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.
