Pattern of Histologic Variants of Ameloblastoma in a Secondary Health Care Facility in Lagos State: A 5-Year Retrospective Study

Abstract

Background: Ameloblastoma is a benign epithelial odontogenic neoplasm which is common among the dwellers of sub-Saharan Africa.  The various histologic types have been elucidated.

Aim: This study aimed to assess the prevalent histologic types of ameloblastoma in a  Lagos secondary health care facility.

Materials and methods: A five-year retrospective review of histopathologically diagnosed slides  was done. Data extracted include the age, gender, location, ethnicity, and histologic variants, which were analysed with SPSS version 26.  Percentages, ratio, mean, standard deviation were determined, and p-value ⩽ 0.05 was considered significant.

Result: A total of 77  histopathologically diagnosed ameloblastoma slides were included in this study. Males were more affected than females in ratio 1.2:1  with the mean age 33.61±13.3. Ameloblastoma was commonest in the third decade of life and more in the mandible than maxilla. The  commonest histologic type was the conventional/follicular type which occurred more in males and this was followed by the  unicystic/intraluminal type.

Conclusion: The commonest histologic variant was the follicular (conventional) and occurred more in males.  This was followed by the intraluminal (unicystic) histologic variant that was commoner in females in this Lagos State secondary health  care facility.
