedge biopsy was done and the pathological assessment of the specimen was borderline micropapillary serous tumor of the ovary. The patient wanted to preserve her fertility, therefore a fertility-sparing staging surgery was performed six months after the cesarean section. There was no residual tumor in the left ovary, but there was a borderline tumor in the right ovarian biopsy specimen (frozen section was negative). Two months after staging surgery the patient conceived with IVF and delivered twins at the 33rd week of pregnancy with cesarean section. At her second cesarean section the right ovary and abdomen appeared normal on inspection, but the cerclage tape was in the endocervical canal and was thus removed. To our knowledge this is the second reported case of transabdominal cerclage tape migration into the endocervical canal. The patient is clinically disease-free 18 months after her second cesarean section. The clinical findings, treatment modalities, management and prognosis are discussed together with a literature review of a patient with a serous borderline ovarian tumor and congenital cervical hypoplasia.
