[The frontonasal dysplasia syndrome (DeMyer's syndrome) in a newborn aged two weeks].

A description is presented of a rarely observed frontonasal dysplasia (DeMyer's syndrome) whose diagnosis confirmed by X-ray and ophthalmological examinations was based on demonstration of a wide midline cleft of the facial skeleton, hypertelorism of eyes, and coexisting severe and infrequently occurring in this syndrome deformity of lower extremities. The authors think that the cause of DeMyer's syndrome in this case should be sought in the action of many various harmful factors.
