Introduction: Giant cell tumour is a locally aggressive tumour. Most common age group affected is 20 to 55 years. It is more common among females. Most common sites are the distal end of radius and the proximal tibia. 5% of primary bone tumours represents giant cell tumour.

Case Report: A 22-year-old male patient presented with complaints of pain of the right ankle joint for 2 months. There was no history of trauma. On examination, tenderness on the anterolateral aspect of the right ankle joint was elicited. No visible swelling was found and there was no restriction of movements. X-ray of right ankle joint showed a lytic lesion in the distal epi-metaphyseal region of the tibia. Magnetic resonance imaging revealed a lesion at distal epi-metaphyseal end of tibia. It was an expansile lesion causing cortical destruction with possibility of GCT.  Excision and curettage of tumour with bone grafting was performed to fill the defect. Histopathological examination of the tissue showed multinucleated giant cells with a uniform vesicular nucleus and the spindle shaped mononuclear cells with uniform vesicular nucleus suggestive of GCT.

Conclusion:  We did 7 months of out-patient follow-up. Patient had full range of motion of the ankle joint during follow up. There are no signs of recurrence till now.
