Melorheostosis Involving the Craniofacial Skeleton

Abstract

Melorheostosis is a rare bone disorder, usually affecting the long bones and adjacent soft tissue. It was originally described by Leri and Joanny in 1922, after its classic x-ray features of flowing hyperostosis resembling dripping candle wax. There have been fewer than 10 reported cases of craniofacial involvement, and in most instances these have also involved the appendicular skeleton. The authors report a case of melorheostosis with isolated craniofacial involvement, describe the clinical course and radiologic and histologic features, and review the pertinent literature.
