AB Ganglion  (synovial)  cysts  are  a  cystic  swelling  overlying  a  joint  or  tendon  sheath.  They  are  the  most  common  soft-tissue  tumors  of  the  hand  and  wrist,  although  they  can  arise  over  any  joint.  The  etiology  is  currently  debated;  the  most  commonly  accepted  theory  is  the  cyst  forms  secondary  to  mucoid  degeneration  of  collagen  and  connective  tissues.  It  is  unclear  whether  repetitive  motion  leads  to  causation,  although  it  does  appear  to  provoke  symptoms  and  possibly  lead  to  cyst  enlargement.  They  may  occur  in  any  age,  although  the  majority  arise  between  the  2nd  and  4th  decades  of  life.
