Dubowitz' syndrome with special characteristics.

The Authors describe the main characteristics of Dubowitz' syndrome: retarded growth, microcephaly, cranio-facial deformations and dysmorphia of the extremities, psycho-motor development varying between normal and retarded, thin hair, cryptorchism, hyperactivity and others. They report a case which was brought to their attention in which, in addition to numerous anomalies and dysmorphia which justify its inclusion in Dubowitz' syndrome, there was marked bilateral metacarpal hypoplasia with strongly and permanently adducted thumbs. The aim of this report was to add to the mosaic of data relating to this highly polymorphous syndrome.
