Synchronous central giant cell granuloma and ossifying fibroma of the mandible

Abstract

Central giant cell granuloma (CGCG) is a benign lesion of the jaws. In most cases, the lesion presents as a painless, slow-growing swelling of the jaws. Ossifying fibroma (OF) of the jaw is a benign neoplasm that consists of variable amounts of mineralized material embedded in a fibrous stroma. The simultaneous occurrence of CGCG with odontogenic fibroma or OF has been described as combined lesions. However, synchronous presentation of CGCG and OF in the mandible is a rare occurrence. This report describes a case of 2 completely independent CGCG and OF located on both posterior regions of the mandible.
