Atypical Proliferative ameloblastoma with a Rare Histopathological Feature and Review of Literature

摘要

The ameloblastoma, because of its aggressive clinical behavior and its histological feature apparently benign, constitutes a puzzling paradox. Some hypotheses concerning this strange clinicalhistologic contradiction are analyzed, as well as the additional paradox represented by the neoplastic parenchyma itself, in which a tissue consisting of cells nominally able to form enamel do not elaborate any of the calcified dental tissues. Here I am presenting a rare case report of ameloblastoma having a rare histopathologic picture of combination of multiple histopathologic types.
