Advanced giant cell reparative granuloma of the mandible: radiological features and surgical treatment.

Giant cell reparative granuloma accounts for 1%-7% of all benign lesions of the jaw. Giant cell reparative granuloma often arises in the mandible and in the maxilla and affects children and young adults. It is usually a slow-growing lesion, fast-growing lesions having rarely been reported. The latter, despite the innocent histological appearance, has an aggressive behaviour mimicking a malignant lesion. In the present report the clinical features of an aggressive variety of giant cell reparative granuloma in a 21-year-old female are described focusing on the dental findings at computed tomography and surgical treatment.
