Ganglion cysts of the hand and wrist occur most frequently during the second through fourth decade and women are more frequently affected than men. Ganglion cysts may arise in any location in the hand and wrist but are usually adjacent to joins or tendons and sometimes bones. Patients often present with a history of an asymptomatic mass and many patients seek the advice of a physician because of the cosmetic appearance of the cyst. Observation is acceptable in most instances. Indication for operative treatment includes pain, interference with activity, nerve compression and ulceration of the mucous cysts.
