title: Concordant body stalk anomaly in monozygotic twinning--early embryo cleavage disorder.
abstract: We describe a case of concordant body stalk anomaly in monozygotic twins that manifested with umbilical cord agenesis, evisceration of abdominal contents, and multiple gastrointestinal, genitourinary, and skeletal anomalies. Body stalk anomaly in twin gestation is extremely rare and poses an embryological interest. We suggest that the hypothesis of 'incomplete twinning' might contribute to the pathogenesis of this syndrome complex.
