What is Keratolysis? Pitted Keratolysis

Pitted keratolysis is a bacterial skin infection that affects the feet. It is characterized by the presence of small, shallow pits on the soles of the feet, accompanied by an unpleasant odour. While it is not a serious condition, it can be embarrassing and uncomfortable.

What is Keratolysis?

Keratolysis is a medical condition characterized by the presence of small, superficial pits or depressions in the skin. It is caused by excessive sweating or exposure to moisture, which softens the skin and allows it to be easily abraded. The condition is most commonly seen on the palms of the hands and the soles of the feet, and is often associated with other skin conditions such as athlete's foot or eczema. Treatment typically involves keeping the affected area clean and dry, and using topical medications or keratolytic agents to remove the damaged skin. In severe cases, more aggressive treatment such as laser therapy or surgery may be necessary.

What is Pitted Keratolysis?

Pitted keratolysis is a bacterial skin infection that influences the soles of the feet and presents with small, shallow pits or depressions in the skin. It is caused by a group of bacteria called Corynebacterium and occurs more commonly in people who sweat excessively, wear tight or non-breathable shoes, and have poor foot hygiene. Symptoms include foul odour, excessive sweating, and a burning or itching sensation on the feet. Treatment involves keeping the feet clean and dry, using antibacterial soaps, and applying topical antimicrobial agents. In severe cases, oral antibiotics may be required.

What are the Causes of Pitted Keratolysis?

Pitted Keratolysis is a bacterial skin infection that is caused by several types of bacteria such as Corynebacterium, Dermatophilus, and Streptomyces. These bacteria thrive in warm, moist environments such as sweaty feet, which is why pitted keratolysis is often found on the soles of the feet. The bacteria produce enzymes that break down the skin's top layer, resulting in small, shallow pits or depressions in the affected area. Certain factors can increase the risk of developing pitted keratolysis, such as excessive sweating, wearing tight or non-breathable footwear, walking barefoot in damp public areas, and having a weakened immune system.

Pitted Keratolysis Treatment

Pitted keratolysis is a bacterial skin infection that impacts the soles of the feet, resulting in small, shallow pits and foul odour. The condition is caused by a specific group of bacteria, including Corynebacterium and Dermatophilus congolensis, that thrive in warm, moist environments.

There are several treatment options for pitted keratolysis, including:

1. Topical antibiotics: Topical antibiotics such as erythromycin, clindamycin, and fusidic acid can be applied directly to the affected areas to kill the bacteria causing the infection.
2. Antiperspirants: Since pitted keratolysis thrives in moist environments, antiperspirants can help reduce the amount of sweat produced by the feet, thereby reducing the conditions that encourage bacterial growth.
3. Foot powders: Powders containing aluminum chloride or zinc oxide can help absorb excess moisture and prevent the growth of bacteria.
4. Soaking the feet: Soaking the feet in warm water with antibacterial agents such as potassium permanganate or chlorhexidine can also help kill the bacteria.
5. Good foot hygiene: Keeping the feet clean and dry by washing them regularly with soap and water, changing socks and shoes frequently, and using open-toed shoes can also help prevent the recurrence of pitted keratolysis.

It is important to consult a healthcare provider for proper diagnosis and treatment of pitted keratolysis. In severe cases, oral antibiotics may be necessary.

Pitted Keratolysis Treatment Cream

There are several over-the-counter and prescription creams that may help with the treatment of pitted keratolysis. Some of the common creams that can be used include:

1. Clindamycin Cream: Clindamycin cream is a prescription cream that is used to treat bacterial infections. It is effective in treating pitted keratolysis as it helps to kill the bacteria that cause the condition.
2. Benzoyl Peroxide Cream: Benzoyl peroxide cream is an over-the-counter cream that is used to treat acne. It can also be used to treat pitted keratolysis as it has antibacterial properties that can help to kill the bacteria that cause the condition.
3. Erythromycin Cream: Erythromycin cream is a prescription cream that is used to treat bacterial infections. It is effective in treating pitted keratolysis as it helps to kill the bacteria that cause the condition.
4. Tea Tree Oil Cream: Tea tree oil cream is an over-the-counter cream that is known for its antibacterial properties. It can be used to treat pitted keratolysis as it helps to kill the bacteria that cause the condition.

It is important to note that the effectiveness of these creams may vary from person to person, and it is recommended to consult a dermatologist for proper diagnosis and treatment plan.

How is Pitted Keratolysis Diagnosed?

Pitted keratolysis is diagnosed based on the following steps:

1. Visual examination: The condition is often diagnosed based on its distinctive appearance on the skin, characterized by crater-like pits and malodor.
2. Medical history: Your healthcare provider will ask about your medical history, including any risk factors like excessive sweating, wearing tight shoes with minimal airflow, or having a condition that causes excessive sweating.
3. Clinical features: The appearance of the pits may be amplified when feet are wet, and there may be associated features like hyperhidrosis, slimy texture of the skin, and malodorous feet.
4. Exclusion of other conditions: Your healthcare provider might offer tests to rule out similar conditions, such as erythrasma or tinea pedis.
5. Additional tests: In some cases, skin scrapings may be taken to exclude a fungal infection, and a skin biopsy with histopathology may be performed if there is diagnostic uncertainty.

The diagnosis is often clinical given its distinctive appearance and malodor.

How to Treat Pitted Keratolysis at Home?

Pitted keratolysis is a bacterial skin infection that affects the soles of the feet and can be treated with a combination of prescription medication and good foot hygiene practices. While it is essential to seek medical attention from a dermatologist or podiatrist for proper diagnosis and treatment, there are also some tips to manage and prevent pitted keratolysis at home. Here are some tips:

1. Keep feet clean and dry: Wash feet daily with soap and water and dry them thoroughly, especially in between the toes. Avoid keeping the feet damp for long periods of time.
2. Wear breathable footwear: Choose shoes made of breathable materials such as leather, canvas, or mesh. Avoid shoes made of synthetic materials, which trap moisture and promote bacterial growth.
3. Change socks frequently: Wear clean socks every day, and change them if they become damp or sweaty.
4. Use antiperspirant: Apply an antiperspirant to the soles of the feet to reduce sweating and inhibit bacterial growth.
5. Apply topical medication: Over-the-counter antifungal creams, such as clotrimazole, miconazole or tolnaftate, can help treat pitted keratolysis. Apply as directed by a healthcare professional.
6. Use foot powder: Dust feet with an antifungal foot powder to absorb moisture and prevent bacterial growth.
7. Soak feet in tea tree oil: Soaking feet in a warm water bath with a few drops of tea tree oil can help reduce bacterial growth and odour.

It is important to note that these tips may help manage and prevent pitted keratolysis, but they are not a substitute for medical treatment. If you suspect you have pitted keratolysis, it is significant to seek medical attention for proper diagnosis and treatment.

If your pitted keratolysis does not improve with these measures, consult with a healthcare professional for further treatment options.

Early Stage Pitted Keratolysis

Early stage Pitted Keratolysis can be treated with the following measures:

1. Keep the affected area clean and dry: Wash the affected area with soap and water, then pat it dry. Avoid wearing tight shoes or socks that may cause sweating and aggravate the condition.
2. Use antiperspirant: Apply an antiperspirant containing aluminum chloride to the affected area. This helps reduce sweating and control the growth of bacteria.
3. Apply topical antibiotics: Topical antibiotics like erythromycin, clindamycin, or mupirocin can be used to treat pitted keratolysis. They work by killing the bacteria that cause the condition.
4. Use keratolytic agents: Keratolytic agents like salicylic acid, urea, and ammonium lactate can be used to help remove the thickened, dead skin that is a hallmark of pitted keratolysis. These agents work by breaking down the keratin in the skin.
5. Wear open-toe shoes: Wearing open-toe shoes or sandals can help keep the affected area dry and promote air circulation, which can help control the growth of bacteria.
6. Change shoes and socks frequently: Changing shoes and socks frequently can help reduce the amount of sweat and bacteria on your feet.

It is important to note that these measures may not be effective for severe or advanced cases of pitted keratolysis, and that medical intervention may be necessary. If your symptoms do not improve after several days of home treatment, or if your condition worsens, consult a doctor or dermatologist for further evaluation and treatment.

Can pitted keratolysis go away on its own?

In mild cases, pitted keratolysis can resolve on its own by keeping the feet clean and dry. But the malodor and infections tend to persist or recur without treatment with antibacterial agents in most cases.

Is pitted keratolysis itchy?

The small eroded pits and patches due to pitted keratolysis are usually not itchy. But associated bacterial or fungal infection can sometimes cause mildly itchy skin between the toes along with foul smell.

Does pitted keratolysis spread?

If left untreated for long, the anaerobic bacteria can spread leading to more skin erosions and bad odor. Timely topical antibiotic treatment helps restrict its contagious spread.

Can you spread pitted keratolysis to others?

Yes, there is a small chance for spreading the bacteria causing pitted keratolysis to others through shared clothing or footwear. Treating active infections using antibacterial creams reduces transmission risks substantially.
