What is the prevalence of Ledderhoses Disease / Plantar Fibromatosis?

TL;DR: Ledderhose disease, or plantar fibromatosis, is a rare condition characterized by the formation of benign nodules on the sole of the foot, with an estimated prevalence that remains poorly defined due to significant underdiagnosis. While exact global population statistics are limited, clinical literature suggests it is most common in middle-aged to older adults and occurs more frequently in males than in females.

What is the estimated prevalence and incidence of Ledderhose disease?

Determining the precise prevalence of Ledderhose disease is challenging because many individuals with mild or asymptomatic cases never seek medical attention. According to data from the NIH Genetic and Rare Diseases Information Center (GARD), Ledderhose disease is classified as a rare disorder. Unlike some conditions with clear registry data, no definitive global incidence rate exists. However, it is clinically recognized that Ledderhose disease is significantly more common than its palmar counterpart, Dupuytren’s contracture, in certain clinical settings, though overall, it is considered an infrequent finding in primary care practice.

Who is most likely to be affected by Ledderhose disease?

The demographic profile of Ledderhose disease shows distinct patterns regarding age and gender. While children can be affected, it is predominantly a condition of adulthood, with the typical age of onset occurring between 40 and 60 years. Epidemiological observations indicate a clear gender bias, with males being affected at a higher rate than females, often by a ratio of approximately 2:1 to 3:1. Furthermore, while there is no specific geographic "hotspot," the condition is most frequently diagnosed in populations of Northern European descent, though this may reflect historical bias in clinical reporting rather than true genetic susceptibility.

Why is accurate data on Ledderhose disease difficult to obtain?

The primary barrier to understanding the true scope of Ledderhose disease is the high rate of clinical underdiagnosis. Because the nodules are often painless in the early stages, many patients do not report them to a physician. Additionally, because the condition is rare, it is frequently misdiagnosed as other plantar conditions, such as plantar fasciitis, fibromas, or other soft tissue tumors. The 95 individuals currently sharing their experiences on DiseaseMaps.org provide a vital real-world perspective that complements clinical literature, highlighting that even when a condition is "rare" by medical definitions, the impact on the patient community is significant.

Key clinical observations regarding the epidemiology of Ledderhose disease

• Gender Ratio: Clinical studies consistently suggest a male-to-female ratio of 2:1 or higher.


• Age of Onset: Most diagnoses occur in patients between the ages of 40 and 60.


• Co-morbidity: A significant subset of patients with Ledderhose disease also presents with Dupuytren’s contracture (palmar fibromatosis) or Peyronie’s disease.


• Diagnostic Gap: Asymptomatic presentation leads to a likely underestimation of the true prevalence in the general population.

Next steps

• Consult a podiatrist or orthopedic surgeon specializing in foot and ankle disorders for a formal diagnosis.


• Document your symptoms, including the size and location of nodules, to assist your physician in tracking the progression of Ledderhose disease.


• Join the DiseaseMaps.org community to connect with others who have been diagnosed with Ledderhose disease and share insights on management strategies.


• Review your family medical history for related connective tissue disorders, such as Dupuytren’s contracture, as this can be relevant to your clinical profile.
