Epiphyseal osteochondromas with autosomal dominant inheritance and multiple parosteal bone proliferations.
The familial cases of dysplasia epiphysealis hemimelica (DEH), or Trevor's disease, are thought to represent dominant carpotarsal osteochondromatosis (DCO). Only three families affected by DCO have been reported so far in the literature. We report a fourth family: a 10-year-old girl, her father, and his cousin. Unlike the other reported cases of DCO this family had no carpal or upper limb epiphyseal osteochondromas and many of the other reported associations. The only consistent associated finding in our cases was the presence of multiple parosteal osteochondromatous proliferations. The findings of our cases are, therefore, unique in many ways. These cases may represent a variant of dominant carpotarsal osteochondromatosis or may represent a new entity.
