BOTERO GUTIERREZ, Nora et al. Ameloblastic fibroma associated with a compound odontoma: importance of the histopathological study. Rev Esp Cirug Oral y Maxilofac [online]. 2013, vol.35, n.4, pp.175-180. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2012.01.004.

The ameloblastic fibroma is a benign mixed, rare odontogenic tumour, which accounts for 2% of all odontogenic tumours. It is slow growing, and more common in children and young adults. It is composed of embryonic fibrous connective tissue and early odontogenic epithelium, and characterised by the proliferation of epithelial and mesenchymal tissue. It appears most frequently in the jaw area of molars and premolars of young patients with no sex predilection, and is sometimes associated with an impacted tooth. This article aims to describe a clinical case of a child in the second decade of life, with apparent anodontia in the maxilla, which was asymptomatic and later diagnosed as an ameloblastic fibroma in the left side maxilla incisors area. A brief review of the literature and differential diagnoses was carried out, including an analysis of its clinical and histological features, and the therapeutic approach to take. Conservative surgical excision followed by curettage seems to be the most appropriate treatment option. It should be noted that the recurrence rate is 18.3%, mainly due to incomplete excision of the lesion. Radiographic controls should be performed six months postoperatively, and every year for the following five years.
