Plantar Fibroma

A plantar fibroma is a fibrous knot in the arch of the foot. This nodule is embedded within the plantar fascia, a band of tissue on the bottom of the foot that connects the heel to the toes. A plantar fibroma can develop in one, or both feet, is benign (non-malignant), and usually will not disappear without treatment. The causes of a plantar fibroma have yet to be found.


The characteristic sign of a plantar fibroma is a noticeable lump in the arch of the foot. This bump will feel firm to the touch, and could potentially get bigger as time goes on. Additional fibromas, or alternate diagnoses may develop if preventative or mitigatory action is not taken early.

Pain may or may not be present. Most often, when pain occurs, it is caused by shoes pressing against the mass within the arch. However, it can be painful to walk or stand barefoot, depending on the severity of the fibroma.

Surgical removal of a Plantar fibroma is usually executed by flattening the arch. Due to the high recurrence rate of a plantar fibroma, continued and consistent follow-up care with your foot and ankle surgeon is strongly recommended.
