Q: Unusual Bumps on Heels: Causes and Treatment Options Explained

There is a strange growth on the heel?

Hello Dr.
Chang, I would like to ask you a question: I have developed small blisters on the heels of both feet, which later merged into large pus-filled lesions.
The surrounding area is somewhat itchy, but the pus-filled areas are painful when touched.
They look quite alarming due to their size.
As the pus gradually gets absorbed by the body, it turns into a red-black, hard callus-like protrusion, and I still feel an itchy sensation.
The skin on my heels is starting to thicken and appears to be peeling.
During this time, I have been applying antifungal cream (thinking it was athlete's foot), but it has been completely ineffective.
What could be causing this? Is it related to my poor immune system (as I have never had this issue before)? Or does this have nothing to do with dermatology? Which specialist should I consult? Thank you!

Hello, Xiao Juan: The symptoms you described are consistent with dyshidrotic eczema (pompholyx).
The causes can be attributed to an atopic constitution (such as asthma, allergic rhinitis, allergic conjunctivitis, or dermatitis) or an allergic reaction due to a tinea pedis (athlete's foot) infection, or irritation from external cleaning agents.
The treatment involves the use of potent topical corticosteroids, and in severe cases, oral corticosteroids may be prescribed.
Additionally, using astringents (such as aluminum salts, acetone, potassium permanganate, or tea infusion) for soaking can effectively help dry out the blisters.
If these methods are ineffective, localized phototherapy (UV therapy) can be considered.
Once the blistering phase has ended and the peeling stage begins, keratolytics such as urea or salicylic acid can be applied.
It is advisable to consult a dermatologist for treatment, but it is important to be patient and not to discontinue treatment prematurely.

More Info

Unusual bumps on the heels, especially those that start as small blisters and then merge into larger pus-filled areas, can be concerning and may indicate a variety of underlying conditions. Based on your description, it seems like you are experiencing a painful and itchy condition that has progressed to the formation of hard, red-black lesions on your heels. Here’s a detailed explanation of potential causes and treatment options.

Possible Causes
1. Infection: The presence of pus suggests a possible bacterial infection, such as a skin abscess. This can occur when bacteria enter through a break in the skin, leading to localized inflammation and pus formation. Conditions like cellulitis could also be a factor.

2. Fungal Infections: While you mentioned using antifungal cream, it’s important to note that not all skin conditions respond to antifungal treatments. Conditions like tinea pedis (athlete's foot) can cause blisters and may sometimes be misdiagnosed. However, if the antifungal treatment did not yield results, this may not be the primary issue.

3. Dermatitis: Contact dermatitis or allergic reactions can cause itchy, blistering skin. If you have come into contact with an irritant or allergen, this could lead to the symptoms you are experiencing.

4. Autoimmune Conditions: Certain autoimmune disorders can manifest as skin lesions. Conditions like pemphigus or bullous pemphigoid can cause blisters and require specific treatments.

5. Immune System Issues: You mentioned having a compromised immune system. This can increase susceptibility to infections and may lead to more severe manifestations of skin conditions.

Treatment Options
1. Medical Evaluation: It is crucial to see a healthcare provider, preferably a dermatologist, who can accurately diagnose the condition. They may perform a physical examination, take a culture of the pus, or conduct a biopsy if necessary.

2. Antibiotics: If a bacterial infection is confirmed, oral or topical antibiotics may be prescribed to clear the infection.

3. Topical Treatments: Depending on the diagnosis, topical corticosteroids may help reduce inflammation and itching if dermatitis is suspected.

4. Wound Care: Keeping the area clean and covered can prevent further infection. If there are open sores, proper wound care is essential.

5. Immune Support: If your immune system is compromised, addressing the underlying cause and improving your overall health may help in managing skin conditions.

6. Avoid Self-Medication: Since the antifungal treatment did not work, it is advisable to avoid further self-medication without professional guidance, as this could worsen the condition.

When to Seek Help
If the bumps are painful, spreading, or accompanied by fever, it is important to seek medical attention promptly. Additionally, if you notice any signs of systemic infection (such as increased redness, warmth, swelling, or drainage), you should seek immediate care.

Conclusion
In summary, the unusual bumps on your heels could be due to a variety of causes, including infections, dermatitis, or autoimmune conditions. Given the complexity of skin conditions and the potential for complications, it is essential to consult with a dermatologist for a thorough evaluation and appropriate treatment. Early intervention can lead to better outcomes and prevent further complications.
