The tricho-rhino-phalangeal syndrome--a case report.

The diagnosis of tricho-rhino-phalangeal (TRP) syndrome may sometimes be confused with hypohidrotic ectodermal dysplasia (HED). Some of the facial features are similar but the hands of patients with TRP often have short distal phalanges, deviation at the proximal interphalangeal joints and, radiologically, a specific distribution of cone-shaped epiphyses. This report describes a case of TRP syndrome with previously unreported hypodontia, which increases the similarity between TRP and HED.
