Seven pairs of twins, two monozygotic (MZ), two dizygotic (DZ), and three like‐sex pairs of unknown zygosity are described. The twin pairs were all discordant for omphalocele except for one pair of conjoined twins. The 8 infants with omphalocele represent 3.1% of the 253 infants with omphalocele, ascertained in an almost complete nationwide data set of live‐ and stillborn infants with abdominal wall defects in two decades in Denmark (1970–1989). The occurrence of twins with omphalocele was not significantly different from the occurrence of twins in the Danish population in the same period. To our knowledge this is the first report of the occurrence of twins with omphalocele in a systematic nationwide epidemiological study. © 2010 Wiley‐Liss, Inc.
