Quick answer: Plantar fibromatosis (Ledderhose disease) is a benign thickening of the plantar fascia that forms one or more firm nodules in the arch. It is not cancer and is not the same as plantar fasciitis. Most cases are managed conservatively with arch padding, orthotics, and stretching; steroid injections, verapamil gel, or surgery are reserved for nodules that are painful, enlarging, or limiting walking.

Plantar fibromatosis — known in medical literature as Ledderhose disease — is one of the fibromatoses, a family of benign tumors of fibroblastic origin that also includes Dupuytren’s contracture (palm), Peyronie’s disease (penis), and knuckle pads. Like its cousins, Ledderhose disease involves abnormal proliferation of fibroblasts and collagen within the fascial sheath, leading to nodule formation. The term “plantar fibroma” typically refers to a single isolated nodule; plantar fibromatosis implies multiple nodules or a more aggressive diffuse process. Understanding the distinction matters because treatment approaches and prognosis differ significantly.

What Causes Plantar Fibromatosis

The exact cause is not fully understood, but several factors are consistently associated. There is a clear hereditary component — patients with Ledderhose disease have a significantly higher rate of Dupuytren’s contracture in family members. Trauma to the plantar fascia (repetitive microtrauma or acute injury) appears to trigger the fibroblastic response in genetically predisposed individuals. Associated conditions include: diabetes mellitus, epilepsy treated with phenytoin, chronic alcohol use, and thyroid disorders. Men are affected 2-3 times more frequently than women, and the condition is rare under age 30.

Symptoms

• Firm, palpable nodule(s) along the plantar fascia — usually mid-arch, in the central band of the fascia
• Initially non-tender — early nodules are often discovered incidentally; pain develops as they enlarge or are compressed by footwear
• Pain with barefoot walking or tight shoes — as nodules grow, direct ground pressure becomes painful
• Toe contracture (advanced) — large nodules can tether the plantar fascia, causing the toes to curl downward (rare but reported, especially with multiple large nodules)
• Bilateral involvement — present in 25% of cases at some point in the disease course

Diagnosis

Diagnosis is primarily clinical — a firm, non-mobile nodule adherent to the plantar fascia is pathognomonic. The nodule does not transilluminate (distinguishing it from a ganglion cyst) and is not pulsatile (distinguishing it from a vascular lesion). MRI is the definitive imaging study: plantar fibromatosis appears as a low-signal lesion in both T1 and T2 sequences (reflecting collagenous tissue), typically fusiform, embedded within the plantar fascia. MRI is essential before surgery to define the extent of the lesion and plan the approach. Biopsy is rarely needed — MRI features are highly specific.

Key differentials: plantar wart (superficial, on the skin surface, disrupts dermal ridges, painful with lateral compression), giant cell tumor of tendon sheath (less adherent, more mobile), fibrosarcoma (rare, aggressive, distinguished by MRI signal characteristics and biopsy).

Treatment

Orthotic Offloading

For asymptomatic or mildly symptomatic nodules, custom orthotics with a cutout (donut pad) beneath the nodule redistribute plantar pressure away from the lesion. This does not treat the fibromatosis itself but makes most patients comfortable enough to avoid more invasive treatment. A soft total-contact orthotic with arch support is the foundation of conservative management.

Corticosteroid Injection

Ultrasound-guided corticosteroid injection directly into the nodule can reduce size and tenderness in early, isolated lesions. Response rates vary — approximately 50-60% of patients report improvement, but the effect is often temporary. Injections are not effective for large or longstanding nodules with mature collagen.

Collagenase Clostridium Histolyticum (CCH) Injection

Collagenase injections (Xiaflex — FDA-approved for Dupuytren’s contracture) have been used off-label for Ledderhose disease with promising results in emerging case series. The enzyme dissolves the collagen cords within the nodule, reducing its size. Early evidence suggests efficacy comparable to surgical excision with lower recurrence rates. We offer this at our clinic as a non-surgical option for patients with symptomatic isolated nodules.

Radiation Therapy

Low-dose radiotherapy (total 30 Gy in 10 fractions) is the most effective non-surgical treatment for preventing progression of plantar fibromatosis, particularly in early-stage disease. It does not eliminate existing nodules but stabilizes the disease in 80%+ of patients. Used primarily at specialty centers when disease is progressing despite conservative measures. Referral to radiation oncology is appropriate for rapidly enlarging nodules or bilateral disease.

Surgical Excision

Surgical resection is reserved for painful, functionally limiting nodules that have failed all conservative measures. The critical surgical principle: wide excision of the entire involved plantar fascia segment, not simple enucleation of individual nodules. Simple shelling-out of nodules while leaving surrounding fascia has a recurrence rate exceeding 50% within 2 years. Wide fasciectomy has lower recurrence but carries risk of plantar nerve injury, wound healing complications, and secondary flat foot from fascia removal. Recovery: 4-6 weeks non-weight-bearing, return to full activity at 3-4 months.

Not ideal for: Plantar fibromatosis requiring a custom donut-pad orthotic for pressure offloading beneath the nodule — see us for proper custom casting. PowerStep Pinnacle provides good arch support as a foundation.

Not ideal for: Open wounds. Doctor Hoy’s provides topical comfort for surrounding plantar fascia soreness.

Frequently Asked Questions

Is plantar fibromatosis the same as Ledderhose disease

Yes — they refer to the same condition. Ledderhose disease is the eponym (named after Georg Ledderhose who described it in 1894); plantar fibromatosis is the descriptive pathological term. Both describe the same fibroblastic proliferation within the plantar fascia causing nodule formation.

Is plantar fibromatosis cancer

No — plantar fibromatosis is benign. It does not metastasize. However, it is locally aggressive and has a significant recurrence rate after surgery, which classifies it as a “locally aggressive benign tumor.” The rare exception is fibrosarcoma, which can arise within a pre-existing fibromatosis lesion, but this is extremely uncommon and distinguished by MRI characteristics and biopsy.

Will plantar fibromatosis go away on its own

Spontaneous regression is very rare — plantar fibromatosis is typically a slowly progressive condition. Some patients stabilize for years without growth; others progress steadily. Radiation therapy is the most effective way to halt progression. Observation with orthotic management is appropriate for small, non-painful nodules that are stable on serial examination.

The Bottom Line

Plantar fibromatosis is manageable — most patients with small, stable nodules do well with custom orthotics and monitoring. The decisions get harder when the disease progresses: injection, collagenase, radiation, or surgery each have their place depending on nodule size, symptom severity, and rate of growth. The most important thing is accurate diagnosis (MRI confirms it) and a treatment plan that matches the stage of disease.
