The Ameloblastic Fibroma epithelial tissue could be confused with the most common odontogenic tumour, the Ameloblastoma. Therefore the mesenchymal component is histologically important in differential diagnosis. [7] The mesenchymal stroma in normal development is a rich myxoid connective tissue.

Multiple adenomas or diffuse islet cell hyperplasia commonly occurs. About 30% of tumors are malignant and have local or distant metastases. [5]
