Primary Giant Cell-Rich Lesions of Bone with Role of Denosumab - Histopathological Study with Clinico-Radiological Correlation

Introduction: The diagnosis of primary giant cell-rich lesion of bone is often difficult even for experienced pathologist. The diagnostic histological features are: multinucleated osteoclast-like giant cell and a mononuclear stroma. But sometimes, from the histological picture alone, it is difficult to differentiate between different lesions such as a Giant-cell tumour of bone, Aneurysmal Bone Cyst and Giant-cell Reparative Granuloma. Many of these lesions show some characteristic features such as typical anatomic location and age of the patient, which are also important supporting factor for diagnosis. Hence histopathological study with clinico-radiological correlation is mandatory for precise and accurate diagnosis. These parameters are important for the treatment and prognosis of these lesions.
