Ameloblastic carcinoma (AC) is a rare and aggressive malignant epithelial odontogenic tumor which may arise either from the mandibula (66.6%) or the maxilla (33. %3). Besides being formed de novo the tumor can develop from a pre-existing ameloblastoma or odontogenic cyst. The clinical course of AC is typically aggressive with extensive local destruction.
