title: Unusual human chorionic gonadotropin patterns in pregnancies of undetermined location.
abstract: Three abnormal pregnancies demonstrating a previously unreported pattern of hCG production and clearance are reported. Further, the anatomic site of trophoblastic implantation remained unknown despite through surgical exploration. A conservative approach, including close monitoring of serum beta-hCG levels, resulted in spontaneous resolution in two cases. One women was treated successfully with methotrexate.
