The presence of myometrial fibres adherent to the delivered placenta has been recognized as an important histologic finding within the spectrum of placenta accreta/morbidly adherent placenta. Basal plate myometrial fibres (BPMF) are easily and not uncommonly recognized with careful examination of the basal plate, and although more research is needed to determine its significance, cohort studies have shown an increased risk for development of placenta accreta in a subsequent pregnancy.
