Primary intraosseous carcinoma of the jaws – A review

Abstract

Primary intra osseous carcinoma of the jaws is a rare tumour supposedly originating from odontogenic epithelial residues. It is one among few odontogenic carcinomas arising in the jaws. Others include malignant ameloblastoma, malignant changes in odontogenic cysts and malignant variants of other odontogenic tumours arising from epithelium. The mandible has a greater propensity for involvement than the maxilla. Although certain lesions have been reported as having a well-defined border, most do not. There is no sign of new bone formation and just a very little amount of remaining bone in the lesion's centre, making the internal structure completely radiolucent. This review highlights the aetiology, features and treatment of  PIOC.
