ABSTRACT
Ameloblastic fibro-odontoma (AFO) is a mixed odontogenic tumor, which has an epithelial and mesenchymal component. It can be observed in imaging tests as a radiomixed lesion, with some authors claiming it represents only the predecessor of an odontoma. Epidemiologically, it appears between the second and third decade of life, predominantly in males and with a predilection for the posterior area of the mandible. This lesion presents a good prognosis and it responds well to enucleation by curettage with a low rate of recurrence. In the present article, two cases of ameloblastic fibro-odontoma in an unusual region of the maxilla are presented.
El Fibro-odontoma ameloblástico (FOA), es una lesión tumoral mixta de origen odontogénico, el cual tiene un componente epitelial y mesenquimático. En su imagenología se observa como una lesión radiomixta, debido a que algunos autores afirman que este no es más que el predecesor de un odontoma. Epidemiológicamente, se presenta entre la segunda y tercera década de la vida, preferencia por sexo masculino y predilección por el área posterior de la mandíbula. Es una lesión de buen pronóstico que responde bien a la enucleación por curetaje con baja tasa de recidiva. En el presente artículo, se presentan dos casos de fibro-odontoma ameloblástico en una región inusual de los maxilares.

Burkitt's lymphoma, a form of non-hodgkin lymphoma, is a neoplastic monoclonal proliferation of lymphoid cells in areas of the immune system. it can occur in HIV-positive patients, as AIDS is related to the development of non- hodgkin lymphoma. burkitt's lymphoma is a rare subtype, highly prevalent in patients with AIDS. incisional biopsy, in situ hybridization and computerized axial tomography are the appropriate tests to determine the characterize of the lesions. the case of a 4-year-old HIV-positive patient, who developed burkitt's lymphoma of the oral cavity, is reported in this paper. the aim of this case report is to describe the course of the pathology, taking into account its clinical imaging characteristics and treatment.
