A ganglion cyst is a swelling that often appears on or around joints and tendons in the hand (or sometime feet). The size of the cyst can vary over time, often becoming more inflamed if irritated. It is most frequently located arond the wrist and on the fingers.

The exact cause of the formation of ganglion cysts is still unknown. They occur more often in elderly people and in females.

They are not generally considered harmful although can cause discomfort and/or limit movement. Frequently, the cysts will disappear over time, so in cases of small cysts that don't cause symptoms, no therapy is necessary. If a ganglion cyst is symptomatic, it can be managed by aspiration or surgery. Aspiration of the cyst is simpler method, but cysts will develop again in about 50% cases. Recurrence rate after surgery is only 5-10%, the procedure is simple and usually there are no complications.
