    Pathology - General

    Bone tumours can be subdivided into benign and malignant lesions. The malignant lesions can be further subdivided into primary bone tumours, secondary bone tumours (malignant transformation in a pre-existing lesion) and bone metastases. Of these, the primary malignant bone tumours are the most rare, accounting for approximately 0.2% of all malignant tumours in the body. The most common primary malignant bone tumours are osteosarcoma (35%), chondrosarcoma (26%), and Ewing sarcoma (16%). NB: multiple myeloma and lymphoma are not included in these figures, since they are regarded as malignancies of lymphohematopoietic origin, rather than primary bone tumours.

    The figure below provides a brief overview of the most common primary bone tumours.
