Abstract

Odontoameloblastoma (OA) is a rare mixed odontogenic tumor with both ameloblastic (epithelial) and odontoma-like (ectomesenchymal) features. It presents as a unilocular or multilocular radiolucent to mixed lesion with root resorption, boney expansion, and/or jaw pain. Microscopically, the epithelial component often resembles a follicular or plexiform variant of a conventional ameloblastoma. In contrast to an ameloblastoma, however, the surrounding mesenchyme consists of dental hard tissue in the form of a compound or complex odontoma. OAs behave similarly to conventional ameloblastomas and are treated by wide surgical excision. Because of the scarcity of reported cases, however, little information exists regarding this lesion. Here, we report a case of OA occurring in the mandible of a 51-yer-old African American female.
