Tricho-rhino-phalangeal syndrome

Summary Two cases of tricho-rhino-phalangeal syndrome are described. This syndrome is one of the well differentiated diseases in the subgroup of peripheral dysostoses. Our cases conform with the condition as reported by Klingmueller and Giedion. The features which help to identify this entity are (I) peculiar facies (2) sparse hair (3) hand and feet deformities (4) usually some shortening of stature. Two additional clinical findings are stressed–bat ears and mental retardation. The importance of radiographic differentiation from other diseases with peripheral ossification disturbances and peripheral dysostoses syndromes, and specifically Thiemann's disease, is stressed.
