Cysts near fingernails are called digital myxoid cysts, or digital mucous cysts. They are small, harmless, noncancerous bumps that occur on fingers or toes near a nail bed. The exact cause of myxoid cysts is not known, but they are often associated with osteoarthritis and occur when the connective tissue in the affected digit is weakened. They are usually painless and do not require treatment, but they can be surgically removed if they are bothersome or painful.

Myxoid cysts are noncancerous, fluid-filled lumps that can develop near finger joints and nails
Myxoid cysts are small, noncancerous, fluid-filled lumps that can develop near finger joints and nails. They are also referred to as digital mucous cysts or digital ganglion cysts. These cysts are usually found near the nail on the finger or toe and are often connected to the lining of a nearby joint. They are most common near the nail on the index, middle or ring finger of the dominant hand. In some cases, multiple cysts may appear on the same finger, and they may also appear on several fingers.
Myxoid cysts have a smooth, shiny surface and are usually skin-coloured and almost translucent, with light shining through. They range in size from 5mm to 1cm across, which is about the size of a pencil eraser. The round or oval bumps may be firm or filled with a jelly-like, sticky, thick fluid called synovial fluid. This fluid surrounds joints and tendons, protecting them from damage during movement. Sometimes, this fluid leaks out and may be clear, yellowish or pinkish.
Myxoid cysts are usually painless and do not require treatment. They are not contagious and are often symptom-free. However, you may experience arthritis pain and stiffness in the nearby joint. In rare cases, a myxoid cyst may grow under the nail, which can be painful. It can cause a groove to develop in the nail, slight depressions or colour changes, and the nail may split or be lost. If the cyst is painful or unsightly, or if you are unhappy with the way it looks, you may wish to consider treatment options.
The cause of myxoid cysts is not certain, but they are frequently associated with underlying health conditions such as osteoarthritis. They seem to stem from the degeneration of connective tissue when the lining of the finger joint grows excessively. Myxoid cysts may also be caused by trauma to the finger or toe, or in some cases, by repetitive finger motion. They are more common in females than in males and usually affect adults aged 40 and above, although they can occur at any age.

They are often associated with osteoarthritis and can cause nail deformities
Myxoid cysts are small, noncancerous, fluid-filled lumps that often appear near the nail on the finger or toe. They are also referred to as digital mucous cysts or mucous pseudocysts. The exact cause of myxoid cysts is not known, but they are frequently associated with osteoarthritis. Osteoarthritis and other degenerative diseases can cause the lining of the joints to grow excessively, resulting in the formation of a cyst. An X-ray can be used to confirm the presence of osteoarthritis.
Myxoid cysts are usually not painful and do not require treatment. However, they can occasionally cause nail deformities and other issues. In rare cases, a myxoid cyst may grow under the nail, creating a groove or depression in the nail, or even causing the nail to split or be lost entirely. This can be painful, depending on how much the cyst alters the shape of the nail. The cyst may also feel tender if knocked. In some cases, a cyst may reduce joint movement.
If a myxoid cyst is causing pain or affecting your quality of life, it is recommended to consult a doctor to discuss treatment options. Surgical removal is considered the most effective method, with the least likelihood of recurrence. Nonsurgical treatments are also available, but there is limited evidence of their effectiveness. It is important not to attempt to drain or puncture a myxoid cyst at home, as this can lead to infection.
Myxoid cysts are most common in adults aged 40 and older, with a higher prevalence in females compared to males. They tend to occur on the middle or index finger of the dominant hand. While they can appear at any age, myxoid cysts are more likely to develop in middle age or later. Recurrence rates are high, and even when treated, cysts often reappear.

Myxoid cysts are usually painless and harmless, but some may experience arthritis pain and stiffness in the nearby joint
Myxoid cysts are small, noncancerous, fluid-filled lumps that occur on fingers or toes, usually near a nail. They are also known as digital mucous cysts or mucous pseudocysts. These cysts are not contagious and usually do not cause any pain or other symptoms. However, in some cases, they may be a source of discomfort and can affect one's quality of life.
The exact cause of myxoid cysts is not known, but they are often associated with underlying health conditions, most commonly osteoarthritis. Osteoarthritis is a form of degenerative joint disease, and it is characterised by pain, tenderness, and stiffness in the affected joints. Myxoid cysts are frequently linked to osteoarthritis, with an estimated 64-93% of people with osteoarthritis also having myxoid cysts. The cysts form when the connective tissue around the finger or toe joint degenerates, leading to excessive growth of the joint lining. This degeneration can also cause the formation of small bony outgrowths called osteophytes.
While myxoid cysts themselves are usually painless, the presence of osteoarthritis can lead to arthritis pain and stiffness in the nearby joint. This pain and stiffness are due to the underlying joint degeneration and inflammation associated with osteoarthritis. Additionally, myxoid cysts that grow under the nail or involve the root of the nail can be painful and may cause nail deformities. These nail-related cysts are rare but can lead to grooves, depressions, colour changes, or splitting of the nail.
The occurrence of myxoid cysts is more common in females and older individuals, typically those aged 40 and above. They tend to form on the dominant hand, particularly the middle or index finger, and are less commonly found on the toes. Myxoid cysts can vary in size, ranging from 5 millimetres to 1 centimetre across, and they have a smooth, shiny, and translucent appearance.
Although myxoid cysts often do not require treatment, various options are available if they cause pain, affect quality of life, or are undesirable for cosmetic reasons. Surgical removal is the most effective treatment, with a success rate of over 90%. Nonsurgical approaches have also been explored, such as repeated firm compression, topical steroids, and intralesional photodynamic therapy, but with varying levels of effectiveness.

Treatment options include surgical and nonsurgical methods, but most cysts do not require treatment
Myxoid cysts are noncancerous, not contagious, and usually symptom-free. They are often associated with osteoarthritis in fingers or toes. Myxoid cysts usually don’t require treatment. However, if you do seek treatment, there are several options available, both surgical and nonsurgical.
Surgical methods
Surgical removal is the most effective treatment for a myxoid cyst, with a high success rate ranging from 88% to 100%. During surgery, the cyst is cut away and the area is covered with a skin flap that closes as it heals. The size of the flap is determined by the size of the cyst. The joint involved is sometimes scraped and osteophytes (bony outgrowths from the joint cartilage) are removed. Sometimes, the surgeon may inject dye into the joint to find and seal the point of fluid leakage. In some cases, the flap may be stitched, and you may be given a splint to wear after surgery.
Nonsurgical methods
Nonsurgical treatment options include:
- Using liquid nitrogen, or cryotherapy, to freeze and then thaw the cyst, which can reduce its size but does not prevent the fluid from building up again.
- Draining the cyst by making a puncture, which may need to be done several times. This should only be done by a trained physician in a sterile environment to prevent infection or other complications.
- Injecting the cyst with steroids or chemicals to shrink the volume of fluid.
- Applying pressure to the cyst regularly, which may help it disappear.
It is important to note that recurrence rates are high for myxoid cysts, and they tend to recur after treatment. Treatment options often come with side effects such as pain and scarring.

While the exact cause is unknown, they may be linked to the overproduction of mucin in the skin of the finger or toe
Myxoid cysts are small, harmless, noncancerous bumps that occur on the fingers or toes near a nail bed. They are also known as digital mucous cysts or mucous pseudocysts. The exact cause of myxoid cysts is unknown, but they are often associated with osteoarthritis. Myxoid cysts are usually not painful, but they can be tender if they put pressure on other structures, such as nerves.
While the exact cause of myxoid cysts is unknown, researchers have found that they may be linked to the overproduction of mucin in the skin of the finger or toe. This condition is called focal mucinosis, which is characterised by abnormal deposits of mucins (also known as mucopolysaccharides) in the skin. This type of cyst is different from the type associated with osteoarthritis, which is caused by the overgrowth of the lining of the finger joint.
Focal mucinosis occurs when there is an abnormal buildup of mucins in the skin under the finger or toe. This can result in the formation of a small, shiny lump or growth near the nail. This type of myxoid cyst is also known as a digital pseudocyst because it does not have a capsule surrounding it, unlike true cysts. The pseudocyst is semi-translucent, with a smooth, shiny surface, and it often causes a groove to form in the nail.
The overproduction of mucin in the skin can be due to various factors, such as genetic predisposition, environmental triggers, or a combination of both. In some cases, focal mucinosis may be related to other underlying health conditions. However, more research is needed to fully understand the causes of this condition.
It is important to note that while myxoid cysts are usually harmless, they can sometimes cause discomfort or affect a person's quality of life. If you have a myxoid cyst that is painful, inflamed, or impacting your daily activities, it is recommended to consult a healthcare professional for advice and potential treatment options.
