Tenosynovial giant cell tumor (TGCT) is a non-malignant tumor defined histologically as inclusions of “osteoclast-like” multinucleated giant cells, hemosiderin, and macrophages. [1] This histology can present one of 2 clinically distinct ways. TGCT tumors often develop from the lining of joints (also known as synovial tissue).
When a person has primary bone cancer, the cancer cells are bone cells that have become cancerous. According to the NHS , around 550 cases of primary bone cancer are diagnosed each year in the UK.
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]
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]
An osteoid osteoma is a benign (non-cancerous) bone tumor that arises from osteoblasts and some components of osteoclasts. It was originally thought to be a smaller version of an osteoblastoma. Osteoid osteomas tend to be less than 1.5 cm in size. The tumor can be in any bone in the body but are most common in long bones, such as the femur and ...
Ewing sarcoma is a type of pediatric cancer [5] that forms in bone or soft tissue. [1] Symptoms may include swelling and pain at the site of the tumor, fever, and a bone fracture. [2] The most common areas where it begins are the legs, pelvis, and chest wall. [4]
X-ray of a giant-cell bone tumor in the head of the fourth metacarpal of the left hand. On X-ray, giant-cell tumors (GCTs) are lytic/lucent lesions that have an epiphyseal location and grow to the articular surface of the involved bone. [8] Radiologically the tumors may show characteristic 'soap bubble' appearance. [9]
The tumor may be localized at the end of the long bone (commonly in the metaphysis). Most often it affects the proximal end of tibia or humerus , or distal end of femur . Osteosarcoma tends to affect regions around the knee in 60% of cases, 15% around the hip , 10% at the shoulder , and 8% in the jaw .
