title: Failure of placenta to produce hPL in an otherwise uneventful pregnancy: a case report.
abstract: We report a further case of human placental lactogen (hPL) deficiency associated with a normal pregnancy. To our knowledge this is the first report in which the examination of placenta by means of the immunoperoxidase technique confirmed that hPL was absent from the trophoblast.
