Synovial chondroma symptoms?
summary
Synovial osteochondroma is also called primary synovial chondromatosis, synovial osteochondromatosis and synovial chondrogenic metaplasia. There are statistical reports that synovial tumors or tumor like lesions account for 6.7% - 22.6%, the age of onset can be from childhood to 80 years old, the ratio of male to female is 2:1. Often involving a joint. About 2 / 3 of the cases occurred in knee joint, followed by hip joint, elbow joint and shoulder joint. Most people think that synovial osteochondroma is a kind of reactive metaplasia of joint synovium with unknown etiology, because the disease is self limited, and a few cases can subside spontaneously. Synovial chondroma symptoms? Let's talk about it
Synovial chondroma symptoms?
The main manifestations were joint pain, joint swelling and limited movement, occasionally touching the free body. Often appear joint interlocking, joint swelling can gradually aggravate, sometimes joint effusion can appear. The course of disease is generally long, and the development is slow, which can last for months to years.
On the synovial surface, there were several to hundreds of bony nodules, up to thousands, ranging in size from 1-2mm to several centimeters, with smooth, shiny and blue white surface.
In the early stage of histopathology, round cellular cartilage island was formed in the connective tissue of the joint capsule, which was located in the subcutaneous synovium and was a well-defined non-invasive growth nodule. The nodule could be completely composed of cartilage. Chondrocytes were clustered and disorderly arranged, with mast cell nuclei and moderate degree of nuclear pleomorphism. Binuclear cells were common.
matters needing attention
The principle of treatment is to remove the free body and synovium thoroughly. Some people advocate that the free body should be completely removed, only the synovium of the lesion should be removed, and it is not required to completely remove the synovium. If synovial osteochondroma is found to be normal in the book without synovectomy, these free bodies may come from joint lesions.
