OBJECTIVE: The aim of this study was to determine the prevalence, clinical profile and histopathological types of all the cases of unicystic ameloblastoma in a Nigerian population.
METHODS: In this retrospective study, case files and biopsy reports of new cases of unicystic ameloblastoma seen at the University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria from 2009 to 2017 were retrieved and analyzed for gender, age on presentation, histologic type and site distribution.
RESULTS: A total of 52 cases of ameloblastoma were seen during the period under review among which unicystic ameloblastoma accounted for 19 (36.5%) of the cases. A male to female ratio of 1:1.4 was found. The average age on presentation was 25 years. The lesion was most common in the posterior mandible and the mural variant was the most common histological type.
CONCLUSIONS: The age, gender and site distributions of unicystic ameloblastoma are similar to previous reports but the distribution of the histological types is at variance with previous studies.
