Plantar Fibroma

While any new growth or mass should be examined by a healthcare provider, a plantar fibroma is a noncancerous (benign) condition. It typically only affects the soft tissues located on the bottom of the foot. Although these growths can cause discomfort, they are not dangerous and do not spread to other parts of the body.

What Is a Plantar Fibroma?

A plantar fibroma is a small, benign growth that forms within the plantar fascia. The plantar fascia is the thick band of connective tissue that supports your foot, stretching from the heel to the base of the toes.

These fibrous nodes usually develop in the arch area and are typically smaller than one inch. While they most often appear in just one foot, it is possible for them to occur in both. These growths are not malignant. In rare instances where a patient develops multiple or more aggressive nodules, a related condition known as plantar fibromatosis may be diagnosed.

What Are the Symptoms of a Plantar Fibroma?

The most prominent sign of a plantar fibroma is the presence of a firm lump in the arch of the foot. To the touch, it may feel like a hard knot or a small marble situated beneath the skin.

Common symptoms include:

• A well-defined, firm mass located in the foot’s arch
• Pain on the sole of the foot, particularly when wearing certain shoes
• The sensation of having a small pebble or stone inside your footwear
• Discomfort or pressure while walking or standing
• A visible bulge on the skin over the arch

Depending on the individual, some people may experience very little pain. Others may find significant discomfort if the fibroma presses against the surrounding tissue or the interior of their shoes. While most remain small, some plantar fibromas can grow to three inches or larger.

What Causes a Plantar Fibroma?

The exact cause of a plantar fibroma is not fully understood. These benign fibrous nodules develop within the plantar fascia, the thick band of tissue that supports the arch of the foot.

Factors that may increase the risk of developing a plantar fibroma include:

• Family history of plantar fibromatosis
• Repetitive stress on the plantar fascia
• Previous foot trauma or injury
• Certain medical conditions
• Certain medications
• Connective tissue disorders

Plantar fibromas can develop in one or both feet and may occur as a single nodule or multiple nodules. While they are not cancerous, they can gradually enlarge and become painful when walking or standing, particularly when pressure is placed directly over the growth.

How Is a Plantar Fibroma Treated?

The majority of cases are handled using conservative management strategies, which may include:

• Anti-inflammatory medications available over-the-counter
• Supportive shoe inserts or custom-molded orthotics
• Offloading pads designed to divert pressure away from the lump
• Targeted stretching exercises
• Topical anti-inflammatory treatments
• Cortisone injections to reduce swelling
• Professional physical therapy

The goal of these conservative options is to minimize pressure on the nodule, making daily activities like standing and walking more comfortable.

Plantar Fibroma Surgery

Surgical intervention to remove a plantar fibroma is generally only recommended if pain persists despite trying conservative treatments.

While less common, surgical options may involve removing just the fibroma or excise a small amount of the surrounding tissue. In very rare cases, a larger section of the plantar fascia may need to be removed.

Patients should be aware that surgery carries a risk of recurrence and can occasionally impact the structure of the foot’s arch. Consequently, surgery is usually reserved for cases where the growth significantly hinders daily functioning.

When Should You See a Foot & Ankle Specialist?

If you are experiencing foot issues, we encourage you to schedule an evaluation with the team at Fox Valley Orthopedics if:

• You discover a new lump or notice a change in the shape of your foot
• You have foot pain that is new or worsening
• Walking has become difficult or uncomfortable

Even though plantar fibromas are benign, any new growth should be professionally assessed to rule out other potential medical conditions.

What Is the Outlook for Plantar Fibromas?

Plantar fibromas are not life-threatening and do not metastasize. Many patients find that they can successfully manage their symptoms through simple, non-invasive treatments. If a fibroma is not causing pain, it typically does not require intervention, and you can continue your usual exercise and sports routines.

If you notice changes in your symptoms, an early evaluation can help ensure you remain active and comfortable over the long term.
