Metachronous multicentric giant cell tumour of bone.

Metachronous multicentric giant cell tumour (GCT) of bone is rare. We report a case of a 21-year-old man with metachronous multicentric GCTs, with five (including one recurrence) documented lesions reported over a span of 9 years involving various sites, which included the fifth metacarpal bone of the right hand, the intermediate cuneiform bone of the right foot, the left proximal humerus and the lateral malleolus of the right tibia. The radiological appearance of these lesions in these various sites with correlation among clinical history, histopathology and the treatment approach is described in this report. He is undergoing regular follow-up and has now once again presented with recurrence of the right tibial lesion. The case is reported for its rarity.
