A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones. [1] Synchondroses are different from symphyses (secondary cartilaginous joints), which are formed of fibrocartilage , and from synostosis (ossified junctions), which is the fusion of two or more bones.
Synovial osteochondromatosis (SOC) (synonyms include synovial chondromatosis, primary synovial chondromatosis, synovial chondrometaplasia) is a rare disease that creates a benign change or proliferation in the synovium or joint-lining tissue, which changes to form bone-forming cartilage.
The diagnosis is confirmed when the patient reports a significant change in relief from pain and the diagnostic injection is performed on 2 separate visits. Published studies have used at least a 75 percent change in relief of pain before a response is considered positive and the sacroiliac joint deemed the source of pain. [15] [16] [17]
These nodules eventually break free and float around the joint space becoming larger – these add to the discomfort and stiffness of the joint. The affected tissue will show up as a semi-solid mass in an MRI scan, final diagnosis is usually confirmed by taking a biopsy.
The International Childhood Cancer Day: a global campaign to promote awareness of childhood cancer and express support to children with cancer, and their families.

[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] A bone tumor might present with a pathologic fracture. [1] Other symptoms may include fatigue, fever, weight loss, anemia and ...
A malignant peripheral nerve sheath tumor (MPNST) is a form of cancer of the connective tissue surrounding peripheral nerves. Given its origin and behavior it is classified as a sarcoma. About half the cases are diagnosed in people with neurofibromatosis; the lifetime risk for an MPNST in patients with neurofibromatosis type 1 is 8–13%. [2]
Children whose cranial plates fuse too early may suffer deformities and brain damage as the skull does not expand properly to accommodate the growing brain, a condition known as craniosynostosis. Synchondrosis is a cartilaginous joint connected by hyaline cartilage , as seen in the epiphyseal plate .
