Radiographically, the lesion shown in color plate could be:
Osteosarcoma
Fibrous dysplasia
Garre's osteomyelitis
Cherubism
Formation of layers of new subperiosteal bone produces onion skin appearance which is seen in Garre's osteomyelitis, Ewing’s Sarcoma and Chondrosarcoma.
In fibrous dysplasia, "ground glass" or "peau d’orange" appearance is seen radiologically.
