Amyloid deposition

Dear Doctor,
I would like to ask about amyloid deposition.
What is it and how does it occur? I have been troubled for many years by streaks of dark and light pigmentation all over my limbs, especially on the outer sides of my hands and feet, which are particularly unsightly.
This has made me hesitant to wear short sleeves or skirts.
Previously, I used a combination of Dermovat ointment and Salic ointment, but there has been no improvement at all.
What are the uses of these two ointments? Besides applying ointments, are there other treatment options available? Thank you for your response!

It may be associated with certain chronic inflammatory diseases.
In addition to topical ointments, some have attempted to treat it with cauterization or dermabrasion, but these methods are not effective for every patient.
Sincerely, Dr.

More Info

Dear Patient,
Thank you for your inquiry regarding amyloid deposits and their potential impact on your skin condition. Amyloid deposits are abnormal protein aggregates that can accumulate in various tissues and organs, including the skin. This condition is often associated with systemic diseases, such as multiple myeloma, chronic inflammatory diseases, and certain genetic disorders. The presence of amyloid in the skin can lead to various dermatological manifestations, including changes in pigmentation, thickening of the skin, and the formation of plaques.

The appearance of "striped black and white pigmentation" on your limbs, particularly on the outer sides of your hands and feet, could be indicative of a few different conditions. While it is essential to have a thorough evaluation by a dermatologist to determine the exact cause, it is possible that what you are experiencing may not be directly related to amyloid deposits but could be due to other skin conditions such as lichen planus, vitiligo, or even post-inflammatory hyperpigmentation resulting from previous skin injuries or conditions.

Regarding the topical treatments you mentioned—Dermovat ointment (which contains clobetasol propionate, a potent topical corticosteroid) and salicylic ointment (which typically contains salicylic acid, known for its keratolytic properties)—these medications serve different purposes. Dermovat is used to reduce inflammation and alleviate symptoms associated with various skin conditions, while salicylic acid helps to exfoliate the skin and can be beneficial in treating conditions like psoriasis or acne. However, if you have been using these treatments without improvement, it may indicate that your condition requires a different therapeutic approach.

In terms of treatment options beyond topical medications, there are several avenues you might explore:
1. Phototherapy: This involves exposing the skin to ultraviolet light under medical supervision. It can be effective for various skin conditions, including psoriasis and eczema.

2. Systemic Treatments: If your condition is more severe or widespread, systemic medications (oral or injectable) may be necessary. These can include immunosuppressants or biologics, depending on the underlying cause.

3. Laser Therapy: Certain types of laser treatments can help improve skin pigmentation issues and may also reduce the appearance of amyloid deposits if they are present.

4. Moisturizers and Skin Care: Regular use of emollients and moisturizers can help maintain skin hydration and barrier function, which is crucial for overall skin health.

5. Lifestyle Modifications: Maintaining a healthy diet, staying hydrated, and avoiding known irritants can also play a role in managing skin conditions.

6. Consultation with a Specialist: Given the complexity of your symptoms, it may be beneficial to consult with a dermatologist who specializes in pigmentary disorders or systemic diseases that affect the skin.

In conclusion, while amyloid deposits can lead to skin changes, it is essential to have a comprehensive evaluation to determine the exact nature of your skin condition. The treatments you have used may not be effective for your specific issue, and exploring alternative therapies or a combination of treatments may yield better results. Please consider scheduling an appointment with a dermatologist for a thorough assessment and tailored treatment plan.

Best wishes for your skin health, and I hope you find relief soon.

Sincerely,
