What You'll Learn
Myxoid cysts are small, noncancerous bumps
Myxoid cysts, also known as digital mucous cysts, are small, noncancerous bumps that appear near the joints of fingers or toes, often close to the nail bed. They are usually harmless and painless, and may disappear without treatment. However, they can be a source of discomfort or pain in some cases, particularly when they are associated with underlying health conditions such as osteoarthritis.
Myxoid cysts are characterised by their small size, typically ranging from 5 millimetres to 1 centimetre in diameter. They are often described as shiny, smooth bumps with a translucent appearance, as light can shine through the skin-coloured surface. These cysts develop under the skin and are attached to the joint by a stalk. They may be firm or filled with a sticky, jelly-like fluid called synovial fluid, which surrounds and protects joints and tendons during movement.
While myxoid cysts usually do not require medical intervention, they can occasionally cause issues. In rare cases, they may grow under the nail, leading to nail deformities such as grooves, depressions, or splitting. This type of cyst can be painful and may require treatment. Additionally, myxoid cysts can put pressure on other structures, such as nerves, resulting in tenderness.
The exact cause of myxoid cysts is not always clear, but they are often associated with underlying health conditions. One of the most common associations is osteoarthritis, where the lining of the finger joint grows excessively. Myxoid cysts may also be linked to focal mucinosis, which occurs when abnormal deposits of mucins (a component of mucus) build up under the skin of the finger or toe. This type of cyst is not associated with joint degeneration.
Although myxoid cysts frequently disappear on their own, various treatment options are available if they persist or cause discomfort. Surgical removal is one effective method, and a doctor can advise on the most appropriate procedure. In some cases, repeatedly pressing firmly on the cyst may help it disappear, although there is a chance of recurrence. It is important to consult a healthcare provider for a proper diagnosis and to discuss suitable treatment options.

They are associated with osteoarthritis
A bump on the finger near the nail matrix could be a myxoid cyst, also known as a digital mucous cyst. These are small, noncancerous bumps that are usually associated with osteoarthritis. Myxoid cysts are most common near the nail on the index, middle, or ring finger of the dominant hand and are typically skin-colored, shiny, and almost translucent. They are usually painless and may go away on their own, but they can cause arthritis pain and stiffness in the nearby joint.
Another possibility is Heberden's nodes, which are small, pea-sized, bony growths that appear on the joint closest to the tip of the finger in people with osteoarthritis. They can cause pain, stiffness, and limited motion in the fingers, making daily tasks difficult. Along with Bouchard's nodes, which appear at the middle joint of the finger, Heberden's nodes are a sign of advanced osteoarthritis of the hands.
Osteoarthritis is a degenerative joint disease that causes the breakdown of cartilage and inflammation over time. It typically affects older adults, with about half of women and one in four men developing osteoarthritis of the hands by the age of 85. The condition can lead to bone spurs or joint cysts, as well as stiffness and pain in the joints due to the rough bone rubbing together without the smooth cartilage.

They are usually painless and may disappear without treatment
A bump on the finger near the nail matrix could be a myxoid cyst, also known as a digital mucous cyst. These cysts are small, noncancerous bumps that are usually associated with osteoarthritis. They are most often found near a joint at the end of your finger, typically near the nail on the index, middle, or ring finger of your dominant hand. Myxoid cysts have a smooth, shiny surface and are usually skin-colored, with a translucent appearance. They are typically round or oval and may be firm or filled with a sticky, jelly-like fluid.
Myxoid cysts usually don't require treatment as they are typically painless and may disappear without intervention. However, if the cyst bothers you, causes pain, or shows signs of infection, it is advisable to consult a healthcare provider. Treatment options include surgical and nonsurgical methods, but these may come with side effects such as scarring and pain, and the cysts tend to recur even after treatment.
The presence of a myxoid cyst may indicate underlying health conditions, particularly osteoarthritis. This condition causes the excessive growth of the lining of the joints, and the cyst appears similar to a ganglion cyst, with a stalk that connects to the joint. Another possible cause is focal mucinosis, which occurs when abnormal deposits of mucins build up under the skin of your finger or toe.
While myxoid cysts themselves typically don't require immediate treatment, it is important to address any underlying health conditions that may be associated with their formation. Consulting a healthcare professional can help identify the specific cause and determine if any further evaluation or management is necessary.
If you are concerned about the appearance of a bump near your nail matrix, it is always advisable to seek the opinion of a medical professional. They can examine the bump, consider your individual circumstances, and provide guidance tailored to your specific situation.

They are typically painless and may disappear on their own. However, if the cyst bothers you, causes pain, or appears infected, you should consider seeking medical treatment.
While myxoid cysts usually don't require treatment, surgical removal is an option if you choose to pursue treatment. Surgical removal is the most effective method to address the cyst. However, it's important to be aware of potential side effects, such as pain and scarring. Myxoid cysts also tend to recur after treatment.
The surgical procedure involves the excision of the cyst, which is performed by a healthcare professional. The specific technique and approach may vary depending on the location and characteristics of the cyst. It is important to discuss the procedure with your healthcare provider to understand the potential risks and benefits.
Before deciding on surgical removal, it is essential to consult a healthcare provider to explore both surgical and nonsurgical treatment options. They will be able to advise you on the most suitable treatment plan based on your individual case. During the consultation, they will examine the cyst, ask questions about it, and provide personalized recommendations.
While surgical removal is an effective option for addressing a myxoid cyst, it is important to carefully consider the potential for scarring and other side effects. Exploring both surgical and nonsurgical options with a healthcare provider will help you make an informed decision about the best course of treatment for your specific situation.

They are most common near the nail on the index, middle, or ring finger
Myxoid cysts, also known as digital mucous cysts, are small, noncancerous bumps that are usually associated with osteoarthritis. They are typically found near the nail on the index, middle, or ring finger of the dominant hand. These cysts develop under the skin and attach to the joint by a stalk, with a smooth, shiny, and almost translucent surface. They are usually skin-coloured and can be firm or filled with a sticky, jelly-like fluid. Myxoid cysts are typically painless and may disappear without any treatment. However, in some cases, they can cause arthritis pain and stiffness in the nearby joint.
The occurrence of myxoid cysts is mostly associated with the dominant hand, making them more common on the index, middle, or ring finger. They are usually found near a joint at the end of the finger, often near the nail. While they typically develop under the skin, attaching to the joint, they can, in rare cases, grow under the nail or involve the root of the nail. This can lead to pain and the formation of a groove down the length of the nail.
The size of these cysts can vary from 5 millimetres to 1 centimetre in diameter, resembling the size of a pencil eraser. Although they are usually painless, you should consult a healthcare provider if they become bothersome, painful, or show signs of infection. Treatment options are available, including surgical and nonsurgical methods. However, it is important to note that these treatments may have side effects such as scarring and pain, and myxoid cysts tend to recur even after treatment.
The exact cause of myxoid cysts remains unknown, but they appear to form when connective tissue weakens and degenerates. There are two variations of myxoid cysts: osteoarthritis, where the lining of the joints grows excessively; and focal mucinosis, where abnormal deposits of mucins build up under the skin or toe. A healthcare provider can diagnose a myxoid cyst through a physical examination, observing and feeling the cyst, and asking relevant questions about it.
