Abstract: The aim or this paper is to evaluate the clinical, radiographic, and histopathological findings and treatment modalities in all cases of ameloblastomas treated at the Sao Paulo Cancer Hospital, between 1953 and 2003. 121 case reports were retrieved from the medical files. Data were reviewed and statistical analysis was performed using Kaplan-Meyer method and Cox proportional risk model. The patients' age ranged from 2 to 82 years (mean 33.2 years), with a slight female prevalence. Most cases were located in the posterior mandible (80%). Radiographically, 60% showed a multilocular pattern. 113 casees were solid ameloblastomas, and plexiforme Subtype was the most common. Solid tumours were treated by wide resection, curettage and criosurgery, or curettage alone, and unicystic tumours by curettage and/or cryotherapy. The global mean recurrence rate was 22%, with a mean follow-up of 9.7 years. The ameloblastomas were predominantly solid, affecting the posterior mandible. Important factors for outcome were radiographically multilocular lesions, the presence of ruptured basal cortical bone and histologically follicular tumours.
