Quick answer: A plantar fibroma is a benign, firm nodule in the plantar fascia on the bottom of the foot, usually in the arch area. Most plantar fibromas are painless or mildly painful and don’t require treatment. Painful fibromas can be managed with orthotics and cortisone injections. Surgical excision is effective for refractory cases but carries a high recurrence rate.
The most important clinical decision with Plantar Fibroma isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.

Finding a firm lump in the arch of your foot can be alarming — but most of the time, it’s a plantar fibroma, a completely benign growth. It’s not a tumor in any dangerous sense. In our clinic, we’ve seen plantar fibromas sitting stable for years without causing any significant problem. The important questions are: is it growing, is it painful, and is it changing how you walk?

What Is a Plantar Fibroma?
A plantar fibroma is a benign fibromatous nodule that develops within the plantar fascia — the thick band of tissue along the bottom of the foot. It is a form of plantar fibromatosis (also called Ledderhose disease), a condition where fibrous tissue in the plantar fascia proliferates to form one or more firm nodules. These nodules are typically located in the medial (inner) or central band of the plantar fascia, usually in the arch region between the heel and ball of the foot.
Plantar fibromas are distinct from plantar warts (which are viral, on the skin surface) and from plantar fasciitis (which involves inflammation of the fascia without a mass). They are benign — they do not metastasize — but they can grow and multiply over time.
Key takeaway: A new lump in the arch of the foot should be professionally evaluated — most are plantar fibromas, but imaging confirms the diagnosis and rules out rare soft tissue tumors.
Symptoms of Plantar Fibroma
Many plantar fibromas are discovered incidentally — the patient feels a lump while rubbing their foot and it isn’t causing pain. When symptoms do occur: a firm, slow-growing nodule palpable in the arch of the foot (typically 0.5–3 cm), pressure-related pain when walking barefoot or in thin-soled shoes, discomfort with prolonged standing, and in larger or multiple fibromas, arch pain that impacts walking mechanics. Fibromas typically do not cause radiating pain, numbness, or tingling (which would suggest nerve involvement).
What Causes Plantar Fibromas?
The exact cause is not fully understood, but associated factors include: genetic predisposition (Ledderhose disease runs in families and is associated with Dupuytren’s contracture of the hand and Peyronie’s disease), repetitive microtrauma to the plantar fascia, chronic use of certain medications (beta-blockers, anti-epileptics, high-dose vitamin C), alcohol use, and liver disease. The condition is more common in men and in middle-aged adults.
Key takeaway: Plantar fibromatosis is associated with Dupuytren’s contracture of the hands — if you have nodules in your palms, your plantar arch lumps are almost certainly fibromas.
Plantar Fibroma Treatment Options
No treatment is required for asymptomatic fibromas. For painful or growing lesions:
- Custom orthotics with fibroma accommodation — a cutout in the arch relieves direct pressure on the nodule; very effective for mild-to-moderate symptoms
- Arch-supporting insoles — soft arch support shifts load away from the fibroma
- Corticosteroid injection — can temporarily reduce fibroma size and soften the tissue, providing months of relief; not a permanent cure
- Verapamil gel — topical calcium channel blocker; reduces fibromatosis proliferation in some cases; applied daily for months
- Collagenase injection — enzymatic dissolution of fibrous tissue; emerging treatment with promising early results
- Radiation therapy — used in Europe for extensive plantar fibromatosis; data suggest it can halt growth and reduce symptoms without surgery
- Surgical excision — removes the fibroma and a margin of surrounding fascia; high recurrence rate (20–50%) and risk of plantar fasciitis post-operatively; reserved for refractory, severely symptomatic cases
The most common mistake we see is patients requesting immediate surgical removal of a recently discovered, small, asymptomatic fibroma. Given the high recurrence rate and surgical risk, watchful waiting with orthotics is the appropriate first approach.
⚠️ When to see a podiatrist:
- Nodule is growing rapidly (more than 1 cm per month)
- Overlying skin changes — hardening, redness, or tethering
- Multiple nodules spreading toward the toes
- Significant gait alteration due to size or pain
- Any soft tissue mass that feels different from prior evaluation (needs MRI to confirm benign nature)
Frequently Asked Questions
Is a plantar fibroma dangerous? No — plantar fibromas are benign and do not become cancerous. However, any new foot mass should be professionally evaluated to confirm the diagnosis, as rare soft tissue sarcomas can occasionally present similarly.
Will a plantar fibroma go away on its own? Unlike some soft tissue masses, plantar fibromas rarely resolve spontaneously. They tend to remain stable or grow slowly over time. Treatment reduces symptoms but typically doesn’t eliminate the fibroma permanently without surgery.
Can I have a plantar fibroma removed? Yes — surgical excision is performed under local anesthesia in an outpatient setting. However, we counsel all patients that recurrence rates are 20–50%, and some patients develop more extensive fibromatosis after surgery. We exhaust conservative measures first for this reason.
Podiatrist-Recommended Products for Plantar Fibroma
These are the products Dr. Biernacki most commonly recommends to plantar fibroma patients at Balance Foot & Ankle. They address the two biggest concerns: offloading pressure from the nodule and reducing discomfort during recovery.
Metatarsal Pad / Arch Offloading Insole
A metatarsal or arch-relief pad placed just behind the fibroma redistributes pressure away from the nodule with every step. This is often the single most effective conservative measure — far cheaper than cortisone. Look for a 3/16” felt or foam pad that can be trimmed to fit directly into your existing shoe. Dr. Biernacki recommends placing it so the raised portion sits proximal (behind) the fibroma, not on top of it.
HOKA Bondi 8 — Rocker Sole, Maximum Cushion
The HOKA Bondi 8 is the shoe Dr. Biernacki recommends most often for plantar fibroma patients who want to stay active. The thick, maximally-cushioned midsole and built-in rocker geometry reduce peak pressure under the arch by rolling the foot forward rather than compressing through it. Wide toe box available. Available in wide widths. Pairs perfectly with the metatarsal pad above.
Topricin Foot Pain Relief Cream
Topricin Foot Therapy Cream is a homeopathic topical that many fibroma patients find helpful for managing the associated arch soreness. Unlike cortisone, it can be used daily without tissue-thinning concerns. Apply to the arch and surrounding tissue twice daily. It won’t shrink the fibroma itself, but it addresses the inflammatory ache around the nodule that makes walking uncomfortable.
Plantar Fascia Night Splint
Because plantar fibromas grow along the plantar fascia, keeping the fascia gently stretched overnight can reduce morning stiffness and the sharp first-step pain that many fibroma patients experience. A dorsiflexion night splint holds the foot at 90° while you sleep, preventing the fascia from tightening around the nodule. Most patients notice improvement within 2–3 weeks of consistent use.
The Bottom Line
A plantar fibroma is almost always benign, and most respond adequately to pressure offloading with custom orthotics. If you’re concerned about a lump in your foot arch, our team at Balance Foot & Ankle will confirm the diagnosis, characterize the fibroma with imaging if needed, and guide you through the most appropriate management for your specific lesion — without unnecessary surgery.

👟 Conservative plantar fibroma management: PowerStep Pinnacle + Doctor Hoy’s
Plantar fibromas respond poorly to rest alone. The goal is reducing pressure directly on the nodule while maintaining mobility. PowerStep Pinnacle insoles with a custom cutout over the fibroma offload the nodule during weight-bearing — your podiatrist can mark the modification spot. Doctor Hoy’s arnica gel applied around (not on) the nodule may reduce surrounding tissue inflammation.

When a plantar fibroma starts catching on the ground
Small, asymptomatic plantar fibromas can be watched. The decision point is when the nodule starts hurting on standing, catching in shoes, or growing on serial measurement. Conservative care includes orthotic offloading, steroid injection, and verapamil 15 percent gel; intra-lesional therapies and excision are reserved for refractory cases. We can confirm the diagnosis with ultrasound and image-guide any injection in office.

📋 Dr. Tom Biernacki, DPM, FACFAS answers:
Most plantar fibromas do not need surgical removal. These benign, firm nodules in the plantar fascia are best managed conservatively: custom orthotics with accommodation to offload the nodule, corticosteroid injections to reduce size (effective in about 50% of cases), transdermal verapamil gel applied twice daily, and physical therapy stretching to maintain fascia flexibility. Surgery is considered only when the fibroma is rapidly growing, causing unmanageable pain despite 6+ months of conservative care, or significantly limiting walking. Surgical excision is complicated by the fibroma’s involvement with the plantar fascia — the fascia must be partially removed with the nodule, risking post-operative flat foot deformity and a recurrence rate of 30–50%. Many patients manage fibromas conservatively for years without surgery.
