Primary intraosseous carcinoma of the jaws. Three new cases and a review of the literature.

Three new cases of primary intraosseous carcinoma are presented. The clinical features of these cancers often mimics odontogenic cysts, dental abscesses or periodontal disease; all benign dental conditions. This may delay the diagnosis and probably accounts for the poor prognosis associated with these tumours of 30-40% 5-year survival. A total of 24 cases of primary intraosseous carcinomas have been analysed, which includes reports collected from the literature and the three new cases presented in this paper.
