Ganglion cyst
Ganglion Cyst
A Ganglion Cyst (pronunciation: GANG-glee-on SIST) is a noncancerous lump, often on the tendons or joints of wrists and hands. They can also appear on the ankles and feet. Ganglion cysts are filled with a jellylike fluid.
Etymology
The term "Ganglion" comes from the Greek word "ganglion," which means "knot" and is used to describe the knot-like mass or lump that forms below the surface of the skin.
Description
Ganglion cysts are common and harmless. They occur in various sizes, and the same person may have more than one. Sometimes these cysts can be painful, especially when they press against a nerve. In many cases, they do not hurt and require no treatment.
Causes
The cause of ganglion cysts is not known, but any joint or tendon sheath can develop a cyst. The cysts are connected to the joint or tendon sheath by a stalk that allows fluid to flow into the cyst.
Symptoms
Symptoms of a ganglion cyst may include:
- A noticeable lump—often this is the only symptom experienced
- Tingling or burning, if the cyst is touching a nerve
- Dull pain or ache, which may indicate the cyst is pressing against a tendon or joint
- Difficulty wearing shoes due to irritation between the lump and the shoe
Treatment
Treatment can often be non-surgical. In many cases, these cysts can simply be observed to make sure that they do not press on nerves. In cases where the cyst is painful, a doctor might choose to aspirate the cyst with a needle. Removing the cyst surgically is generally an outpatient procedure and is performed when the cyst causes symptoms or becomes a cosmetic concern.
