Giant Cell Tumour of the Patella: A Missing Differential Diagnosis in the Young

Herein, we discuss the case of a 26-year-old male patient with a diagnosis of giant cell tumour (GCT) of the patella which is an exceptionally uncommon condition. The motive of reporting a rare case such as the giant cell tumour of the bone (GCTB) relies on its diagnostic incidence. Since the symptoms of this tumour overlap more common etiologies than GCT, the diagnosis of such a devastating malignant tumour is usually missed and hence delayed, which leads to poor treatment strategies and ultimately an irreversible fatal outcome.
