Giant cell tumor-Giant cell tumor is a lesion with multinucleated giant cells.
-In most cases it is a benign lesion.
-Malignant GCT is rare and differentiation between benign or malignant GCT is not possible based on the radiographs.
-GCT is also included in the differential diagnosis of an ill-defined osteolytic lesion, provided the age and the site of the lesion are compatible.
-Discriminators:
Epiphyses must be closed.
Must be an epiphyseal lesion and abut the articular surface.
Must be well-defined and non-sclerotic margin. Must be eccentric.
