What Is a Plantar Fibroma?

A plantar fibroma is a ball of fibrous tissue that develops in the arch of the foot. Though plantar fibromas are benign, they can cause a great deal of pain and interfere with walking and standing. Interestingly, these happen in males more often than females and in middle aged versus older people. When several fibromas develop in the feet, it is called plantar fibromatosis. Pain can worsen as fibromas become larger, from wearing shoes that are too tight, from walking barefoot, or from standing too long. These lumps have no known cause, but may be genetic. They are more common in those of Northern European heritage and less common in Asians. Some experts think trauma and repetitive injuries to the feet may be involved in the development of plantar fibromas. Medical conditions, such as liver disease and diabetes, and lifestyle factors, including alcohol abuse, might also contribute to, but not cause, formation of plantar fibromas. Also, certain medications and supplements are associated with this condition. If you think you have a plantar fibroma, it is suggested that you see a podiatrist for a proper diagnosis and treatment.

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.
