Is Ledderhoses Disease / Plantar Fibromatosis contagious?

Ledderhose disease, also known as plantar fibromatosis, is a non-malignant, non-contagious condition characterized by the growth of benign nodules in the plantar fascia of the foot. It cannot be spread to others through touch, proximity, or daily interaction, as it is a localized proliferative disorder of the connective tissue rather than an infectious disease.

Is Ledderhose disease contagious in any way?

No, Ledderhose disease is not contagious. There is no infectious agent, such as a bacteria, virus, or fungus, involved in the development of plantar fibromatosis. You cannot "catch" this condition from someone else, nor can you transmit it to family members, partners, or children. Because Ledderhose disease is a result of abnormal collagen production and fibrous tissue growth within your own body, it poses zero risk to those around you, regardless of physical contact or shared living spaces.

What causes Ledderhose disease if it is not an infection?

Ledderhose disease is categorized as a benign proliferative disorder. While the exact underlying cause remains a subject of ongoing medical research, it is generally considered a multifactorial condition influenced by genetic predisposition and cellular changes. The condition involves the over-proliferation of fibroblasts, which are cells responsible for creating connective tissue. This leads to the formation of firm, often painless nodules along the arch of the foot. Unlike infections that trigger an immune response, this condition is a localized thickening of the fascia that does not involve pathogens.

Why is there sometimes confusion regarding the cause?

Patients with Ledderhose disease may occasionally face stigma or confusion from others who mistake the visible nodules for warts, cysts, or infectious skin conditions. Because the nodules appear on the skin's surface, observers unfamiliar with the condition may incorrectly assume they are contagious. However, clinically, these nodules are deep-seated fibrous growths, not surface-level infections. Within the DiseaseMaps community, where 95 people with Ledderhose disease have shared their experiences, members often emphasize that the condition is a systemic or localized tissue response, not a communicable illness.

Are there environmental or genetic triggers?

While Ledderhose disease is not caused by an external germ, certain factors may trigger or exacerbate the growth of nodules in predisposed individuals:

• Genetic factors: A family history of fibromatosis (including Dupuytren’s contracture of the hand) is often noted, suggesting a hereditary link.


• Micro-trauma: Repeated stress or minor injuries to the sole of the foot may stimulate the proliferation of fibrous tissue.


• Alcohol consumption and smoking: Some clinical literature suggests these may be associated with the progression of fibromatosis conditions.


• Diabetes and epilepsy: There is a documented clinical association between Ledderhose disease and certain metabolic or neurological conditions, though the exact biological mechanism remains under investigation.

Next steps

• Consult a podiatrist or orthopedic surgeon to accurately diagnose your symptoms and rule out other foot conditions.


• Educate family and friends by sharing reliable resources to dispel any myths regarding the "contagious" nature of your condition.


• Connect with the 95+ members on DiseaseMaps.org to share experiences and coping strategies for managing plantar fibromatosis in daily life.


• Keep a symptom diary to track if specific activities or footwear impact the size or sensitivity of the nodules.
