Giant cell tumour 2nd metatarsal—Result with en-bloc excision and autologous fibular grafting

•Giant cell tumour (GCT) of the bone is 3–5% of primary bone tumours.•2nd Metatarsal GCT was excised en-bloc excision and reconstructed using fibular graft.•Differentiate from soft tissue GCT commonly seen at these sites.•Adequacy of tumour removal is influenced by multiple factors.•Orthopaedic tumour surgery should be performed at specialized centres.

Giant cell tumour (GCT) of the small bones is relatively uncommon tumour. It occurs most commonly in the distal portions of femur and radius and proximal end of tibia. GCT of small bones presents at advanced stages with major bony destruction. These tumours represent more aggressive course; associated with increased local recurrence rates (40%) and metastasis. Various treatment modalities like en-bloc resection, cryosurgery, intralesional curettage with burring/phenolization or bone cement are available. In our case en-bloc resection with reconstruction using nonvascular autogenous fibular strut graft was used in patient of 2nd metatarsal GCT and a favourable functional outcome was observed.
