Massive granular cell ameloblastoma with metastasis: report of a case.

The case of a woman with a massive recurrent anterior mandibular ameloblastoma of 45 years' duration that showed metastasis is presented. The aggressive nature of the tumor, its management, and the eventual outcome are discussed. Ameloblastomas, particularly after their first recurrence, must be viewed as potentially life-threatening lesions. Adequate resection early in the onset of such tumors may result in more successful and predictable results.
