  2. Bone tumor - Wikipedia

    en.wikipedia.org/wiki/Bone_tumor

    A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]

  3. Osteosarcoma - Wikipedia

    en.wikipedia.org/wiki/Osteosarcoma

    An osteosarcoma (OS) or osteogenic sarcoma (OGS) (or simply bone cancer) is a cancerous tumor in a bone.Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid.

  4. Bone metastasis - Wikipedia

    en.wikipedia.org/wiki/Bone_metastasis

    Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma, chondrosarcoma, and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [1] Bone metastases can be classified as osteolytic, osteoblastic ...

  5. Ewing sarcoma - Wikipedia

    en.wikipedia.org/wiki/Ewing_sarcoma

    Bone scintigraphy can also be used to follow tumor response to therapy. [27] In the group of malignant small round cell tumors that includes Ewing sarcoma, bone lymphoma, and small cell osteosarcoma, the cortex may appear almost normal radiographically, while permeative growth occurs throughout the Haversian channels.

  6. Chondrosarcoma - Wikipedia

    en.wikipedia.org/wiki/Chondrosarcoma

    Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. [2] It is resistant to chemotherapy and radiotherapy. Unlike other primary ...

  7. Osteochondroma - Wikipedia

    en.wikipedia.org/wiki/Osteochondroma

    [1] [2] The tumors take the form of cartilage-capped bony projections or outgrowth on the surface of bones . [3] [4] It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone. Tumors most commonly affect long bones about the knee and in the forearm.

  8. Giant-cell tumor of bone - Wikipedia

    en.wikipedia.org/wiki/Giant-cell_tumor_of_bone

    X-ray of a giant-cell bone tumor in the head of the fourth metacarpal of the left hand. On X-ray, giant-cell tumors (GCTs) are lytic/lucent lesions that have an epiphyseal location and grow to the articular surface of the involved bone. [8] Radiologically the tumors may show characteristic 'soap bubble' appearance. [9]

  9. Osteoblastoma - Wikipedia

    en.wikipedia.org/wiki/Osteoblastoma

    Osteoblastoma is an uncommon osteoid tissue-forming [1] primary neoplasm of the bone. It has clinical and histologic manifestations similar to those of osteoid osteoma; therefore, some consider the two tumors to be variants of the same disease, [2] with osteoblastoma representing a giant osteoid osteoma. However, an aggressive type of ...
