Abstract

Introduction: Giant cell lesions of orofacial region although rare in presentation, have diagnostic and treatment challenges due to overlapping clinical, radiological, and histopathological signs.

Background: We happened to come across a case, which presented to us with an aggressive jaw lesion of nonodontogenic origin, mimicking a malignancy and putting us in a conundrum with regard to work up and treatment. The sequential work up not only helped us reach a definitive diagnosis but also led us the draw algorithms for diagnosis of Giant cell lesions and management of Central giant cell granuloma.

Conclusion: Meticulous planning along with molecular studies helps in better delineating one giant cell lesion from other.

Keywords: Brown tumour; Central giant cell granuloma; Giant cell lesions; Giant cell tumour; Oral cavity.
