Ameloblastoma of the Jaws

Abstract

All the 49 jaw ameloblastomas reported to the Swedish Cancer Registry during the period 1958--1971 were re-examined, using the histopathologic criteria of odontogenic tumors adopted by WHO. Thirty-one cases (63.6%) fulfilled the criteria of simple ameloblastoma, whereas 12 cases were found to be other benign lesions and 6 to be malignant tumors other than ameloblastoma. The relationship between simple ameloblastoma, malignant ameloblastoma and other epithelial jaw tumors is discussed.
