Diagnosis: Multicystic ameloblastoma

Ameloblastoma is the most common neoplasm of odontogenic epithelium.¹ These tumors are benign, locally aggressive, and slow growing. More than 80% of ameloblastomas are located in the mandible, with the remainder occurring in the maxilla. About 17% of the cases are associated with the presence of impacted teeth. The peak incidence of ameloblastoma is between the second and fourth decades of life.²

Ameloblastomas are thought to arise from the enamel organ of teeth, epithelial rests of Serres or Malassez, epithelial lining of odontogenic cysts, or basal layer of the oral mucosal epithelium. They are broadly classified into peripheral (extraosseous) and central (intraosseous) types. The central type, based on histologic features, is further subcategorized into unicystic and multicystic variants.¹ Peripheral ameloblastomas, which account for 2% of all ameloblastomas, arise in soft tissue around alveolar bone, with two-thirds occurring in the mandible. They are much less aggressive than the central intraosseous type. . . . [Full Text of this Article]
