Plantar Fibroma: Lump in Your Arch

Your foot is a unique and important structure that supports your entire body weight and helps you balance. The plantar fascia, a long fibrous tissue that runs along your arch, plays a major role in shock absorption as you walk, jump, or engage in other physical activities. When a benign mass forms on the plantar fascia, it is called a plantar fibroma.

What are the symptoms?

Plantar fibromas often feel like firm lumps in the arch of your foot, are usually half an inch in size but may grow over time and may develop additional fibromas. Although usually painless, larger fibromas may cause pain and discomfort from pressure.


A foot care specialist can diagnose a plantar fibroma through examination, biopsies, and imaging such as MRIs and X-rays.

How is it treated?

Conservative measures are usually sufficient to manage plantar fibromas, unless they cause discomfort or pain from excessive growth, in which case surgical methods may be recommended.

  • Nonsurgical: Custom orthotics to reduce pressure on the fibroma, physical therapy, and medications
  • Surgical: Since fibromas typically recur and removing the fibroma surgically may flatten the arch, surgery is commonly viewed as a last resort for treatment.
