Pierre Robin syndrome with hyperphalangism-clinodactylysm of the index finger: a possible new palato-digital syndrome.

ABSTRACT

A nine day old boy who had the Pierre Robin syndrome also had an unusual associated hand malformation consisting of bilateral clinodactyly of the index finger. A supernumerary phalanx was inserted between the second metacarpal and the proximal phalanx of both index fingers with a radial deviation of the same phalanx. The same hand malformation has been previously described in three patients who had either the Pierre Robin syndrome or isolated cleft palate. On the basis of ours and the three previous cases, the existence of a new palato-digital syndrome is suggested.
