Are you experiencing painful lumps on the bottom of your feet? Let's learn about Plantar Fibromatosis or Ledderhose Disease.

Have you ever felt a lump or bump on the bottom of your foot when you walk or touch it? It feels like a small pea stuck in your shoe? These lumps can sometimes cause pain when you stand or walk. This is the condition we are going to talk about today, called Plantar Fibromatosis , or Ledderhose Disease . This is a rare condition, but it is important to be aware of it.

What is this (Plantar Fibromatosis)?

Simply put, Plantar Fibromatosis is a condition that occurs in the plantar fascia , a thick layer of tissue that supports and protects the sole of your foot. This is where small, hard lumps called plantar fibromas develop on the sole of your foot, especially in the middle of the arch. These can feel like a small lump of clay or a pea. These lumps can sometimes grow very quickly, up to 1 or 2 centimeters in size.

Now you may be wondering if these lumps are cancerous. No, they are not cancerous (benign). This means that they do not spread to other parts of the body. However, they can be quite painful . They can affect your ability to stand and walk, and can also reduce your quality of life. So if you have these symptoms, it is best to see a doctor for advice.

What are the stages of this condition?

There are three main stages of Plantar Fibromatosis. Let's take a look at what they are:

1. The first phase (Proliferative phase): In this phase, there is a type of cell called fibroblasts that makes up the tissue underneath, and the number of those cells increases. However, at this time, there is very little protein called collagen .

2. Active phase: Here, the fibroblasts continue to grow, and the amount of collagen increases. It is during this phase that the nodules we mentioned begin to form.

3. Residual phase: In this phase, fibroblast activity decreases, but collagen production is rapid. This causes scar tissue to form and begin to contract.

What symptoms can you feel?

Ledderhose Disease causes one or more lumps to develop on the bottom of your foot. This can be very uncomfortable and can interfere with your daily activities. Here are some other symptoms of Plantar Fibromatosis:

  • Pain and swelling in the soles of the feet: Pain may occur, especially in the area where the bumps are. This pain may increase when standing or walking.
  • Difficulty standing and/or walking: Some people find it difficult to walk and stand because the bumps cause pain when the soles of their feet touch the ground.
  • Toes curling downward: Sometimes the toes can curl downward, that is, toward the sole of the foot, naturally.
  • Inability to straighten fingers: Once your fingers are bent like that, it can be difficult to straighten them again.

What could be causing this?

Researchers still don't know exactly what causes plantar fibromatosis, but they believe that several factors may contribute to it. These include:

  • Genetics: This means it could be hereditary.
  • Other associated health conditions: For example, it may be associated with conditions such as Dupuytren's contracture (where the fingers bend inward), Peyronie's disease (a condition affecting the penis in men), and knuckle pads .
  • Trauma or injury to the soles of the feet: This condition can also occur due to a severe injury to the soles of the feet.

Who is more likely to develop this? (Risk Factors)

Although this condition (Ledderhose Disease) can develop at any age, it is most common in people between the ages of 30 and 50. Also, some people are more likely to develop it. For example:

  • For those of Northwestern European descent.
  • Men develop it a little more than women.
  • Smokers are also at higher risk.

In addition, this condition (Plantar Fibromatosis) is more common in people with certain other diseases. Consider these things:

  • For those who drink excessively (Alcohol use disorder)
  • For those with diabetes (Diabetes Mellitus)
  • For those with Dupuytren contracture (a condition that causes the fingers to bend inward) (this is also somewhat similar to this disease)
  • For those with epilepsy
  • For those with frozen shoulder
  • For those with knuckle pads
  • For those with a condition called Peyronie's disease

How does a doctor diagnose this?

When you go to see a doctor with a lump on the bottom of your foot, how exactly does he diagnose it (Plantar Fibromatosis)?

First, the doctor will ask you a few questions. Think about things like:

  • 'Does anyone in your family have these kinds of plantar warts?' (That is, see if there is a hereditary link)
  • 'Have you ever had a condition similar to this (Dupuytren contracture) before?'
  • 'Do you have diabetes?'
  • 'Do you have epilepsy?'

After asking these questions, the doctor will examine your leg carefully. Then, they will pay attention to the following:

  • The sole of the foot is checked for swelling, bruising, lumps, wounds, or other deformities.
  • They note whether there are any painful areas on the soles of the feet and heels, or areas that hurt when pressed.
  • The Achilles tendon at the back of your ankle and the muscles around it will be examined.
  • The range of motion of the foot is checked.
  • You will be asked to walk for a short distance and your feet and ankles will be monitored for movement.

Tests to confirm the disease

After that, the doctor may also perform some tests to confirm the exact diagnosis.

  • Ultrasound: After reviewing your symptoms and medical history, if your doctor suspects that you may have Plantar Fibromatosis, they may perform an ultrasound to confirm the diagnosis.
  • Magnetic Resonance Imaging (MRI) scan: Sometimes, when the disease is more severe, the lumps may have spread into the underlying tissue. However, this is very rare. An MRI scan can help determine how severe your condition is.
  • Biopsy: This involves taking a small piece of tissue, cells, or fluid from the lump on your bottom and testing it. A biopsy can confirm that the lump is not cancerous.

What is the treatment for this? (Treatment)

Okay, now let's see what treatments are available for this (Plantar Fibromatosis). In the early stages of this, doctors usually try to provide relief with mild, simple treatments.

Early treatment

  • Ice application: Place an ice pack wrapped in a clean cloth on the painful area of ​​the sole of the foot for about 20 minutes. You can do this three to four times a day.
  • Medications: You can buy over-the-counter pain relievers, or nonsteroidal anti-inflammatory medications (NSAIDs) (such as aspirin, ibuprofen, or naproxen), to reduce pain and swelling. However, it's best to consult a doctor.
  • Orthotics: Over-the-counter (OTC) shoe inserts or custom orthotics can help. You can cut holes in your shoe inserts to fit over the bumps. This will reduce the pressure on the bumps.
  • Massage: Gently massage the soles of your feet . But don't touch the bumps , as doing so can increase the pain.
  • Physical therapy: You can work with a physical therapist to do exercises that stretch and strengthen the connective tissues in the sole of the foot.

Remember: If the pain does not subside after a few months with these simple treatments, you should definitely see a doctor again.

Treatment if the pain does not subside

If the pain doesn't subside after a few months of simple treatments, your doctor may suggest other treatments, such as:

  • Intralesional steroids: Steroid injections injected directly into the lump.
  • (Verapamil) Medication: This is sometimes given as an ointment.
  • Radiation therapy:
  • Extracorporeal shock wave therapy (ESWT): A treatment using high-energy sound waves.
  • (Tamoxifen) medicine:
  • (Sorafenib) medicine:
  • Collagenase injection: An injection containing an enzyme that breaks down collagen.
  • Surgery: Surgery is usually considered as a last resort if all other treatments fail, as these tumors are more likely to recur.

When exactly should I see a doctor?

If you have any of these symptoms, definitely make an appointment to see a doctor:

  • If you see lumps in the middle of the sole.
  • If you feel like you have difficulty standing or walking.
  • If you have long-term pain in your lower back.
  • If it is difficult to straighten your toes, or if they seem to be bent downwards.

What questions can you ask the doctor?

When you see your doctor, don't forget to ask any questions you have about this condition. For example:

  • 'Doctor, what activities should I avoid? For how long?'
  • 'What can I do to control this pain?'
  • 'What kind of treatment does the doctor recommend for me?'

What can be expected with this situation?
