Giant Cell Tumor in the Proximal Femur of an Eight-Year-Old Boy: A Case Report

Giant cell tumor (GCT) is a benign aggressive bone tumor that occurs mostly in young adult patients after puberty. The most common location is around the knee joint. Occurrence in pre-puberty pediatric patients is very rare and accounts for 1.8% to 10% of all known GCTs.

Case Report: 

Here, we report an eight-year-old boy who complained of pain and loss of range of motion (ROM) in the right hip. Radiological and pathological studies revealed GCT of the femoral head with joint expansion. We treated the patient by wide resection and osteochondral allograft reconstruction.

We believe this is the first reported case of GCT in the proximal femoral bone of pediatric patients, which is proven by pathology. Studying the current case may help tumor surgeons to become aware of this possibility.
