Ganglion Cyst
Wikipedia: The exact cause of the formation of ganglion cysts is still unknown. They are believed to be caused by overuse of a specific joint, which results in the degeneration of the surrounding fibrous tissue and the development of a cystic structure. The cyst contains clear fluid similar to synovial fluid. They are most often found around the wrist joint, especially at the scapho-lunate joint, which accounts for 80% of all ganglion cysts.
