ABSTRACT
Ovarian cancer rarely complicates pregnancy. Usually these malignancies consist of germ cell tumors. Preserving maternal safety along with favorable neonatal outcome is a subject of debate in the management of ovarian cancer during pregnancy. In this report, the authors describe a 25-year-old primigravid woman who was diagnosed to with an ovarian immature teratoma which was diagnosed at 13th weeks of pregnancy during a routine sonography. She underwent oophorectomy at week 21 of her gestation. Then she received three cycles of BEP regimen (bleomycin, etoposide, and cisplatin) during her pregnancy until week 37 of gestation. At 36 weeks she delivered a male baby with mild glandular hypospadia who was otherwise normal. Management of immature teratoma after the first trimester of pregnancy is similar to non-pregnant patients and is safe for both the mother and the fetus.
