Ameloblastoma Part 1

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Ameloblastoma is an aggressive odontogenic tumor:
    • That forms from odontogenic epitheliumwithin a mature fibrous stroma devoid of odontogenic ectomesenchyme.
  • Although classified as a benign tumor:
    • Ameloblastoma is also the most common odontogenic tumor of epithelial origin with severe clinical implications.
  • Ameloblastoma has a locally aggressive growth pattern:
    • About 70% of cases undergo malignant transformation
    • Up to 2% metastasize to other sites
  • Ameloblastoma:
    • Constitutes about 14% of all jaw tumors and cysts
    • It is the most prevalent odontogenic tumors in developing countries
    • The global incidence of ameloblastoma is:
      • 0.5 cases per million persons per year:
        • It is a the most common odontogenic tumor in:
          • Africa and China
        • In the Western hemisphere:
          • Ameloblastoma is second to odontoma as the most common odontogenic tumor:
            • But the African American population is five times more likely to develop ameloblastoma compared to the Caucasian population.
    • Most patients with ameloblastoma:
      • Are between ages 30 and 60 years:
        • But average age at time of diagnosis varies from continent to continent estimated to be approximately:
          • 42.3 and 30.4 years in Europe and Africa, respectively.
    • Only 10% to 15% of ameloblastoma cases occur in the pediatric population:
      • But this can be as high as 25% in Africa and Asia
  • Ameloblastoma histologically:
    • Resembles the enamel organ of a developing tooth that has no intention of forming dental hard tissues:
      • Because the stroma lacks the properties of dental mesenchyme.
    • Despite the similarities:
      • It is intriguing that ameloblastoma still displays a distinctive clinically invasive and aggressive growth pattern
  • Due to naivety and limited healthcare facilities, ameloblastoma patients in developing countries often present with massively grown lesions before seeking care
