Giant Cell Lesions of the Jaws: A Work on Current Concepts and Making Through a Working Classification.

INTRODUCTION

Giant cell-rich lesions are a diverse group of lesions that usually occur in bone and contain varying numbers of reactive osteoclastic-type multinucleate giant cells. These lesions present a challenge in pathologic diagnosis, often requiring a combination of clinical, radiographic, and histopathological assessments. The present retrospective observational study aims to provide a concise diagnostic criterion by combining all these parameters, which will aid in effective diagnosis and targeted treatment planning in the future.

MATERIAL AND METHOD

Previously diagnosed cases of these lesions were taken from the archives and categorized as Central Giant Cell Granuloma (CGCG), CGCG with secondary Aneurysmal Bone Cyst (ABC), primary ABC, and Brown's Tumour. Their demographic characteristics along with clinical, radiological, and histological data were retrieved and compiled into the table. The data was then analyzed and classified into aggressive and non-aggressive CGCG according to the criteria set in the study.

RESULT

10 reported cases were of isolated CGCG, 5 were CGCG with secondary ABC, 5 of Brown's tumor and 3 were that of conventional ABC. Out of these, the lesions showing extensive size along with an increased number of giant cells were categorized under aggressive CGCG, whereas those with less aggressive characteristics were categorized under non-aggressive CGCG. The aggressive category comprised 5 cases of isolated CGCG, 2 cases of CGCG with secondary ABC, 3 cases of primary ABC, and 5 of brown tumor, whilst the rest of the cases were categorized under non-aggressive CGCG.

CONCLUSION

Since all these share overlapping features, thereby this type of concise categorization is the dire need so that the lesions can have a precise diagnosis with treatment and follow-up intervals for aggressive lesions.
