The Giant Cell Tumor of 1st Metatarsal in a Young Adult: A Rare Versatile Management with Fibula Cortical Graft.

Introduction: Giant cell tumor is a benign aggressive tumor commonly affecting the 2nd decade. Most commonly seen in the ends of long bones like the distal femur, proximal tibia, distal radius, and proximal humerus, but it does occur in small bones like hands and feet in <2%.

Case report: A young female adult of age 23 has been diagnosed with a giant cell tumor of her 1st metatarsal and underwent complete excision with reconstruction with non-vascularized autogenous cortical fibula strut graft using a reconstruction plate and screws and 1-year follow-up showed a good graft union and no signs of recurrence.

Conclusion: Local resection of the affected metatarsal combined with chemoablation reduces recurrence risk, while a fibula graft offers structural stability. In our case, there were no signs of recurrence, and the graft showed good incorporation.
