[Giant cell tumors and pseudogiant cell tumors of the jaws].
Giant cell tumors and pseudogiant cell tumors of the jaws are divided into cherubism, central giant cell granuloma (CGCG), aneurysmal cyst, giant cell tumor, and hyperparathyroidism-jaw tumor. These tumors have variable clinical characteristics, such as bilateral tumors in cherubism, disseminated tumors in hyperparathyroidism, or focal tumors in other types. Their radiological presentation is quite similar with presence of well-delimitated uni- or multilocular radiolucency. The primary surgical treatment must be conservative. Anatomopathology gives the histologic diagnosis, with presence of giant cells. Some tumors are locally aggressive leading to larger bone exeresis. The nosology of these giant-cell tumors remains unclear, especially for giant cell central granuloma and giant cell tumors.
