Cranio-facial and humeral melorrheostosis.

First described by LERY and JOANNY in 1992, melorrheostosis is an uncommon linear hyperostosis of unknown aetiology, which may be associated with soft tissures changes. Although all bones may be affected, cranio-facial involvement is very rare. Only six such cases have been found in the literature. This report describes a case of cranio-facial and left humeral melorrheostosis with symptomatic radial nerve involvement. Resection of the melorrheostotic bone was performed because of involvement of the radial nerve.
