A benign but locally infiltrating neoplasm arising from tooth-forming tissues. It is more often intraosseous and less frequently extraosseous and occurs in the jaw. It is characterized by the presence of ameloblastoma-like epithelium, connective tissue stroma, ghost cells, and dysplastic dentin. Wide local resection is recommended for intraosseous neoplasms and enucleation for extraosseous neoplasms. [from
