Background: Pregnancy complicated by endodermal sinus tumor (EST) of the ovary has rarely been reported. Case: A huge ovarian EST causing bowel obstruction was found in a 22-year-old patient at 34 weeks of gestation, Abnormally high alpha-fetoprotein (AFP) levels suggested a malignant germ cell tumor of the ovary. The patient was submitted to cesarean section and fertility sparing surgery, and then received four courses of combination chemotherapy. There was no evidence of recur­rence 19 months after initial treatment but transvaginal ultrasound (US) evaluation showed an intrauterine pregnancy of six weeks. We delivered a 3,200 g healthy male baby with Apgar scores of 8 and 9 by elective cesarean section at 39 weeks of gestation. Conclusions: Successful outcome of a second pregnancy is possible after treatment with fertility sparing surgery and combina­tion chemotherapy for an endodermal sinus tumor associated with a first pregnancy. Moreover checking of weekly AFP levels and performing monthly abdominal US could be effective for surveillance of these pregnancies. However management of EST during pregnancy should be based on consideration of the patient's presenting condition, preferences, and gestational age.
