What Is a Plantar Fibroma?
A plantar fibroma is a benign (non-cancerous) nodule that grows within the plantar fascia — the strong band of tissue running along the sole of the foot from the heel to the toes. When multiple nodules develop, or the tissue thickens more extensively, the condition is known as plantar fibromatosis or Ledderhose disease.
The nodules are made of fibrous tissue and usually sit in the arch (the instep), most often in the middle third of the sole. They are firm, fixed to the fascia, and range from a few millimetres to several centimetres. Although benign, they do not usually disappear on their own.
Why it matters: because the nodule sits in the weight-bearing arch, even a small fibroma can become painful when walking, standing or wearing firm shoes. It is closely related to Dupuytren’s disease of the hand.
