Patients are understandably alarmed when they discover a lump in their foot. At Affiliated Foot & Ankle Care, the good news we can deliver to patients is that this lump is sometimes diagnosed as plantar fibroma, in which case the lump is benign and not a sign of cancer.

Mysterious Fibroma

A fibroma is a fibrous knot or nodule that forms along the plantar fascia—a long band of tissue that runs along the bottom of your foot from heel to toe. Oftentimes a fibroma is not painful and patients may not notice it until they feel it. In other cases, the pressure from shoes or even from standing, if it’s a larger fibroma, can start to cause pain or discomfort. It’s unclear what causes a fibroma, but if you detect a lump in your arch, one of our podiatrists, Dr. Varun Gujral or Dr. Nrupa Shah will examine your foot and manipulate the part of your arch with the lump. An MRI or biopsy may also be ordered to further aid in the diagnosis.

Treatment Options

A plantar fibroma will not go away on its own. The only way to remove it is through surgery. However, surgical removal may result in the flattening of the arch of the foot or in hammertoes developing. Nonsurgical treatments may bring pain relief, however. These include:

  • Physical therapy
  • Steroid injections—these can help shrink the fibroma, which can decrease pain and increase comfort. The size reduction may be temporary, however.
  • Orthotic devices—if the fibroma is stable and not growing, the foot doctor may fit you with an orthotic insert for your shoe that will shift your weight away from the fibroma and thereby give you relief from the pain.

If you have found a lump in the arch of your foot (or anywhere else on your foot for that matter), contact our Edison, Monroe or Monmouth Junction office as soon as possible by calling: 732-662-3050. In nearly all cases, seeking medical care sooner rather than later for foot issues will result in more effective treatment with less chance of chronic pain or long term disability.
