Abstract
Giant cell lesions are characterized by the presence of multinuclear cells, and those known to develop in the jaws include the giant cell granuloma, the giant cell tumor, the brown tumor of hyperparathyroidism, cherubism, and others. In those diseases, brown tumor occurs rarely in the jaws.
Histologic differentiation between brown tumor and giant cell granuloma may be impossible: as a result, biochemical abnormalities associated with hyperparathyroidism may have to be evaluated.
A case of brown tumor of the right maxilla in primary hyperparathyroidism is reported in this pater. A-44-year-old woman was referred to our clinic with the chief complaint of a painless swelling of the right hard palate.
X-ray CT revealed a well defined rounded mass for disclosing in the right maxillary anturum, although the lesion appeared as a diffuse radio-opaque area on roentgenographic examinations.
The lesion was biopsied and diagnosed as brown tumor. The surgical exicision of the lesion was performed by intraoral approach under general anesthesia.
The clinical course was uneventful after surgery. Eleven months postoperatively, there is no evidence of recurrence.
