Is amyloid found deep under the skin more dangerous?
When amyloid builds up in the skin, it typically accumulates between the top two layers — the epidermis and dermis. This is characteristic of primary localized cutaneous amyloidosis (PLCA), which affects only the skin and doesn't involve internal organs.

Is amyloid found deep under the skin more dangerous?
When amyloid builds up in the skin, it typically accumulates between the top two layers — the epidermis and dermis. This is characteristic of primary localized cutaneous amyloidosis (PLCA), which affects only the skin and doesn't involve internal organs.
The location of amyloid in the skin itself doesn't necessarily indicate danger. What matters more is whether the amyloidosis is localized (affecting only the skin) or systemic (affecting internal organs like the heart and kidneys).
PLCA generally stays confined to the skin and doesn't spread to other organs. The three types include:
* Lichen amyloidosis — itchy, scaly bumps
* Macular amyloidosis — flat, itchy patches
* Nodular amyloidosis — firm bumps that usually aren't itchy
If you're concerned about amyloid deposits, a skin biopsy can confirm the diagnosis and help determine if it's localized cutaneous amyloidosis or part of a systemic condition. Systemic amyloidosis is more serious because it can affect vital organs, but this would involve symptoms beyond just skin changes.
Talk with your dermatologist about your specific situation to understand what type of amyloidosis you're dealing with.
