description

Objectives. The purpose of this study was the review of 50 ameloblastoma in Nigerian patients observed in the Hos- pital of Ibadan. Ameloblastoma represents nearly 1% of all neoplasm located in the oral cavity. In 80% of cases it could be found in the mandible: 70% of these involving the molar region or the ascending ramus, 20% the premolar region and 10% the anterior part. Ameloblastoma is considered a benign neoplasm with slow growing-pattern and lo- cally aggressive behaviour. Methods. We collected the clinicopathologic data of 50 ameloblastoma from the files of the Hospital of Ibadan. Results. The 50 ameloblastoma occurred in patients from 8 years to 64 years, 25 cases (50%) were in their 3rd decade of life (20-29 years). Males were more frequently affected than females (27 to 23). On the basis of clinicora- diological findings, ameloblastoma were divided into 3 groups: solid or multicystic, unicystic and peripheral. The solid ameloblastoma represents nearly 60% of all cases (29 cases); it has a tendency to be more aggressive than the oth- er types with a higher incidence of recurrence; there were also 20 cases of unicystic and 1 of peripheral. After the surgical treatment we reported 7 recurrences. Conclusions. This review confirms the evidence of literature about amelobastoma: the prognosis for ameloblastoma is more dependent on the method of surgical treatment rather the histologic type of tumour.
