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).
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]
Signs and symptoms are classified into three groups based on the affected functions of the frontal and temporal lobes: [8] These are behavioural variant frontotemporal dementia, semantic dementia, and progressive nonfluent aphasia.

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.
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]
Researchers examined all studies between 1984 and 2024 which reported on survival or nursing home admission for people with dementia. A total of 235 studies reported on survival among more than 5. ...
“Stop scaring people to think that once they get a diagnosis of some kind of neurocognitive disease that ‘That’s it. It’s over. Let’s pack it up. Nothing else to see here, we’re done ...
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 ...
