Persistent low-level elevation of serum human chorionic gonadotropin after termination of pregnancy: a rare case of peritoneal trophoblastic implant.

ABSTRACT

Peritoneal trophoblastic implant can occur after treatment of ectopic pregnancy. Similarly, after termination of intrauterine pregnancy, trophoblastic implants are rare but can be a complication of perforation during dilatation and curettage. We report an extremely rare case of trophoblastic implant on the myometrium, ovarian surface, and peritoneal wall 4 months after uncomplicated dilatation and curettage. To the best of our knowledge, this is the first case of peritoneal trophoblastic implant following dilatation and curettage without uterine perforation. Knowledge of this case is useful for the management of patients with persistent low-level elevation of serum human chorionic gonadotropin after termination of pregnancy.
