Approximately one-fourth of the ovarian neoplasms and cysts are diagnosed incidentally during caesarean section. The possibility of malignancy should be considered although existence of ovarian malignancy in pregnancy is rare. A 24-year-old pregnant woman was admitted to our hospital at 38 weeks of gestation for cesarean section in view of Breech presentation, fortuitously during intraoperative pelvic examination; a large ovarian unhealthy mass was detected. Thus, the team proceeded with oophorectomy and removal of the tumor. Histopathological findings, including immuno-histochemical study, led to the diagnosis of juvenile granulosa cell tumor (JGCT). In this report, the histological features of the JGCT and the optimal management of such adnexal masses during pregnancy are discussed. A JGCT that is confined to the ovary appears to have an excellent prognosis and can be treated by unilateral oophorectomy.
