title: Giant cell tumour of a temporomandibular joint presenting as a parotid mass: case report and analysis of the 19 cases in the literature.
abstract: Giant cell tumour (GCT) in the parotid region is a rare lesion whose origin can be divided into three compartments: giant cell tumour of the salivary gland (GCT-SG), giant cell tumour of the bone (GCT-bone) and giant cell tumour of the soft tissue (GCT-ST). A low risk of malignancy has been observed, in which all of them were GCT-SG. We present a case of GCT in the parotid region and review the features of GCT in origin, immunohistochemical characteristics, treatment of choice and disease outcome.
