title: Autosomal dominant type of endosteal hyperostosis with unusual manifestations of sclerosis of the jaw bones.
abstract: We report three cases of autosomal dominant type endosteal hyperostosis which occurred in one Japanese family. A new pattern of sclerotic changes in the jaw bones is evident. In all members of the family there was a symmetrical thickening of the diaphyseal cortices of the long bones. The affected bones were only minimally widened and the epiphyses and metaphyses were spared. Endosteal sclerosis of the neurocranium was present with loss of the diploë. The sclerotic changes included enlargement and mottled sclerosis of both the maxilla and mandible, with multiple embedded teeth and odontomas. The ramus of the mandible was spared. Severe sclerosis of the jaw bones was present only in a 28-year-old woman. The 2-year-son showed only focal sclerosis in the mandible, and his grandmother had minimal changes in the skeleton.
