Ganglion cyst
From Free net encyclopedia
Image:Ganglion-cyst.jpg 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 around the wrist and on the fingers. Image:Ganglion cyst01.png
The exact cause of the formation of ganglion cysts is still unknown. They occur more often in the 20 - 40 age group and in females.
They are not generally considered harmful, although they can cause discomfort and/or limit movement. Frequently, the cysts will disappear over time, so in cases of small cysts that do not cause other symptoms, no therapy is necessary. If a ganglion cyst is symptomatic, it can be managed by aspiration or surgery. Aspiration of the cyst is the simpler method, but cysts will develop again in about 50% of cases. Recurrence rate after surgery is only 5-10%, the procedure is simple, and usually there are no complications.
