title: [Ultrastructural study of placentas from HIV seropositive women].
abstract: Eleven placentas from seropositive women for HIV, were analyzed. In three cases the material came from first trimester abortions and the other eight from term pregnancies. In five cases retroviruses were identified, similar to HIV in the placental tissue. It was demonstrated for the first time the internalization of a retrovirus and its presence in the syncytiotrophoblast. It is communicated for the first time the presence of one cell in the placental stroma different to Hofbauer's by its granules type.
