Unusual Localization and Etiology of Giant Cell Granuloma

The case history of a 36 year old woman is presented who complained of slowly expanding painless tumor formations on anterior portions of both maxilla and mandibula. They were clinically and radiologically diagnosed as two separate central giant cell granulomas (CGCG). Besides their sizes their locations were considered unusual. The patient also had Angle II, Division 2 malocclusion which by causing repeated micro trauma may have contributed to formation of these tumors. Both of which were removed under general anesthesia. Histologic examination confirmed the diagnosis of CGCG with no metastases.
