Abstract 【Abstract】Objective To explore the clinical characteristics of the co-existence of maternal mature ovarian
teratoma and fetal immature sacrococcygeal teratoma (SCT). Methods The Obstetrics & Gynecology
Department of PLA Army General Hospital treated a pregnant woman diagnosed as co-existence of maternal mature ovarian teratoma and fetal immature sacrococcygeal teratoma in November 2016. The clinical characteristics of the case were analyzed. Results The patient was admitted to hospital because the blood pressure was not stable and there was a lump in the fetal sacrococcygeal region at 31+5 gestational weeks. A cyst in left ovary of the woman was detected by ultrasound at 12 gestational weeks, which size was 4.1 cm×3.8 cm×3.6 cm. A sacrococcygeal lump of the fetus was found by ultrasound at 22+3 gestational weeks, which size was 4.6 cm×5.0 cm×3.3 cm. With the gestation process, the sacrococcygeal lump of the fetus grew rapidly. Caesarean section was carried out because NST showed irresponsive result at 32+1 gestational weeks. The newborn was female who died at one hour after birth. The tumor of the newborn was solid, irregular and festering at surface, which diameter was about 15 cm. The tumor caused severe deformation of the hip and left leg. Pathological biopsy revealed that the mother's tumor was a cystic mature teratoma and the baby's tumor was an immature teratoma. Conclusions The co-existence of maternal and fetal teratomas is rare. This report is the ?rst case with co-existence of maternal mature ovarian teratoma and fetal immature SCT. The prognosis of the fetus is very poor.
