Ameloblastic fibroma is a mixed intraosseous & true biphasic tumour consisting of proliferating odontogenic epithelium in ectomesenchyme having two sub types: neoplasm and a hamartomatous lesion. Histopathologically, it reveals epithelial strands and islands resembling the embryonic enamel organ, within the cellular and primitive connective tissue stroma mimicking the dental papilla. It is well encapsulated and shows an innocuous benign behavior. This book emphasizes the most current concept of pathogenesis & management making diagnosis easier.
