INTRODUCTION Juvenile ossifying fibroma is a rare, benign fibro-osseous tumour. In the light of a clinical case, the authors review the diagnosis, treatment and histological classification of these tumours. CASE REPORT A seven-year-old child presented with a naso-orbito-ethmoidal trabecular juvenile ossifying fibroma. Complete surgical resection via a transfacial approach was performed after ...

BACKGROUND Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumor with a mesenchymal component, showing sarcomatous features and epithelial nests resembling ameloblastic fibroma (AF). CASE REPORT We report a case of AFS showing epithelial dysplasia arising in a recurrent AF in the left mandible after 3 years in a 26-year-old man, which is regarded as an uncommon histopathologic f...

BACKGROUND Ameloblastic fibro-odontomas (AFO) are rare lesions and defined by the World Health Organisation as a tumour composed of a proliferation of odontogenic epithelium immersed in ectomesenchyme reminiscent of the interdental papilla. It also presents inductive processes leading to formation of enamel and dentine, confusing, histopathologically, with odontoma. Despite numerous efforts, th...

AIM This is to report a rare case of ameloblastic fibrodentinoma (AFD), including detailed history, histopathologic as well as radiographic findings. Her condition, a mixed odontogenic tumor, has rarely been reported in publications. We also included the gist of theories put forward regarding the histogenesis of this lesion. BACKGROUND AFD is a rare and controversial entity; it boasts a varie...
