BONE TUMOURS
It can be daunting when faced with a bone lesion as the list of possible diagnoses is long.
Simple bone cyst   Aneurysmal bone cyst   Chondroma   Osteochondroma   Osteoblastoma   Osteoid osteoma   Chondroblastoma   Periosteal chondroma   Eosinophilic granuloma   Non ossifying fibroma   Brown tumor   Chondromyxoid fibroma   Giant cell tumour   Fibrous Histiocytoma   Fibrous dysplasia   Osteoma   Haemangioma   Giant cell reparative granuloma   Desmoplastic fibroma   Ganglion   PNET   Adamantinoma   Hemangioendothelioma   Osteosarcoma   Ewings PNET   Chondrosarcoma   Fibrosarcoma   MM/Plasmacytoma   Lymphoma   Angiosarcoma
Fortunately, primary bone tumours tend to follow certain patterns and these can be used to narrow down the list
      • Which bone is involved
      • How old is the patient
      • What are the characteristics of the lesion
The principal characteristics are: location within the bone, lytic or sclerotic, well or poorly defined and so forth
So begin by selecting the Which Bone? tab oposite, then explore the characteristics of the most common lesions to see if it fits with your case
Remember also that there are lesions that mimic primary bone tumours, so also explore the lists of multifocal lesions
