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]
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.
Ewing’s sarcoma of bone is the most common of the EFTs and tends to occur in the trunk and long bones. The cancer most often occurs in the shaft, or diaphysis, of bones, as compared to other common bone cancers. The most common presenting symptom is pain in the bone, and the initial diagnostic step is imaging, often both MRI and radiograph.
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.
Enchondroma is a type of benign bone tumor belonging to the group of cartilage tumors. [1] [2] There may be no symptoms, [3] or it may present typically in the short tubular bones of the hands with a swelling, pain or pathological fracture.
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 ]
