Giant-cell tumor of bone - Wikipedi

  1. Giant-cell tumor of the bone ( GCTOB ), is a relatively uncommon tumor of the bone. It is characterized by the presence of multinucleated giant cells ( osteoclast -like cells). Malignancy in giant-cell tumor is uncommon and occurs in about 2% of all cases. However, if malignant degeneration does occur, it is likely to metastasize to the lungs
  2. A giant cell tumor of bone is a type of benign (noncancerous) tumor that grows at the ends of the body's long bones. Most often, the tumors develop at the lower end of the femur (thighbone) or upper end of the tibia (shinbone), close to the knee joint. Giant cell tumors typically occur in young adults, and are slightly more common in females
  3. Giant cell tumor of soft parts, also referred to as giant cell tumor of soft parts of low malignant potential, typically manifests as multinodular masses in the skin or subcutis of young to middle-aged adults, although occasional cases may manifest as more deeply seated masses or in children
  4. Giant cell tumor of bone. Giant cell tumors of bone , also known as osteoclastomas , are relatively common bone tumors and are usually benign. They typically arise from the metaphysis of long bones, extend into the epiphysis adjacent to the joint surface, and have a narrow zone of transition
  5. Tenosynovial giant cell tumors are benign (not dangerous), slow-growing tumors that affect joints in the fingers, hands, arms, shoulders, or legs. These tumors are relativity common, particularly in the hands and fingers. They are also called giant cell tumors of the tendon sheath or fibrous histiocytoma of the tendon sheath. 1
  6. a Giant Cell Tumors (GCT) is a benign aggressive tumor typically found in the metaphysis of long bones, often around the knee, in young adults. treatment is generally curretage, adjuvant treatment, and reconstruction as necessary depending on location of lesion. Epidemiology

  1. A giant cell tumor is a rare, aggressive non-cancerous tumor. It usually grows near a joint at the end of the bone. Most occur in the long bones of the legs and arms. Giant cell tumors most often occur in young adults when skeletal bone growth is complete
  2. A giant cell tumor is a rare, abnormal growth of tissue which generally forms around the end of a long bone, most commonly the knee. The tumor is called giant because it looks very large under a microscope, and is made up of cells with more than one nucleus.Most of these are benign, though in rare cases they can be cancerous

  4. A giant cell tumor (GCT) of bone is a benign (noncancerous) bone tumor that typically develops near the joints of the knee, wrist, shoulder, or spine. At The Spine Hospital at The Neurological Institute of New York, we specialize in giant cell tumors of the spine. The spine is composed of bones called vertebrae
  5. Tenosynovial giant cell tumor is a group of rare, typically non-malignant tumors of the joints. TGCT tumors often develop from the lining of joints. Common symptoms of TGCT include swelling, pain, stiffness and reduced mobility in the affected joint or limb. This group of tumors can be divided into different subsets according to their site, growth pattern, and prognosis. Localized TGCT is sometimes referred to as giant cell tumor of the tendon sheath; diffuse TGCT is also called pigmented villo
  6. Background: Denosumab is a human monoclonal antibody (mAb) that specifically inhibits tumor-associated bone lysis through the RANKL pathway and has been used as neoadjuvant therapy for giant-cell tumor of bone (GCTB) in surgical as well as non-surgical cases. The purpose of this systematic review of the literature, therefore, is to investigate: (1) demographic characteristics of patients.
  7. Giant cell tumours (GCT) are benign (non-cancerous) tumours that develop in the bone. They mostly occur in the long bones found in the arms and legs. They are always found at the end of the bone next to the joint. Although they are benign, GCT can grow fast and damage the affected bone and spread to the soft tissue around it

What is a Giant cell tumor of bone. Giant cell tumor is a locally aggressive neoplasm of uncertain origin which affects predominantly the epiphysis of long bones.
