title: Recurring giant-cell granuloma at the site of previous radiation therapy.
abstract: A 15-year-old girl presented with an aggressive giant-cell granuloma (GCG) of the maxilla with local invasiveness and bony destruction. The tumor recurred twice and attained a diameter of 6 cm. Previously, this patient had had two hematologic malignancies for which she had received therapeutic doses of radiation to the site where the GCG occurred. It is therefore possible that this tumor was radiation induced.
