En block resection of GCT at proximal fibula in skeletally immature individual presented with neuropraxia: A case report with literature review

Introduction: proximal fibula is a rare site for giant cell tumor and very few cases are reported in skeletally immature individual. Controversies are present for the management of tumor at this site. 16 year old boy presented with swelling in left proximal fibular region with foot drop. Needle biopsy revealed giant cell tumor. Type I en bloc resection was performed and followed up for 12 months. Currently he has no signs of recurrence and infection and he is back to his routine work and is in regular follow up. GCT is a tumor of skeletally mature individuals and proximal fibula is a rare site. It is rare to find in skeletally immature individual. Controversies regarding peroneal nerve sparing and reattachment of lateral stabilizers is still present. There is good outcome of malawer type 1 en bloc resection in cases of benign locally aggressive tumor if done carefully and from our point of view, peroneal nerve should be preserved for better outcomes.
