Resumo: Female, 86 years old, with a lesion in the anterior region of the mandible with five previous surgical procedures and recurrences in all of them. Clinical examination revealed a hardened consistency, firm to palpation and normochromic color. Computed tomography showed a multilocular hypodense lesion with cortical bone destruction. The histopathological analysis showed a neoplastic lesion of odontogenic origin, characterized by the proliferation of epithelial cells grouped in a follicular pattern, peripheral palisade with nuclei exhibiting inverted polarity in the center of these enamel islands. Sometimes, the centers of these islands show squamous metaplasia with formation of keratin pearls, characterizing an acanthomatous pattern. The diagnosis of Ameloblastoma was established. The patient awaits surgical excision of the lesion.
