Giant cell tumour (GCT) is histopathologically benign tumor of long bone particularly in distal femur and the
proximal tibia. It commonly occurs in adults of age 20-40 years but rare in children. GCT is considered to be locally
aggressive tumor and tendency of recurrence is higher even after surgery.
The clinical features are nonspecific, the principle symptoms are pain, swelling and limiting adjacent joint
movements. Diagnosis is based on the radiographic appearance and histopathological findings .In our case X-ray
showed ill defined lytic lesion on proximal fibula with cortical thinning and MRI finding revealed expansile lytic
lesion in meta-epiphysis of right fibula 16×16×28mm adjacent to growth plate with fluid level. The sclerotic rim
appears hypointense on T1 & hyperintense on T2. Core needle biopsy showed giant cell tumor on proximal fibula.
Considering the risk of recurrence wide local excision was done. Management of GCT of proximal fibula in young
patient is critical for preventing recurrence and enhancing functional outcomes by saving adjacent anatomical
structure. No evidence of local recurrence and metastasis was found in 24 months of follow up.
