Ameloblastoma is a rare odontogenic neoplasm of the mandible and maxilla, with multiple histologic variants, and high recurrence rates if improperly treated. The current mainstay of treatment is wide local excision with appropriate margins and immediate reconstruction. Here we review the ameloblastoma literature, using the available evidence to highlight the change in management over the past several decades. In addition, we explore the recent molecular characterization of these tumors which may point towards new potential avenues of personalized treatment.

Objective: To analyze the frequency, clinical, histopathological, and radiological characteristics of ameloblastoma in Nigeria over the course of two decades.
Study Design: A retrospective analysis was conducted on 371 cases at a Nigerian university hospital between 2000 and 2023. Age, gender, site, histological variants, tumor size and duration were analyzed.

This report describes an atypical case of canine acanthomatous ameloblastoma (CAA) with mucinous glandular differentiation in a 12-year-old male Chihuahua with a right mandibular mass. Initially diagnosed as CAA by biopsy, computed tomography revealed bone lysis, prompting surgical excision. Histological examination showed lobular growth with two distinct neoplastic cell populations: typical CAA-like cells and a minor glandular structure population.

Purpose: Ameloblastoma is a benign tumor originating from odontogenic epithelium with a global incidence of about 0.5 cases per million persons per year. The overall recurrence rate of ameloblastomas range from 55% -90%.

Ameloblastoma represents a rare and locally aggressive odontogenic neoplasm, notable for its histopathological diversity. Among its subtypes, the desmoplastic and plexiform variants are relatively rare, with the hybrid form, encompassing both architectural patterns, representing an even more exceptional entity. This article delineates the clinical, radiological, and histopathological profile of a 45-year-old male presenting with pain persisting over the past month in the right posterior maxillary region.

Peripheral ameloblastoma is a rare, benign, slow-growing odontogenic neoplasm prevalent in the mandible. It originates from the odontogenic epithelium and its remnants, and its histological characteristics are identical to those of intraosseous ameloblastoma. It is less aggressive and invasive than its intraosseous variety, with a low recurrence rate.
