Central giant cell granuloma (CGCG) is an intra-osseous lesion consisting of cellular fibrosis tissue containing multiple foci of hemorrhage, multinucleated giant cells and trabecules of woven bone.1 This lesion accounts for less than 7% of all benign jaw tumours.2 Jaffe3 considered it as a locally reparative reaction of bone, which can be possibly due to either an inflammatory response, hemorrhage or local trauma. Females are affected more frequently than males. It occurs over a wide age range.4 It has been reported that this lesion is diagnosed during the first two decades of life in approximately 48% of cases, and 60% of cases are evident before the age of 30. It is considerably more common in the mandible than in the maxilla. Most lesions occur in the molar and premolar area, some of these extending up to the ascending ramus.
The presence of giant cell granuloma in the mandibular body area, the entire ramus, condyle and coronoid represents a therapeutic challenge for the oral and maxillofacial surgeons. The aim of this report is to describe an unusual presentation of central giant cell granuloma involving the mandibular body, ramus, condylar and coronoid processes, and to discuss the differentiated diagnosis, the radiographic presentation and the management of this lesion.
