title: Sex-discordant monochorionic twins with blood and tissue chimerism.
abstract: We report on a pair of normally conceived monochorionic/dizygotic (MC/DZ) sex discordant twins. The comparison of blood and skin genotypes revealed that the chimerism was also present in the skin. We conjecture about the developmental origins of this case.
