Adnexal masses detected during pregnancy: A tertiary center experience

Objective: We aimed to evaluate adnexal masses in pregnant women who were referred to the gynecologic oncology department. Material and Methods: Data of the pregnant women referred to the gynecological oncology department between November 2016 and June 2019 with suspicion of adnexal malignancy were retrieved through the hospital's electronic medical records that included patients' demographic characteristics, gestational age, ultrasonographic, and magnetic resonance imaging findings, serum tumor markers, histopathological results. Patients with a spontaneously regressed adnexal mass, benign adnexal masses, and concurrent ectopic pregnancy were excluded. Results: The mean age of the patients was 30.9±0.87 years. The mean gestational age at diagnosis was 14.05±1.36 weeks and the mean gestational age at delivery was 35.9±1.23 weeks. The mean gestational age at diagnosis was 14.05±1.36 weeks. Twenty-five patients (59.5%) underwent laparotomy while 18 patients (40.5%) managed conservatively. The histopathological results were mucinous cystadenoma in 8 (32%) patients, mature cystic teratoma in 6 (24%) patients, borderline mucinous cystadenoma in 3 (12%) patients, borderline serous cystadenoma in 2 (8%) patients, serous cystadenoma in 2 (8%) patients, Brenner’s tumor in 2 (8%) patients, theca lutein cysts in 1 (4%) patient, and fibroma in 1 (4%) patient. None of the patients has malignant neoplasm. Conclusion: Adnexal masses at pregnancy should be referred gynecologic oncology department after the 17th week of gestation.
