Ameloblastoma: Literature Review

[摘要] The ameloblastoma is a locally invasive polymorphic benign neoplasm composed of a proliferation of odontogenic epithelium in a fibrous stroma, classified within the benign tumors of above mentioned epithelium with a mature stroma without odontogenic ectomesenchyme. It represents the 11 and the 13 % of all odontogenic tumors. Its appearance is mainly during the fourth and fifth decade of life in any sex and in any age with a greater incidence between 20 and 50 years except the unicystic variety diagnosed between 20 and 30 years. This tumor has a lengthy and silent growth without obvious early sings, involving mainly the mandibular bone. Its therapeutical behavior is complex due to its propensity characteristic to relapse caused by the possible presence of peripheral microscopic lesions and by the multicentric origin of tumor.
