Demographic, clinical data and postoperative histopathologic diagnosis.


The incidence of an adnexal mass in all pregnancies was 0,02 % (29/14523). The median age of patients was 32 years (range, 20-41). The median gestational age at which adnexal masses were detected was 34.1 weeks (range, 7-41), and the mean gestational age at the time of surgery was 37 weeks (range, 14-41). Second trimester surgery was performed in 3 patients (10.3%), and time of cesarean delivery in 26 patients (89.7%). Postoperative pathology results of the patients were functional cysts in 9 cases (30%), teratoma in 9 cases (30%), cystadenoma in 6 cases (20%), endometrioma in 2 cases (6.7%), borderline tumor in one case (3,3%), and malignant tumors in 3 cases (10%).


Adnexes should be carefully examined with 1st trimester obstetrical USG and indication for surgical operation should be made more carefully.
