One of the most common diseases of hands is cyst or hygroma. A hygroma is a convex compaction of the skin in the tendon area of hands, wrists, or feet, which size is comparable to the size of a small pea or sometimes to a large nut. Do not confuse this pathology with a cancerous tumor, because the causes of both diseases are entirely different. In the case of hygroma, the provoking factor is the filling of the fibrous membrane with liquid, which causes the appearance of a bump on the surface of the skin.

Symptoms of hygroma

At first, hygroma manifests itself in the form of slight swelling. At this stage, the formation looks like a bruise and may not cause much discomfort. Gradually the swelling increases in size and acquires a rounded shape. When touching, some liquid is felt inside of it. If there is no appropriate treatment, the disease can become chronic; it will not grow or cause any discomfort. But in some time the person who has such a disease may feel severe pain in the area of bump. It is called the period of exacerbation.

Hygroma can appear suddenly and sharply grow to half an inch in diameter in a couple of days or can develop over time. A patient may notice this disease after feeling some pain in the surrounding tissues.

Sometimes hygroma may open with no help from a doctor because of trauma or features of the body. In this case a large and painful wound forms in the area of the hygroma.

What causes hygroma?

The appearance of a cyst on hands sometimes does not have typical causes, but it is very often formed due to bruises, injuries, excessive strain on joints, or because of the monotonous, rhythmic and prolonged movement.

The most common type of cyst is considered to be wrist hygroma. There are many factors that can provoke the appearance of this pathology. However, the main reasons are genetic inheritance, monotonous handwork, old traumas that were not treated well.

Athletes have a high predisposition to such disease, as during training they do exercises that influence their hands a lot and cause high pressure in upper limbs. For example, people who do ping-pong, tennis, golf, or badminton are in danger of getting this disease. Also, the cyst is an industrial disease of many musicians who play the piano, violin, cello, etc. In addition, many typists, seamstresses, embroiderers very often face a similar diagnosis.

Ligament sprains, bruises, falls, dislocation, or fractures can also be the causes of cysts. The pathology has no age limits; therefore, both adults and children can have it.


It is important to visit the doctor when you just noticed any symptoms of hygroma. In this situation, the treatment of it will be less harmful. It can be easily pierced with a syringe that will pump the liquid. But if you visit the doctor when the disease has already developed only surgical intervention can help. After the elimination of the cyst, it is necessary to restrict the movement of the weakened joints to heal injuries. During the treatment, the causes of hygroma have to be recognized because it will help to prevent re-formation of the cyst.

So, if you get hygroma you should not be afraid of it as it has no connection to cancer. The only thing you should do is go to hospital. You will have fewer chances to develop any complications.
