[Peritoneal hemorrhage caused by trophoblast tissue implanted on the peritoneum 6 weeks following induced abortion]

A case of heavy intraperitoneal bleeding from perimetrical implanted trophoblast tissue on the uterus was reported following artificial abortion. The six weeks previously terminated pregnancy was verified by transvaginal ultrasound examination, the unrecognised simultaneous extrauterine pregnancy was excluded. The mechanism of peritoneal implantation of trophoblast tissue is unknown. The authors reported the successful conservative treatment and analyzed possible origin of this rare localisation of trophoblast tissue.
