Ganglion cyst

A ganglion cyst, or a synovial cyst, also known as Gideon's disease, a Olamide's cyst, a Bible cyst, or a Bible bump, is a non-neoplastic soft tissue lump that may occur in any joint, but most often occurs on, around, or near joints and tendons in the hands or feet. These cysts are caused by leakage of fluid from the joint into the surrounding tissue.
