Crusted scabies

My face tends to be oily, and I have always suspected that I have acne.
I often get raised bumps on my face that seem to have something inside.
When I try to squeeze them, they feel like a mix of blackheads and flesh, and they are difficult to heal without extraction.
My face looks like it has multiple acne lesions.
Recently, I consulted a doctor who diagnosed it as crusted papular dermatitis and I underwent cryotherapy.
What are the causes of crusted papular dermatitis? (I didn't ask in detail that day) How can I prevent it? Also, how can I minimize scars after cryotherapy? Thank you.

Hello, sir: What you may be referring to is "nodular prurigo." The formation of nodular prurigo is quite complex and is associated with several factors: 1.
A more sensitive constitution, 2.
Sensitive skin, and 3.
Exposure to allergens, which may include seasonal factors, airborne pollutants, and other irritants, leading to a series of reactions.
Therefore, prevention can be challenging.
It is advisable to limit the intake of high-fat and high-calorie foods, increase the consumption of natural high-fiber foods, maintain a regular exercise routine, avoid staying up late, and minimize exposure to dirty environments.
Additionally, it is normal to experience pigment deposition after cryotherapy, which will fade over time, so there is no need to worry.
Wishing you a speedy recovery.

More Info

Crusted scabies, also known as Norwegian scabies, is a severe form of scabies characterized by the presence of thick crusts of skin that are infested with a large number of mites. This condition is often seen in individuals with weakened immune systems, such as those with HIV/AIDS, elderly patients, or individuals with other underlying health issues. Understanding the causes, prevention strategies, and scar treatment options for crusted scabies is essential for effective management and recovery.

Causes of Crusted Scabies
Crusted scabies is caused by the Sarcoptes scabiei mite, which burrows into the skin, leading to intense itching and inflammation. In typical scabies, a small number of mites can cause significant symptoms, but in crusted scabies, the immune response is inadequate, allowing the mites to proliferate uncontrollably. Factors that may contribute to the development of crusted scabies include:
1. Immunosuppression: Individuals with compromised immune systems are more susceptible to severe infestations.

2. Poor Hygiene: Lack of proper hygiene can facilitate the spread of mites.

3. Close Living Conditions: Crowded living situations, such as nursing homes or shelters, can increase the risk of transmission.

4. Underlying Skin Conditions: Conditions that compromise the skin barrier can also predispose individuals to scabies.

Prevention of Crusted Scabies
Preventing crusted scabies involves several strategies:
1. Good Hygiene Practices: Regular bathing and maintaining clean skin can help reduce the risk of infestation.

2. Avoiding Close Contact: Limiting close physical contact with individuals known to have scabies can prevent transmission.

3. Treatment of Infected Individuals: Prompt treatment of anyone diagnosed with scabies is crucial to prevent outbreaks.

4. Environmental Control: Washing bedding, clothing, and towels in hot water and drying them on high heat can kill mites and prevent reinfestation.

Scar Treatment After Cryotherapy
Cryotherapy is a treatment option that involves freezing the affected skin to destroy abnormal tissue. While effective for various skin conditions, including crusted scabies, it can sometimes lead to scarring. Here are some strategies to help minimize and treat scars after cryotherapy:
1. Moisturization: Keeping the treated area well-moisturized can promote healing and reduce the appearance of scars. Use a gentle, fragrance-free moisturizer.

2. Sun Protection: Protecting the area from sun exposure is crucial, as UV rays can darken scars. Use sunscreen with a high SPF on the treated area when exposed to sunlight.

3. Silicone Gel Sheets: These can be applied to the scarred area to help flatten and soften scars over time.

4. Topical Treatments: Over-the-counter creams containing ingredients like vitamin E, aloe vera, or silicone can aid in scar healing.

5. Consulting a Dermatologist: If scars persist or are concerning, consulting a dermatologist for advanced treatments such as laser therapy or chemical peels may be beneficial.

In summary, crusted scabies is a serious condition that requires prompt medical attention and effective management strategies. Understanding its causes, implementing preventive measures, and addressing post-treatment scarring can significantly improve outcomes for affected individuals. If you have concerns about your skin condition or treatment options, it is always best to consult with a healthcare professional for personalized advice and care.
