Placental Teratoma Case Report and Review of the Literature

De Ganzo Suárez Tania

Objective: Placental teratoma is a very rare no trophoblastic benign tumour. The tumour we present lays between amnios and chorion. It contains disorganized tissues (skin, bone, fat, etc.). Lack of a recognizable umbilical cord and no recognizable skeletal development are used as a differential diagnostic criterion for placenta teratoma. In our case umbilical cord was absent; however, the tumour was connected to the placenta by a vascular channel covered only by fetal membranes without Wharton´s jelly. We present a case to review the literature.

Material and methods: A 29 years old woman and 37 weeks of gestation. On the scan we found out a heterogenous mass of 8, 3 × 8, 5cm arising from the placenta.

Results: The diagnosis of the placental teratoma is based on prenatal ultrasound and histological examination of the placenta. This tumour does not appear to increase the risk of a fetal malformation. The differential diagnosis must be with fetus acardius amorphous. Maternal and fetal outcome were good.

Conclusion: Placental teratoma is a very rare no trophoblastic benign tumour.
