DERMATOLOGY
The skin is the body’s first line of defence, and when it comes to the feet, it faces constant pressure, friction, moisture, and exposure to infections. At Blackrock Podiatry, we specialise in diagnosing and managing a wide range of dermatological conditions affecting the feet and lower limbs.
Common Skin Conditions We Treat Include:
-
Corns and calluses
-
Fungal infections (Athlete’s foot, onychomycosis)
-
Viral warts (verrucae)
-
Psoriasis and eczema of the feet
-
Pitted keratolysis
-
Hyperhidrosis and anhidrosis (sweating disorders)
-
Ulcers and skin breakdown in diabetic or vascular patients
-
Pigment changes, rashes, and suspicious lesions
Why Dermatology Matters in Podiatry:
Foot skin conditions are often chronic, recurring, and can easily go unnoticed until they become painful or infected. Our podiatrists are trained to spot early signs of dermatological and systemic issues, offering evidence-based treatments and preventive care tailored to each patient’s needs.
Whether it’s a stubborn rash, cracked heels, or an unexplained lesion, we provide expert care with the latest techniques in foot dermatology.
VENOUS ULCERATION
Venous insufficiency is characterised by discolouration and varicose eczema on the lower leg
Ulcers follow minor trauma
Venous ulcer healing is protracted
PLANTAR PUSTULOSIS / DERMATOSIS
Plantar Pustulosis is a form of psoriasis seen on the feet.
Juvenile plantar dermatosis is a contact dermatosis caused by synthetic footwear.
Erythematous lesions are managed with steroids and emollients.
Fungal infections of the skin and nails are common, affecting 10% of the population.
They are caused by dermatophyte infections.
Skin and nail infections are often found together
Infections of the skin require advise and astringents or if persisent azoles or allylamines.
DERMATOLOGY
PITTED KERATOLYSIS (SWEATY FEET)
Pitted Keratolysis is a bacterial skin condition commonly associated with excessive sweating (hyperhidrosis). It typically affects the soles of the feet and areas between the toes, leading to small depressions or pits in the skin, often accompanied by odour and discomfort.
When sweat production by the eccrine glands is either too high (hyperhidrosis) or too low (anhidrosis), it can alter the skin’s mechanical strength. This may result in:
-
Moist fissures (especially between the toes)
-
Dry fissures (commonly around the edges of the heels)
If left untreated, these skin changes can lead to secondary bacterial or fungal infections, particularly when the skin barrier is compromised.
Management of Hyperhidrosis Includes:
-
Wearing sweat-absorbing insoles
-
Rotating and airing footwear regularly
-
Applying astringents, antiperspirants, and deodorants specifically formulated for feet.

Chilblains & Raynaud's Syndrome
Chilblains are an exaggerated skin response to cold, often appearing as red, swollen, itchy patches, and sometimes painful lesions on the toes or fingers. They are commonly seen in individuals with Raynaud’s syndrome, a vasoconstrictive condition that reduces blood flow to the extremities, typically triggered by cold or stress. Raynaud’s most commonly affects middle-aged women and is often associated with autoimmune conditions, such as scleroderma.
Chilblain Management Includes:
-
Avoiding cold exposure and sudden temperature changes
-
Wearing insulated footwear and using thermal inserts or padding to retain warmth
-
Applying topical ointments that cool, soothe, and reduce inflammation
-
When lesions are open or broken, using protective dressings and paddings to prevent infection and support healing
-
In more persistent or severe cases, vasodilator medications may be prescribed to improve circulation
Early intervention and appropriate protection can significantly reduce discomfort and the risk of complications.
1. Plantar Pustulosis
Plantar pustulosis is a chronic form of psoriasis that appears on the soles of the feet. It is characterised by sterile pustules, redness, and scaling. This condition can be painful and may flare periodically. Treatment often includes topical steroids, emollients, and sometimes phototherapy or systemic medications, depending on severity.
2. Juvenile Plantar Dermatosis
This condition typically affects children and adolescents, presenting as shiny, red, and cracked skin on the weight-bearing areas of the feet. It is often caused by prolonged exposure to moisture, friction, and synthetic footwear. Management includes avoiding irritants, using moisture-wicking socks, and applying emollients to maintain skin hydration.
3. Erythematous Lesions
Erythematous (red) skin lesions on the feet may result from a variety of underlying conditions, including eczema, dermatitis, or infections. These are typically managed with topical corticosteroids to reduce inflammation, alongside emollients to restore the skin barrier.
Venous Eczema (Stasis Dermatitis)
Venous eczema is a skin condition commonly associated with venous hypertension—a condition where poor circulation in the lower legs leads to increased pressure in the veins.
This condition often presents with:
-
Brown staining or discolouration of the skin (from blood pigment leakage)
-
Pain, itching, dryness, and scaliness
-
Swelling due to poor fluid drainage
-
Thin, fragile skin texture, prone to breakdown and venous ulceration
-
White, patchy scars (known as atrophie blanche) in chronic cases
Venous eczema not only causes discomfort but can also be an early warning sign of more serious vascular issues. Proper management—including compression therapy, skincare, and medical assessment—is essential to prevent complications.
