Skin Issues: What to Do About Back Skin Loss - Dermatology

Skin of the back


Hello Doctor,
Recently, I suddenly noticed a spot on my back where the skin feels as if it has been burned, and the epidermis seems to be missing.
To describe it more clearly, it resembles the scar I had on my left arm after receiving a vaccination when I was a child.
I'm not sure why this is happening; could it be a bacterial infection since the epidermis is gone? It also seems to be getting larger, which makes me a bit worried.
I took some photos, but I'm not sure how to attach them to this question.
If you would like to see the photos, I can send them to you in a separate electronic file.
I appreciate your help in addressing my concerns.
Thank you!

Dear Student Li,
Based on your description, it is currently unclear what your specific medical condition is.
However, I recommend that when you notice symptoms such as "the epidermis has disappeared," you should promptly visit a public hospital under the Department of Health in your city or county and consult with a dermatologist.
I believe the physicians there will be happy to provide you with the necessary treatment.
Thank you for using "Taiwan e-Hospital" to ask your question; "Taiwan e-Hospital" cares about your health.

Dear Patient,
Thank you for reaching out with your concerns about the sudden skin loss on your back. Based on your description, it sounds like you may be experiencing a condition that could be related to several factors, including skin infections, inflammatory skin diseases, or even an allergic reaction. The sensation of your skin feeling like it has been burned, along with the loss of the epidermis, is indeed concerning and warrants further investigation.

Firstly, it is essential to understand that the skin serves as a protective barrier for the body. When the skin's outer layer (the epidermis) is compromised, it can lead to various symptoms, including redness, irritation, and even pain. The appearance you described, similar to a scar from a vaccination, suggests that there may be a localized inflammatory response or damage to the skin.

One possible cause of your symptoms could be a bacterial infection, such as impetigo, which can cause blistering and peeling of the skin. Another possibility is a condition known as eczema or dermatitis, which can lead to skin peeling and irritation, especially in response to environmental changes or allergens. Given that you recently moved to a different climate, your skin may be reacting to the colder and drier conditions, which can exacerbate existing skin issues or create new ones.

It's also worth considering the possibility of an allergic reaction to a product you may have used, such as soaps, lotions, or even laundry detergents. Allergic contact dermatitis can cause localized skin reactions that may resemble what you are experiencing.

In terms of treatment, it is crucial to avoid any further irritation to the affected area. Here are some steps you can take:
1. Keep the Area Clean and Dry: Gently cleanse the affected area with mild soap and lukewarm water. Avoid scrubbing, as this can worsen irritation.

2. Moisturize: Apply a fragrance-free moisturizer to the area to help restore the skin barrier. Look for products that contain ceramides or hyaluronic acid, which can help retain moisture.

3. Avoid Irritants: Steer clear of any products that may contain alcohol, fragrances, or harsh chemicals that could further irritate your skin.

4. Topical Treatments: If the area is red, inflamed, or itchy, over-the-counter hydrocortisone cream may help reduce inflammation. However, if the condition worsens or does not improve, it is essential to consult a healthcare professional.

5. Seek Medical Attention: Given that the area seems to be increasing in size and you are experiencing discomfort, I strongly recommend that you see a dermatologist or healthcare provider as soon as possible. They may perform a physical examination and possibly a skin biopsy to determine the exact cause of your symptoms.

6. Document Your Symptoms: Since you mentioned having photos, it would be beneficial to bring these along to your appointment. Visual documentation can help the doctor assess the progression of your condition.

In conclusion, while it is difficult to provide a definitive diagnosis without a physical examination, your symptoms suggest that you may be dealing with a skin condition that requires professional evaluation. Early intervention can help prevent further complications and promote healing. Please do not hesitate to seek medical advice, as timely treatment is crucial for skin health.

Take care, and I wish you a speedy recovery.
