AZUA-ROMEO, J. et al. Ameloblastic fibroma versus hyperplastic follicular cyst. Rev Esp Cirug Oral y Maxilofac [online]. 2004, vol.26, n.3, pp.187-191. ISSN 2173-9161.

Abstract: Ameloblastic fibroma (AF) is a mixed odontogenic tumor composed of mesenchymal tissue and odontogenic epithelium, accounting for 2% of all odontogenic tumors, while dentigerous or follicular cyst (FQ), second odontogenic cyst in frequency, is formed exclusivelly by soft conective tissue (mesenchyme). Nevertheless, hiperplastic fibrous sac may contain rests of odontogenic epithelium, showing a similar histologic pattern. The importance of an adequate differentiation lies in the treatment, which is slightly aggresive for AF, and regarding the biological behaviour of both lesions, since AF might become in an ameloblastic sarcoma, while over an FQ could develope an ameloblastoma or even a mucoepidermoid carcinoma.
