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 ...
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.
Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis.Other indications include rheumatoid arthritis, avascular necrosis, traumatic arthritis, protrusio acetabuli, [5] certain hip fractures, benign and malignant bone tumors, [6] arthritis associated with Paget's disease, [7] ankylosing spondylitis [8] and juvenile rheumatoid arthritis.

Magnetic resonance imaging slice showing Ewing sarcoma of the left hip (white area shown right) Magnetic resonance imaging (MRI) should be routinely used in the work-up of malignant tumors. It will show the full bony and soft tissue extent and relate the tumor to other nearby anatomic structures (e.g. vessels).
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]
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]
SEF tumors often occur in a shoulder, hip, or lower areas of the legs and arms or, less commonly, in a vital organ or other tissue location that may be in virtually any part of the body. [7] SEF tumors tend to recur at the site where they are surgically removed, to metastasize to other tissues, and to have poor outcomes. [7]
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.
