Abstract

The central giant cell granuloma(CGCG) of bone constitutes about 10% of benign jawbone lesions. It affects females more often than males, mandible than maxilla. Biological behavior of CGCG ranges from a slow growing asymptomatic swelling to an aggressive process. True giant cell tumor (GCT) should be distinguished from CGCG. The histological distinction between these lesions depends on quite subtle differences. Expression of p63 has been demonstrated in GCT of bone conversely, has not been detected in CGCG. Therefore this short study attempts to study the expression of p63 in CGCG in conjunction with clinicopathological profile of the cases reported in the institute. To review all the cases of CGCGs of the jaws reported in the institute from 1998 to 2015 and study their clinicopathological profile.To study the immunohistochemical (IHC) expression of p63 in CGCG cases. The retrospective study reviewed records for clinically and histopathologically diagnosed cases of CGCG from the archives of department of Oral pathology. Data was recorded and analyzed. These cases were subjected for IHC analysis for expression of p63, also RANK, RANKL in selected cases to study the nature of giant cells. This paper is an institutional experience...Continue Reading
