Ameloblastoma unicístico mural com componente intraluminal revisão e relato de caso Mural unicystic ameloblastoma with an intraluminal component: a review and case report

According to the World Health Organization, ameloblastomas are benign odontogenic tumors of epithelial origin that present characteristics of local infiltration and a high rate of recurrence. Considering their frequency, aggressiveness, histopathological diversity, capacity of recurrence and the controversy regarding forms of treatment, there are many reasons why they have been frequently mentioned in dental and medical literature. Unicystic ameloblastoma is a variant form that presents a favorable prognosis and low rate of recurrence, even when treated by conservative procedures such as enucleation or curettage. Clinically and radiographically, it may resemble a cystic lesion, such as a follicular cyst, demanding a precise diagnosis in order to ensure the correct treatment and prevent recurrence. The case reported here is that of a 20-year-old female with an increase in facial volume in the posterior region of the jaw. A diagnosis of unicystic ameblastoma was confirmed by aspiratory puncture, followed by an excisional biopsy and histopathological analysis. The patient successfully underwent enucleation of the tumor and bone curettage. The patient has been followed up for two years with no signs of recurrence of the tumor.
