title: [Conjoined twins. Historical review].
abstract: Conjoined twinning is a rare and complex malformation of the newborn. In this study an attention is drawn to reports published in Icelandic historical logs. There are four examples of definite conjoined pairing and one uncertain. An embryologic background of conjoined twinning is introduced and new view of its pathogenesis, are proposed.
