Case report
A 12-year-old girl was referred to the Oral and Maxillofacial Surgery Service at Hospital Nove de Julho (Instituto Oncológico), Juiz de Fora (MG), Brazil, in June 2006, with a left facial swelling and a complaint of 6 months’ mild pain due to masticatory trauma in the gum. Oral examination revealed a fixed and protruding mass, tender to palpation and covered with a whitish and red mucosa and pseudo-membrane (Fig. 1). Orthopantomography revealed a poorly defined radiolucency extending from the
Discussion
AFS are rare, true, mixed neoplasms exhibiting a benign epithelial component and malign ectomesenchymal cells2, 3, 6, 7, 9. Some authors consider that AFS are the malignant counterparts of the AF1, 3, 6, 9. AFO are considered possible precursor lesions for AFDS and AFOS2. Carlos et al.2 state that, 64 cases of AFS and 14 cases of AFDS/ AFOS have been reported in the English-language literature, up to 2005. To the authors’ knowledge, the case presented here is the fifteenth case of AFDS/AFOS

2018, Journal of Stomatology, Oral and Maxillofacial SurgeryCitation Excerpt :And Gatz et al. [16] reported a case of AFOS in patient that presented a hamartomatous complex odontoma, not an AFO, 6 years earlier. Some cases of AFDS and AFOS showed large areas of the resected tumor with microscopic features of a benign tumor [17,19]. It is therefore important that a histological evaluation of the whole specimen should be carried out, because in AFDS and AFOS the epithelial component is very similar to the one in AFD and AFO, respectively, but the mesenchymal component may show increased cellularity with a sarcomatoid nature in isolated areas.

2013, Journal of Oral and Maxillofacial SurgeryCitation Excerpt :It has been observed that approximately one third of AFS cases developed in a recurrent AF. Likewise, AFO is thought to be the precursor for AFOS.1,2 The present case is thought to develop from an AFO; although large areas of the resected tumor retained the microscopic features of a benign tumor, with the induction of normal-looking dentinoid and enameloid, in other areas the sarcomatoid component was dominant, with the induction of dysplastic dentinoid, cementoid, and enameloid.
