[Giant cell tumors of maxilla].

Ten cases of giant cell tumor of maxilla are reported, the patients being children or young adults and of principally female sex. In three cases another affection was associated: Recklinghausen's disease, Francescatti syndrome and hyperthyroidism of adenomatous origin. Histology of all tumors was similar: giant cells, fibroblastic tissue and numerous vessels: the course was benign in all cases with frequent recurrences but no metastases. The pathology of these tumors is still the subject of wide debate, although research is extensive in this field: electron microscopy, histoenzymology, monoclonal antibodies are some aspects studied but results have sofar failed to elucidate the true nature and histoprognosis of these tumors.
