Myxoid Cyst – Description and Treatment

Myxoid Cyst
A mucous or

myxoid cyst

is a small, soft nodule that occurs near the end of the fingers or toes. The cause of the cyst is unknown but it is found to appear at the site of an old injury, minor trauma and at the sites of friction. This article gives information on myxoid cysts and their treatment.

Description of Myxoid Cysts:

Myxoid cyst has a smooth shiny surface, appears soft rubbery and is generally skin coloured. It is generally seen at the end of the fingers of hand or toes. These cysts are solitary, dome shaped, round to oval at base, usually ¼ to ¾ inches in diameter. When they burst, they ooze out jelly-like thick liquid, sometimes red due to tinge of blood. Larger the cyst, the more painful it is.

Myxoid cysts are more common in women than in men, the ratio being 2-2.5:1. This cysts are seen more commonly in elderly people, usually from fifth to seventh decades.

Treatment of Myxoid Cysts:

Benign and small myxoid cysts need not be treated as sometimes they disappear by themselves. Some of the treatment options of myxoid cysts include:

  • Sterile squeezing of the contents of the cysts by a needle under the supervision of the specialist.
  • Steroid injections or cortisone injections.
  • Frozen with liquid nitrogen or cryotherapy.
  • Sclerosant injections.
  • Surgical removal of the cysts.

Whatever may be the treatment option, the cysts have high rate of recurrence.

Mostly, these types of cysts are asymptomatic and benign and pain can be only due to impingement of cysts on the adjacent nerves. The larger the cyst, greater is the pain associated with it. Surgery of large cysts can affect the nearest digit and nail deformities can occur as post-surgical complication of the cyst.

Various Therapies Required for Treating Myoxid Cyst:

Although the condition of Myoxid cyst is cured automatically but there is a therapy called Cryotherapy which is very useful in treating the condition. This therapy is discussed below in detail:

Cryotherapy Treatment:

The process of Cryotherapy involves freezing up of the skin, using various methods like carbon dioxide snow, liquid nitrogen and Propane and Dimethyl ether. Liquid nitrogen is most commonly used for treating this condition as it is simple, cheap, safe and more reliable application as compared to others.

  • Liquid Nitrogen Cryotherapy:

    This application requires a cotton-tripped applicator or a cryoprobe along with a cryospray. Now the application of nitrogen is done on the wounded skin and kept for few seconds to enter into it.

  • Carbon dioxide Snow Cryotherapy:

    This treatment requires a tube of icy carbon dioxide flurry which is used for applying it directly to the skin.

  • Propane and Dimethyl Ether Cryotherapy:

    This method requires a foam applicator which is placed on the injured skin. This method takes 20 ““ 50 seconds for treating the wart depending upon its size and location where it is placed.

The above mentioned treatment is carried out by the medical practitioner only after taking a MRI of the wart. Once it is done, doctor will remove all the fluid from the cyst by injecting a syringe inside the cyst and extracting out all the liquid present there.

Only then is the above therapy carried out. Another important point to note here is that the therapy is carried out only when the cyst is not painful.
