[Adamantinoma of the long bones: an anatomo-clinical review and its relationship with osteofibrous dysplasia].

Adamantinoma of long bones is a perplexing tumor for its histology as well as for its histogenesis. Recent progress has been made with ultrastructural and immunohistochemical works. The possible relationship with osteofibrous dysplasia is the subject of conflicting discussions and the potential link has implications for the diagnosis, prognosis, and treatment. Clinical aspects of adamantinomas are described: location, age, gender, symptoms, imaging, diagnosis, treatment, clinical course, prognosis. Histopathology is extensively covered for usual and peculiar forms. Immunohistochemical results are described and discussed. Data of electron microscopy, cytological findings, and DNA flow cytometry are also reported. The putative association with osteofibrous dysplasia is the subject of an extensive development with the report of the personal experience and works of the authors, and arguments for viewing osteofibrous dysplasia and "osteofibrous dysplasia-like" adamantinomas as precursor lesions of classic adamantinomas are favoured.
