title: Fusion as the etiology of chimerism in monochorionic dizygotic twins.
abstract: In a dizygotic pregnancy within monochorionic placenta, findings consistent with chimerism were detected. Monochorionicity was confirmed by a combination of ultrasound, histological evaluation and DNA technology. Etiologic hypotheses are offered to explain this rare circumstance.
