title: Truncal duplication: a case report.
abstract: Truncal duplication represents one of the rare forms of conjoined twins. We observed a male infant with a truncal duplication; in the host twin no pathology was found except an atrial septal defect and a large omphalocele. The parasitic twin was attached to the xiphoid region (xiphopagus) in an opposite and "horseriding" manner, was acephalic, and had multiple gastrointestinal, genitourinary, and skeletal anomalies. The junction site consisted of lipoid and muscular structures. Surgical separation was done without any difficulty. The abdominal defect was repaired primarily. The host twin is doing well.
