title: Two live-born infants with trisomy 22.
abstract: The autopsy findings and karyotypes of two live-born fetuses with full trisomy 22 are discussed. Confined placental mosaicism was documented in one of the two cases. Confined placental mosaicism may play a role in the intrauterine survival of some trisomy 22 conceptions.
