    Study Notes

    Ameloblastic Fibroma Overview

    • Benign mixed odontogenic neoplasm
    • Consists of neoplastic odontogenic epithelium in actively proliferating connective tissue resembling the tooth follicle or dental papilla
    • Characterized by thin strands/cords of odontogenic epithelium

    Key Characteristics

    • Average age of onset: 14 years
    • Common location: Mandibular molar area
    • Painless, slow-growing lesion
    • Causes slight buccal and lingual cortical expansion

    Radiographic Features

    • Radiolucent areas, unilocular or multilocular
    • May resemble ameloblastoma

    Histological Features

    • Thin strands/cords of odontogenic epithelium
    • Peripheral layer of cuboidal/columnar cells surrounding stellate cells
    • Resembles dental lamina
    • Connective tissue is embryonic, proliferating fibroblastic cells, with minimal collagen
    • Often has areas of hyalinization, particularly juxta-epithelial, surrounding the epithelial component
    • Epithelial component consists of thin strands and cords
    • Background connective tissue composed of embryonic proliferating fibroblastic cells and little collagen
    • Juxta-epithelial hyalinization often present
