Ledderhose disease, also known as plantar fibromatosis, is a rare, non-cancerous condition that affects the connective tissue in the sole of the foot. It is characterized by the growth of firm nodules in the plantar fascia, the band of tissue that stretches from the heel to the toes. These nodules can cause discomfort, pain, and difficulty walking, which significantly impacts daily life. While benign, the condition often progresses slowly, surprising individuals when symptoms eventually become noticeable. This article explores what Ledderhose disease is, what causes it, how it develops, and the available options for diagnosis, treatment, and long-term management.

Ledderhose disease is a benign fibroproliferative disorder of the plantar fascia. The plantar fascia is a tough, fibrous band of tissue that supports the arch of the foot. In Ledderhose disease, fibrous nodules form within this structure, usually along the medial (inner) side of the arch. These nodules are typically firm and rubbery and can vary in size. The condition is named after Dr. Georg Ledderhose, who described it in the late 19th century. Importantly, Ledderhose disease shares similarities with Dupuytren’s contracture, which affects the hand, and Peyronie’s disease, which affects the penis. These related conditions suggest a common underlying mechanism involving abnormal fibroblast activity and collagen production.

The exact cause of Ledderhose disease remains uncertain, but researchers believe that a combination of genetic, mechanical, medical, and lifestyle factors plays a role. While anyone can develop the condition, certain risk factors are more strongly associated with its development.

• Genetics: Family history of Ledderhose disease, Dupuytren’s contracture, or Peyronie’s disease increases the likelihood of developing plantar fibromatosis. Genetic alterations that affect collagen metabolism or fibroblast function may predispose individuals to the condition.
• Repetitive trauma: Continuous stress or micro-injury to the foot, such as from running, jumping, or standing for long periods, may encourage the formation of nodules.
• Medical conditions: Diabetes, thyroid disease, liver disease, epilepsy, and alcohol use disorder are commonly linked to higher risk.
• Medications: Some anticonvulsants, particularly phenytoin, have been associated with fibromatosis.
• Age and gender: The condition occurs more often in middle-aged and older adults and is more common in men.
• Smoking: Tobacco use may impair tissue healing and collagen metabolism, encouraging fibrotic changes.

Ledderhose disease develops due to an abnormal proliferation of fibroblasts, which are cells that produce collagen and other structural proteins. In this condition, fibroblasts become overactive, leading to the formation of dense fibrous nodules in the plantar fascia. Over time, these nodules may enlarge, harden, and disrupt normal foot mechanics. The disease progresses slowly, and in many cases, the nodules remain painless for years before causing symptoms. Unlike cancerous growths, Ledderhose nodules do not spread to other parts of the body, but they can recur after treatment and sometimes become resistant to conservative therapies.

Ledderhose disease is rare compared to related conditions like Dupuytren’s contracture. It most commonly appears in men over the age of 40, with a male-to-female ratio of at least 2:1. The condition may affect one or both feet, although bilateral involvement is common in more advanced cases. Geographic variation exists, with higher prevalence in populations of Northern European descent. While exact incidence rates are not well established, the condition is considered underdiagnosed, particularly in its early stages, when nodules are small and painless.

The symptoms of Ledderhose disease vary widely depending on the size, number, and location of the nodules. For many people, the condition is painless in its early stages, but as the nodules enlarge, discomfort and functional limitations may arise.

• Firm nodules in the arch of the foot that feel rubbery and non-movable
• Pain or discomfort when walking, running, or standing for long periods
• Swelling or tenderness around the nodules
• A sensation of something pressing against the sole inside shoes
• Difficulty walking or altered gait due to disrupted foot mechanics
• Rare skin changes such as puckering or dimpling above the nodules
• Involvement of both feet in more advanced disease

Diagnosis usually begins with a physical exam, during which the healthcare provider palpates the underside of the foot to identify nodules. Imaging may be used to confirm the diagnosis or to rule out other conditions.

• Physical exam: Clinical evaluation involves checking the size, number, and consistency of nodules, as well as assessing tenderness and skin mobility.
• Ultrasound: This non-invasive test helps visualize soft tissue structures, confirm the presence of nodules, and differentiate them from cysts or lipomas.
• MRI: Magnetic resonance imaging is useful in complex or severe cases, especially for pre-surgical planning.
• Biopsy: Rarely performed, biopsy may be used when there is concern about malignant growths, though cancer is extremely rare in this condition.

Differential diagnosis for Ledderhose disease

Because other conditions can present with lumps or pain in the sole of the foot, healthcare providers must distinguish Ledderhose disease from other disorders. Conditions that may be considered include:

• Plantar fasciitis
• Plantar fibroma (solitary nodule)
• Ganglion cyst
• Lipoma
• Sarcoma (extremely rare)

There is no cure for Ledderhose disease, but treatment aims to reduce symptoms, slow progression, and improve mobility. Management strategies range from conservative care to surgery, depending on disease severity.

Conservative treatment

Conservative management is often recommended as the first approach, especially for smaller or less symptomatic nodules.

• Footwear modifications: Soft cushioned shoes or custom orthotics reduce pressure on nodules. Avoiding barefoot walking may help.
• Physical therapy: Stretching, massage, and therapeutic ultrasound can ease discomfort and improve flexibility.
• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) or topical gels reduce pain and inflammation.
• Corticosteroid injections: Injections into nodules may provide temporary pain relief but carry risks with repeated use.
• Radiation therapy: Low-dose radiation may help shrink nodules in early-stage disease.
• Collagenase injections: Still experimental, these aim to break down fibrous tissue, as used in Dupuytren’s treatment.

Surgical treatment

Surgery is considered when conservative methods fail or when nodules are large, painful, or rapidly growing.

• Fasciectomy: A partial fasciectomy removes nodules and part of the affected fascia, while complete fasciectomy is rarely performed.
• Risks: Recurrence is common, with up to 60% of patients experiencing regrowth. Scar tissue, wound complications, and long recovery times are also concerns.
• Rehabilitation: Postoperative care includes immobilization, gradual weight-bearing, and physical therapy.

Alternative and experimental therapies

• Shockwave therapy: Sound waves may stimulate tissue healing and reduce pain.
• Cryotherapy: Freezing nodules with liquid nitrogen is being studied but is not yet widely available.
• Orthotic devices: Insoles or custom orthotics relieve pressure and redistribute weight away from nodules.

While not life-threatening, Ledderhose disease can significantly impair quality of life. Complications may include chronic pain, altered gait leading to secondary joint problems, and recurrence after surgery. In rare cases, severe contractures or deformities may develop if nodules are large or untreated. Emotional distress, frustration, and reduced mobility are also common challenges faced by patients.

The outlook for Ledderhose disease varies widely. For some, nodules remain small and painless for years, requiring little intervention. For others, the condition progresses, causing chronic pain and disability. Even with treatment, recurrence is common, especially after surgery. Nonetheless, with early diagnosis and appropriate care, many individuals manage symptoms effectively and maintain an active lifestyle.

There is no guaranteed way to prevent Ledderhose disease, but certain lifestyle choices may reduce risk or slow progression. Protective footwear, avoidance of repetitive foot trauma, and smoking cessation are important considerations. Managing underlying medical conditions such as diabetes or thyroid disease can also support connective tissue health. People with a family history of fibromatosis should remain vigilant for early signs and seek medical evaluation if nodules appear.

Living with Ledderhose disease requires a combination of medical management and practical self-care. Early recognition and lifestyle adjustments can make a significant difference in long-term outcomes. Supportive footwear, physical therapy, and conservative treatments often allow individuals to maintain mobility. Emotional support and patient education are also essential, as the condition can cause frustration when symptoms recur or interfere with daily life. Many patients benefit from joining support groups or engaging with healthcare teams who specialize in connective tissue disorders.

Ledderhose disease is a rare, benign condition that affects the plantar fascia, leading to fibrous nodules in the sole of the foot. Although not cancerous, the disease can cause significant discomfort, pain, and mobility issues. Its development is linked to multiple risk factors, including genetics, repetitive trauma, and underlying health conditions. While no cure exists, treatments ranging from conservative measures to surgery can improve symptoms and quality of life. Early recognition, tailored treatment, and ongoing care are key to managing the condition. With the right approach, most individuals can continue leading active and fulfilling lives.
