Abstract

Placenta surface cyst classified subamniotic hematoma, subchorionic hematoma and subchorionic cyst by histological finding. These cysts did not affect the obstetrical outcome according to the previous report. However, we experienced that the subamniotic cyst compressed the umbilical cord to result in fetal deceleration. We report this case with brief review of literature.
