Foot and Ankle Dermatology

Skin and nail problems are not always simple maintenance issues. Painful calluses often reflect structural overload or deformity. They may be caused by underlying deformities such as Hammertoe or Hallux valgus. Thick fungal nails may become painful enough to require surgical removal. Suspicious skin lesions may need biopsy or excision. In patients with diabetes or poor circulation, skin breakdown may become limb-threatening and require urgent limb preservation care.

At Seattle Foot and Ankle Center, Dr. John Hoy focuses on identifying the cause of skin and nail problems—not simply trimming or reducing them over and over. Treatment may include medical therapy, biopsy, office procedures, corrective surgery, or diabetic limb preservation.

Dr. Hoy provides personalized care to restore healthy skin, relieve discomfort, and prevent recurring problems. If you’ve noticed a difference in the skin on your feet or ankles, make an appointment with our office today.

Foot and Ankle Problems Deserve Specialist Evaluation Early

Many changes involving the toenails or skin of the feet appear to be simple dermatologic problems but may have several possible causes. Thick nails, discoloration, ingrown toenails, chronic skin irritation, or recurring infections can result from fungal infections, mechanical pressure, circulation problems, trauma, inflammatory skin diseases, or underlying medical conditions such as diabetes.

The foot and ankle are an anatomic region, and podiatry is the specialty dedicated to that region. A foot and ankle physician evaluates the entire foot rather than focusing only on the skin or nail. This allows treatment to address the underlying cause in addition to the visible symptoms. A foot and ankle physician can first evaluate the problem, establish the diagnosis, and determine the appropriate course of care. When additional expertise is needed, that care can be coordinated as part of the treatment plan.

While dermatologists are experts in diseases of the skin, many foot conditions also involve biomechanics, footwear, circulation, or structural abnormalities. When necessary, coordination between podiatry and dermatology provides the most comprehensive care.

When problem persists despite initial treatment, the diagnosis and contributing factors may need to be reassessed.

Common Foot and Ankle Skin Conditions

1. Suspicious Skin Lesions & Biopsy

Not all skin lesions are warts. Persistent lesions may require biopsy or surgical evaluation. Skin lesions on the feet and ankles can range from benign growths to serious conditions such as skin cancer. Any foot lesion that changes in size, shape, or color, bleeds, or does not heal should be evaluated promptly. New or changing lesions—especially those involving or beneath the toenail—require careful evaluation to rule out infection, chronic pressure injury, or skin cancer. Dr. John Hoy performs careful skin evaluations and in-office biopsies when necessary to establish a diagnosis and guide treatment. Early identification is important for both effective treatment and peace of mind.

2. Painful Fungal Nails

Onychomycosis is a common cause of thickened, discolored, brittle, and painful nails. What may begin as a cosmetic problem can progress into pressure pain, shoe irritation, secondary bacterial infection, or ulceration—especially in patients with diabetes or poor circulation. Treatment may include laboratory testing, prescription antifungal medication, surgical thinning, or partial or complete nail removal when the nail becomes too painful or severely damaged.

3. Ingrown Nails

Ingrown toenail occurs when the nail edge grows into the surrounding skin, causing pain, swelling, redness, and infection. Left untreated, ingrown nails can lead to abscesses, chronic infections, and in at-risk patients even deeper skin or bone infections. Treatment ranges from conservative care to permanent surgical correction of the nail border to prevent recurrence.

4. Plantar Warts

Plantar warts are caused by the human papillomavirus (HPV) and often appear as painful thickened lesions on the bottom of the foot. They can be mistaken for calluses and may become painful with walking or standing. Treatment may include medical therapy, cryotherapy, chemical destruction, or surgical excision depending on the severity and how resistant the wart has become. Persistent warts often require more than over-the-counter treatment.

5. Painful Calluses from Deformity

Calluses often form from excessive pressure over bony deformities such as Hammertoe, Hallux valgus, or prominent metatarsal bones. While trimming may offer temporary relief, recurrent painful calluses usually indicate an underlying mechanical problem. Proper diagnosis may reveal the need for orthotics, shoe changes, or corrective surgery to relieve pressure and prevent ongoing recurrence.

6. Diabetic Ulcers & Skin Breakdown

For patients with diabetes, even minor skin injuries can quickly become serious. Pressure points, thick nails, calluses, and unnoticed wounds may progress into infection, tissue loss, or amputation risk. Dr. Hoy provides diabetic wound care, offloading, infection management, and limb preservation strategies designed to promote healing and prevent complications. Early treatment is critical for saving both tissue and function.

7. Skin Infections

Skin infections such as cellulitis, abscesses, fungal infections, or infected wounds can cause redness, swelling, warmth, drainage, and significant pain. Prompt diagnosis is important to determine whether the infection is superficial or involves deeper tissues. Treatment may include antibiotics, drainage procedures, wound care, and surgical debridement when necessary.

8. Athlete’s Foot

Tinea pedis is a fungal infection that commonly causes itching, redness, peeling, cracking, and burning between the toes or on the soles of the feet. Left untreated, athlete’s foot can spread to the nails, lead to skin breakdown, and increase the risk of bacterial infection. Treatment focuses on antifungal medications, skin care, and prevention strategies to avoid recurrence.

Tips for Healthy Foot and Ankle Skin

  • Wear breathable, properly fitting shoes.
  • Keep feet clean and dry, especially between toes.
  • Moisturize regularly to prevent dryness and cracking.
  • Inspect feet daily for blisters, cuts, unusual spots, or lesions.
  • Avoid walking barefoot in public areas to prevent infections.
  • Seek prompt evaluation for any suspicious or rapidly changing skin areas.

Medical & Surgical Nail Care

Nail conditions can be painful, infected, or functionally limiting. Some require medical treatment, while others may need surgical correction or removal.  There are ten nails on the average human foot, each of which can cause problems.  Common conditions seen include ingrown nails, thick nails, long nails, fungal nails.  Ingrown nails can lacerate the skin and cause skin and bone infections.  Thick nails can cause ulcerations or sores of the nail bed.  Long nails can lacerate the skin of adjacent toes or can pull off and cause an open wound or blood blister of the nail bed.  Fungal nails can develop into an athlete’s foot infection.  A foot and ankle surgeon can diagnose the cause of toenail problems and can recommend treatments.  Podiatrists treat the above and other conditions by medical and surgical means.

Thick, Discolored, or Painful Toenails (Is It Really Fungus?)

Many people assume that a thick, yellow, brittle, or misshapen toenail is caused by fungus. While fungal infection (onychomycosis) is common, it is far from the only cause. Nail trauma, years of shoe pressure, previous injuries, psoriasis, chronic nail polish use, inflammatory skin conditions, and permanent damage to the nail root can all produce nails that closely resemble fungal infection.

Because treatment depends on the cause, the first step is making the correct diagnosis—not simply prescribing medication. Dr. John Hoy may recommend a laboratory examination of a nail specimen to confirm whether fungus is actually present before discussing treatment options.

If Fungus Is Confirmed

Treatment depends on your overall health, the severity of the infection, and your goals.

  • Oral antifungal medication offers the highest chance of eliminating the infection but requires laboratory confirmation of fungus before treatment. Blood tests are also typically required to ensure the medication can be taken safely.
  • Topical antifungal medications may help suppress fungal growth in some patients but often do not eliminate established infections in thick toenails because they penetrate the nail poorly.
  • Nail debridement (thinning) can reduce pressure and discomfort from a thick nail but does not cure the underlying fungal infection.
  • Partial or complete nail removal may be recommended when a nail is severely thickened, painful, repeatedly ingrown, or extensively damaged.

If It Is Not Fungus

If laboratory testing does not show fungus, treatment for fungal infection is unlikely to help. Depending on the underlying cause, the nail changes may be due to previous trauma, nail matrix injury, psoriasis, or another condition. Some nail deformities are permanent because the nail-producing tissue has been damaged.

What We Do Not Offer

Seattle Foot & Ankle Center does not offer laser treatment for fungal toenails. Current medical evidence has not shown laser therapy to provide consistently reliable cure rates comparable to appropriately selected oral antifungal treatment.

Our goal is to accurately diagnose the cause of your nail changes, relieve pain when present, reduce the risk of infection or skin breakdown, and recommend treatment that is medically appropriate—not simply cosmetic.

Thick nails, wounds, and infections may increase the risk of ulceration and limb loss. Dr. Hoy provides medical and surgical care focused on prevention, wound healing, and limb preservation.


Frequently Asked Questions About Foot and Toenail Skin Problems

What types of skin conditions affect the feet?

Many different skin conditions can affect the feet and ankles. Some of the most common include:
Athlete’s foot (fungal infections)
Plantar warts
Corns and calluses
Blisters and friction injuries
Dry or cracked skin
Bacterial skin infections
Fungal toenail infections
Suspicious moles or skin lesions
A podiatrist specializes in diagnosing and treating these conditions to relieve symptoms and prevent complications.

What causes athlete’s foot?

Athlete’s foot is a fungal infection that thrives in warm, moist environments such as shoes, locker rooms, and public showers. It often spreads through direct contact with contaminated surfaces.
Common symptoms include itching, peeling skin, redness, and cracking between the toes. Treatment typically involves antifungal medications and strategies to keep the feet dry and protected.

What are plantar warts and how are they treated?

Plantar warts are caused by the human papillomavirus (HPV) and appear on the soles of the feet. They may feel like small, rough growths and can cause discomfort when walking.
Treatment options may include:
Cryotherapy (freezing the wart)
Topical medications
Minimally invasive removal procedures
A podiatrist can determine the best treatment depending on the size and location of the wart.

How can I tell if I have a fungal toenail infection?

Fugal toenail infections often cause the nail to become:
Thickened or brittle
Yellow, brown, or discolored
Distorted or crumbly
Painful or difficult to trim
Because topical creams rarely penetrate the nail effectively, professional diagnosis and treatment from a podiatrist are usually necessary.

How are fungal toenail infections treated?

Treatment options depend on the severity of the infection. Dr. Hoy may recommend:
Prescription oral antifungal medications
Laboratory testing to confirm fungal infection
Professional nail debridement (trimming and thinning thick nails)
Partial or complete nail removal for severe infections
Proper diagnosis is important to ensure the correct treatment is used.

When should I see a podiatrist for foot skin problems?

You should schedule an appointment if you notice:
Persistent itching, redness, or peeling skin
Thick or discolored toenails
Painful warts or skin growths
Blisters, sores, or wounds that don’t heal
Unusual moles or rapidly changing skin spots
Early treatment can prevent minor skin problems from becoming painful infections.

Can foot skin conditions become serious?

Yes. While many foot skin conditions are minor, untreated infections can spread and cause complications. People with diabetes, poor circulation, or nerve damage are especially at risk for serious infections and should seek prompt medical care for any skin changes on their feet.

How can I prevent foot and toenail skin problems?

Good foot hygiene and preventive care can reduce your risk of infections and skin issues. Helpful tips include:
Keep feet clean and dry
Wear breathable, properly fitting shoes
Change socks daily
Avoid walking barefoot in public areas
Trim toenails straight across
Inspect your feet regularly for changes
Regular podiatry visits can also help detect problems early.

Can a podiatrist check for skin cancer on the feet?

Yes. Skin cancer can develop on the feet and ankles, including melanoma and other types of skin cancer. Warning signs may include:
New or changing moles
Dark spots or irregular pigmentation
Lesions that bleed or do not heal
Rapidly changing skin areas
Dr. Hoy performs careful evaluations and can perform biopsies or refer patients to specialists when necessary.

What nail problems can a podiatrist treat?

Podiatrists treat many types of toenail problems, including:
Ingrown toenails
Thick or painful nails
Fungal nail infections
Traumatic nail injuries
Nail deformities
Professional nail care is especially important for patients with diabetes, neuropathy, or circulation problems to prevent complications.

Do calluses always need trimming?

No. Recurrent calluses may signal an underlying deformity that may need correction.

Can fungal nails be surgically removed?

Yes. Painful or severe fungal nails may require partial or complete removal.

When should a skin lesion be biopsied?

If it changes, bleeds, enlarges, or looks suspicious.

Can foot wounds lead to amputation?

Yes, especially in diabetic patients. Early limb preservation treatment is critical.
