A plantar fibroma is a firm lump that appears on the sole of the foot. These nodules are benign but can cause some pain in the arch when you are standing or walking. Plantar fibromas are about an inch in diameter, and sometimes develop into clusters. These growths do not usually go away on their own, and may need to be removed surgically if they inhibit your daily activities. The cause of plantar fibromas is largely unknown, but a number of conditions may be linked to their formation. A family history of plantar fibromas is the most common risk factor. Men are twice as likely to develop plantar fibromas than women. Certain medical conditions, such as diabetes and liver disease, are believed to be associated with fibroma development. Long term alcohol consumption is considered another risk factor. Healing from repetitive stress to the plantar fascia is thought to be a factor. A number of non-surgical as well as surgical treatments are available to remove plantar fibromas. It is suggested you visit a podiatrist for an exam and the treatment options that are best for you.

Plantar Fibroma

A plantar fibroma is a fibrous knot in the arch of the foot. It is embedded in the plantar fascia which is a band of tissue that extends from the heel to the toes along the bottom of the foot. There can be multiple plantar fibromas in the feet at the same time. There are no known causes for this condition. If you have a plantar fibroma, there will be a bump in the arch of your foot that cannot be missed. Any associated pain is most often due to a shoe rubbing against the nodule. Non-surgical options, such as steroid injections, physical therapy, and orthotics should be tried first. Surgery is a last resort and is the only thing that will remove a plantar fibroma entirely. Consult with a podiatrist for a proper diagnosis and to determine the treatment regimen that is right for you.

What Causes a Plantar Fibroma?

While there are no specific causes identified, a plantar fibroma can possibly come from genetic predisposition or the formation of scar tissue that forms from healing the tears in the plantar fascia.

What Are the Symptoms of a Plantar Fibroma?

There will be a noticeable lump in the arch of the foot that may or may not cause pain. If pain is felt, it is typically because a shoe is rubbing up against the lump or when walking or standing barefoot.

Treatment and Prevention

A plantar fibroma will not disappear without treatment, but it can get smaller and be a non-issue. If pain persists, a podiatrist examines the foot and when the arch of the foot is pressed, pain can be felt down to the toes. An MRI or biopsy might be performed to help diagnose or evaluate the plantar fibroma. The following non-surgical options are generally enough to reduce the size and pain of these nodules:

• Steroid injections
• Orthotics
• Physical therapy to help apply anti-inflammatory creams on the bump 

Surgery is considered if the mass increases in size and the patient continues to feel pain after non-surgical methods are tried.
