Our presentation of four cases demonstrates the essential features of limb-
body wall complex (LBWC), representing a compound anomaly pattern in body-w
all defects. The diagnosis of this entity is based on two of the three foll
owing characteristics: (1) exencephaly/encephalocele and facial clefts; (2)
thoraco- and/or abdominoschisis; and (3) limb defects. A definite associat
ion with internal anomalies and severe kyphoscoliosis makes a more distinct
concept of the pathogenesis reasonable. Limb-body wall malformations resul
t from a malfunction of the ectodermal placodes involving the early embryon
ic folding process. The poor prognosis of LBWC calls for early antenatal di
agnosis.
