title: Pathogenesis of congenital malformations. An hypothesis.
abstract: An hypothesis of neural crest injury, derived from a radiologic analysis of thalidomide deformities, is suggested as a possible pathogenetic mechanism of dysmelia and its associated visceral defects. Supportive evidence from a variety of sources is presented, and the hypothesis is shown to provide a unifying concept for a number of previously unrelated facts.
