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.
