Central giant-cell granuloma (CGCG) is a benign condition of the jaws. It is twice as likely to affect women and is more likely to occur in 20- to 40-year-old people. Central giant-cell granulomas are more common in the mandible and often cross the midline. == Overview == CGCG lesions are found more commonly in the anterior of the maxilla and the mandible in younger people (before age 20). They are characterized by large lesions that expand the cortical plate and can resorb roots and move teeth. They are composed of multi-nucleated giant cells. CGCG has a slight predilection for females. Radiographically it appears as multilocular radiolucencies of bone. There are two types of CGCG's, non-aggressive and aggressive. The former has a slow rate of growth and thus less likely to resorb roots and perforate the cortical plate. The aggressive form has rapid growth and thus is much more likely to resorb roots and perforate the cortical plate. It also has a high rate for recurrence and can be painful and cause paresthesia. Differential diagnosis to include: odontogenic keratocyst (OKC), ameloblastoma, odontogenic myxoma, hemangioma, central odontogenic fibroma, hyperparathyroid tumor, and cherubism. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Central giant-cell granuloma」の詳細全文を読む スポンサード リンク
