Ossifying fibroma is benign, uncommon, monostotic well defined usually unilocular but occasionally multilocular fibroosseous tumor, arising from the cells of periodontal ligament and is composed of fibrous connective tissue with variable amounts of calcified tissue resembling bone, cementum or both. It is generally an asymptomatic, slow growing lesion, found in 2nd to 4th decades of life at the...

The aim of this paper was to present a brief case report of Trabecular Juvenile Ossifying Fibroma (WHO-type) (TJOF WHO-type), and compare the clinical and histopathological findings with current literature in order to seek clarification of the nature and behavior of the lesion. Conclusions: The TJOF (WHO-type) is a rare fibro-osseous begnin injury with biologic aggressive behavior, and unknown ...

BACKGROUND Fibrous dysplasia, ossifying fibroma, and desmoplastic fibroma are rare benign calvarial lesions, which can have local aggressive behavior. These tumors can present with similar clinical and radiologic characteristics making diagnosis difficult at times. CASE DESCRIPTION A 16-year-old male presents after noting an indentation of his skull. Comparison with current and previous imagi...

During osteogenesis, mesenchymal tissues function to form fibrous matrix which changes into bone by ossification. In rare instances, fibrous matrix persists in which foci of immature bone is evident resulting in progressive enlargement. Such conditions are commonly benign in nature but few are anatomically benign and clinically destructive. Though recurrence and residual defects following surgi...
