[Ovarian implantation of the embryo in IVF and ET--early mole with proliferative trophoblast].

OBJECTIVE

Case report of a very rare case of ovarian implantation after IVF and ET treated by laparoscopy.

DESIGN

Case report.

SETTING

Institute for the Care of Mother and Child, Prenatal Diagnostic Centre and Trophoblastic Disease Centre, Prague, Institute for Postgraduate Medical Education, Prague.

RESULTS

We observed implanted product of conception found within the ovarian stroma 35 days after ET. At laparoscopy, the genital sac appeared as an inconspicious haemorrhagic cyst, 2 cm in diameter. After dissection, in the intact sac appeared amorphous 2 mm embryo and 3 mm yolk sac. The trophoblast of the anchoring chorionic villi exhibited marked hyperproliferation and was classified as a proliferating mole.

CONCLUSION

The intact early product of conception exhibited trophoblastic hyperplasia.
