title: [Complicated placental chorioangioma: infrequent cause of premature labor].
abstract: We report a case of a 32 week pregnant patient who was admitted to our ward in preterm labor. After delivery, the examination of the placental tissue showed a large pedunculated tumor, complicated with torsion. Histology of the tumor revealed a placental chorioangioma. We propose that the complication of the tumor is the etiologic factor that brought about preterm labor in this patient.
