Epidermal inclusion cyst of the finger, a type of tumor that forms just underneath the skin where there may have been a cut or puncture.
Figure 4. Figure 1 Close. This damage activates the fibroblast cells in the connective tissues to produce hyaluronic acid that accumulates to form the jellylike content of the cyst [1]. Ganglion cysts usually occur in gymnasts and other professionals who are involved in stressful, repetitive movement at the wrist joint. The cysts typically appear as a lump of about 1cm to 3cm in size, and are mostly part of the underlying connective tissue, rather than the skin.
When the cyst is on the palmar volar ganglion side of the hand, the swelling can cause injury to the ulnar nerve, and may also press on the radial artery, thereby resulting ischemia reduced blood flow to the hand. Other explanations for the cause of ganglion cyst suggest that the damage to the joint caused the breakdown of tendon sheath or capsule, thereby forming small cysts that develop into large mass typical of ganglion cysts.
The symptoms of ganglion cysts are typically mild. Symptoms of ganglion cyst are swelling of the hand or wrist, pain in the joint or hand due to swollen tissues impinging on nerves of the wrist, weakness in hand muscles in severe cases , dissatisfaction with cosmetic appearance, and tingling sensation [3][4]. Ganglion cyst is very easy to diagnose.
Doctors or clinicians will perform a physical examination of the affected hand or body part. Ultrasound imaging can be used to provide a better view of the cyst. Ultrasound can be used to determine whether the cyst is fluid filled or if it has become a solid mass.
Ultrasound image of the hand can also distinguish the ganglion cyst from vascular malformation. What are some non-cancerous growths that may crop up from the interior of the wrist or the base of the hand? The most common kind of growth originating in the wrist, and in the hands, is a ganglion cyst. Usually, these cysts are painless and go away on their own. A simple surgery may get rid of the ganglion cyst while also reducing the chances of re-occurence, and there are also a few nonsurgical treatments you can discuss with your physician.
These masses can show up in the hands, as well as the wrists, slowly growing out of the tendon sheath. These bony growths crop up at the base of the back of the hands, at or near the junction with the wrists. Inclusion cysts are caused when a penetrating wound, such as a deep cut, pushes surface cells into the deep layers of the hand or finger.
These cells, considered foreign, are encapsulated by the immune system and gradually expand in size over time. Carpal boss is the overgrowth of bone on the back of the hand similar in appearance to a bone spur.
It is essentially a small area of osteoarthritis occurring at the junction of the long hand bones and small wrist bones. While frequently misdiagnosed as a ganglion cyst, a carpal boss is invariably firmer and fixed in its position. Unlike a cyst, you cannot move it or feel any "give" when you press on it. Enchondroma is a noncancerous tumor that develops when cartilage grows inside a bone. An enchondroma can become a problem if and when the tumor weakens the bone, increasing the risk of a pathologic fracture.
When cancer develops beneath the skin of the hand or wrist, it is most often due to a malignancy that has spread metastasized from a tumor in another part of the body, most often the lungs. The hand and wrist are not common locations for cancers to spread, but it is not impossible.
While cancer seldom originates in the hands or wrists, there are rare cases where tumors have formed in the bone or cartilage of the hand. By contrast, one in five children with cancer will have a sarcoma. They predominantly develop in soft tissue such as fat and muscle , although around 10 percent will occur in the bones of the hands or wrists.
It is not entirely clear what causes sarcoma. Family history and exposure to chemicals or radiation are known to play a part. In most situations, the cause is not clear. These types of cancers are serious problems that often require invasive treatment and prolonged care.
It is important to have this condition fully evaluated when there is a concern for a sarcoma. The vast majority of lumps and bumps on the hand and wrist are small symptoms of a minor condition. That said, there are situations that can be more worrisome. While most often these lumps and bumps can be managed with simple treatments, there are times when they are signs of a more serious problem.
