Congenital Skin Conditions: Insights on Persistent Symptoms - Dermatology

A skin condition present at birth?


Hello Doctor, I have had this symptom since birth that resembles scleroderma.
During seasonal changes, it becomes dry and itchy, and I feel the urge to scratch it.
Sometimes, if I scratch too hard, it bleeds.
When it's dry, the color appears white, and it extends from my left leg up to my buttocks.
I underwent cryotherapy when I was younger, but it still reappears after treatment.
My parents mentioned it might be a condition called "melanocytic nevus," but I couldn't find any similar cases online after searching for a long time.
I also visited a dermatology clinic previously, but they couldn't provide an answer, so I am consulting you here.
Thank you!

Without actually seeing the lesion, it is impossible to determine the issue.
If it is very concerning, please seek medical attention as soon as possible.
Only after an examination can the problem be identified and addressed.

Understanding congenital skin conditions can be quite complex, especially when symptoms persist from birth. Based on your description, it seems you are experiencing a condition that resembles scleroderma, characterized by hardening of the skin, dryness, itching, and potential bleeding from scratching. This can be particularly distressing, especially when it affects your mobility and comfort.

Firstly, it’s important to clarify that "maternal nevus" or "mother's mark" is not a recognized medical term for a specific skin condition. It might refer to various congenital skin lesions, such as nevi (moles) or other pigmented lesions that can appear at birth. However, the symptoms you describe—thickened, itchy skin that can bleed when scratched—suggest a different underlying issue.

The symptoms you are experiencing could be indicative of a condition known as "ichthyosis," which is a group of skin disorders characterized by dry, scaly skin. Ichthyosis can be congenital (present at birth) and varies in severity. In some cases, it can be associated with other systemic conditions, but in many instances, it is isolated to the skin. The fact that your symptoms worsen with seasonal changes suggests a possible link to environmental factors, such as humidity and temperature, which can exacerbate dry skin conditions.

Another possibility is that you may be dealing with a form of eczema, particularly if the skin becomes inflamed and itchy. Eczema can manifest in various forms, including atopic dermatitis, which is often associated with a personal or family history of allergies or asthma. The chronic nature of your symptoms, along with the tendency to scratch, could lead to a cycle of irritation and secondary infections, which might explain the bleeding.

In terms of management, it is crucial to maintain a regular skincare routine that focuses on hydration. Using emollients or moisturizers frequently can help alleviate dryness and reduce itching. Look for products that are fragrance-free and designed for sensitive skin. Additionally, topical corticosteroids may be prescribed by a dermatologist to help reduce inflammation during flare-ups.

If you have already undergone treatments like cryotherapy without lasting results, it may be beneficial to seek a second opinion from a dermatologist who specializes in congenital skin disorders. They can conduct a thorough examination and possibly perform a biopsy if necessary to determine the exact nature of your condition. Genetic testing may also be an option if a hereditary skin disorder is suspected.

Lastly, it’s essential to avoid scratching as much as possible, as this can lead to further skin damage and complications. Keeping your nails trimmed and using protective clothing can help minimize the risk of injury to the skin.

In conclusion, while your symptoms are persistent and can be distressing, there are management strategies available. A comprehensive evaluation by a dermatologist will provide you with a clearer understanding of your condition and the most effective treatment options. Remember, skin conditions can often be managed effectively with the right approach, so do not hesitate to seek further medical advice.
