The ameloblastoma is considered to be a slowly growing, locally invasive tumor with a high rate of recurrence if not removed adequately. Ameloblastoma generally dose not metastasize to distant places. In very ray case, ameloblastoma changed its
histologic appearance to carcinoma or showed distant metastasis, these generally called malignant ameloblastoma. Inadequate surgical procedures, radiation therapy, and a long duration of this tumor seem to have significant relation to the
development of
metastasis. Therefore, adequate surgical treatment of the primary lesion plays an important role in the prevention of metastasis postoperatively.
This report described an instance of malignant ameloblastoma and review of literature.
