Abstract. Malignant bone tumors are either primary or metastatic in nature. The high sensitivity and accuracy of 99m Tc-MDP bone scintigraphy in diagnosing bone metastasis were established as long ago as 1961 (Fleming et al., Radiology 77:635–636, 1961). In contrast, its usefulness in the investigation of primary bone tumors, both malignant and benign, appears not to be fully appreciated.

Bone tumors can either be benign (non-cancerous) or malignant (cancerous). The latter are more prevalent than the former. The two types of tumor manage to grow and put a pressure on a healthy bone

Malignant bone tumors can occur at almost any age. Osteosarcoma and Ewing's sarcoma, two of the most common malignant bone tumors, are usually found in people age 30 or younger. In contrast, chondrosarcoma, malignant tumors that grow as cartilage-like tissue, usually occur after the age of 30. Malignant bone tumors … Multiple myeloma is the most common primary bone cancer. It is a malignant tumor of bone marrow—the soft tissue in the center of many bones that produces blood cells. Any bone can be affected by this cancer. Multiple myeloma affects approximately seven people per 100,000 each year.

Cartilage and bone formation characterize these tumors and bone destruction is Primary bone cancer is a rare type of cancer that begins in the bones. surgery to remove the section of cancerous bone – it's often possible to reconstruct or This study compares the ability of 201TIand 99mTc-MIBI to detect and assess tumor response to chemotherapy in malignant and benign bone and soft-tissue The next type of bone tumors are Malignant Bone Tumors.

The functional and oncologic results of eighteen patients with primary malignant periacetabular tumors were reviewed to determine the impact of surgical treatment. The reconstruction procedures were endoprosthesis (11), hip transposition (4), iliofemoral arthrodesis (2), and frozen bone autograft (1). After a mean follow-up of 62 months, 13 patients were alive and 5 had died of their disease Technetium bone scintigraphy can be helpful in reveal-ing an osseous lesion and to document multifocality [3].

The vast majority of these tumors are squamous cell carcinomas and their treatment is eminently surgical. Osteosarcoma is a primitive malignant bone tumor characterized by the production of osteoid or immature bone from neoplastic cells [ 4 ].

A sarcoma is a type of tumor that develops in connective tissue, such as bone, cartilage or muscle. Malignant sarcoma are very rare (1% of all adult malignancies and about 15% of childhood malignancies). Primary Malignant Bone Tumors Multiple myeloma.
