Lump In The Hand: Symptoms, Causes and Treatment

Why Do I Have A Lump In The Hand?

About 95% of hand tumors are benign and depending on the type, both treatment and recovery are relatively simple. The most common are ganglion cysts and giant cells of the tendon sheath. Beyond certain annoyances that cause, these malformations do not represent any risk to the health of those who suffer. In this article you will know symptoms, causes and treatments of lump in the hand.


Symptoms associated with lumps in the hand

The symptoms related to the lumps in the hands vary a lot according to several factors such as: the type of tissue, the size and the location. Most of these malformations appear as a visible lump in the hand or wrist. They can form gradually over time or appear suddenly above or below the surface of the skin. Some may be soft, others firm and may or may not move when touched.



Many tumors are painless and are not diagnosed until they interfere with the normal functioning of the hand or increase in size. Tumors that grow near a nerve or in the bone tend to be extremely painful, so their diagnosis is more necessary. Depending on their location, they can affect joint mobility or alter the aesthetics of the hand.

Common types of tumors in the hand

The most common of all these tumors is the so-called ganglion cyst. These are a gelatinous sac that forms outside of an articular or tendon sheath. It appears very frequently on the wrist, but it can also be found around the joints of the fingers. It is generated when a part of the joint capsule becomes inflamed and filled with fluid intended for the lubrication of the joint or tendon



The second most common tumor is the giant cell tumor of the tendon sheath. Unlike the ganglion cyst, which is filled with fluid, these tumors are solid masses. Their growth is slow and they can appear anywhere there is a tendon cover nearby. They unfold in the soft tissue under the skin. These tumors are not malignant.



There are other types of tumors that are less common, among which are:

  • Lipomas (fatty tumors)
  • Neuromas (tumors in the nerves)
  • Glomus tumors (vascular tumor)
  • Fibroids


Why do I have a lump in the hand?

The hand is composed of many different types of tissue (bone, skin, fat, tendons, blood vessels, ligaments, etc.), so it is possible to find many different types of lumps. The causes of its appearance are imprecise but, apparently, the traumatisms play an important role in the development of some.



On the other hand, repetitive movements often produce small lesions that can become inflamed and lead to abnormal cell growth. Also, occasionally, skin cells can be trapped in the tissues, which causes an encapsulation of the same, as a protective response of the body. On the other hand, it is possible, if you suffer from arthritis, that the so-called bone spurs appear, which can be hard and painful.



Another cause that can produce these malformations are foreign bodies, like a splinter, which can generate reactions that form lumps in the hand.



Its location in the hand also depends on the type of tumor. Ganglion cysts are usually located in the joints of the hand and wrist. Those of giant cells of the tendon sheath appear as a solid lump on the palmar surface of the finger and can hinder the complete flexion of the affected finger.



Lump in the hand: Treatment

Most tumors of the hand require surgical intervention to eliminate them completely and avoid recurrence. Normally, these interventions are ambulatory and the return of the patient to their home is estimated on the same day. The extracted tissue is analyzed, because it is the only way to know if it is benign or not. This would be the case in which additional therapy would be required after this intervention, apart from of course therapy to fully recover the functionality of the hand.



95% of these tumors are not malignant. The possibility of cancer is rare, but it can occur. This is why all abnormal growths should be examined by a doctor.
