Trichorhinophalangeal Syndrome (Report of 4 Cases in Two Generations of One Family)

Four cases of trichorhinophalangeal syndrome in two generations of one family were reported.The clinical and X-ray findings were described.The pathological basis of the syn-drome was metaphysical dyschondroplasia combined with ectodermal dysplasia. The pathological changes mainly involved on the epiphyseal cartilage plates of the fingers and toes rexulting in cone-shaped epiphyses and early closure of the epiphyseal line with shortening of the limb-end The rela-tionship between the basic X-ray findings and the pathological basis was discussed.The main points of diagnosis were suggested.The authors proposed that the triangular or semilunar shaped sclerosis in the ear-like articular surfaces of both ilia may be a clue to radiologic diagnosis of tri-chorhinophalangeal syndrome.
