This article contains a brief description of the placenta in multiple pregnancy, including a classification based on embryogenesis. The biologic and clinical importance of recognition of the different types of twin placentas is emphasized. Finally, a classification of the pathological lesions seen in these placentas, either because of the twinning process or simply associated with it, is proposed.
