The most common bone tumor is a non-ossifying fibroma. [4] Average five-year survival in the United States after being diagnosed with bone and joint cancer is 67%. [5] The earliest known bone tumor was an osteosarcoma in a foot bone discovered in South Africa, between 1.6 and 1.8 million years ago. [6]
Osteochondroma is the most common benign tumor of bone. [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 around the knee and in the forearm.
The following are the most common symptoms of an enchondroma. However, each individual may experience symptoms differently. Symptoms may include: [citation needed] Pain that may occur at the site of the tumor if the tumor is very large, or if the affected bone has weakened causing a fracture of the affected bone; Enlargement of the affected finger
Bizarre parosteal osteochondromatous proliferation (BPOP), also known as Nora's lesion, [4] is a type of non-cancerous bone tumor belonging to the group of cartilage tumors. [1] [2] [5] It is generally seen in the tubular bones of the hands and feet, [6] where it presents with a rapidly enlarging painless lump in a finger or toe.
The tumor is solid, hard, irregular ("fir-tree," "moth-eaten", or "sun-burst" appearance on X-ray examination) due to the tumor spicules of calcified bone radiating at right angles. These right angles form what is known as a Codman triangle , which is characteristic but not diagnostic of osteosarcoma.
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 ...
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 ...
A non-ossifying fibroma (NOF) is a benign bone tumor of the osteoclastic, giant cell-rich tumor type. [1] It generally occurs in the metaphysis of long bones in children and adolescents. [2] Typically, there are no symptoms unless there is a fracture. [2]
