L99: Other disorders of skin and subcutaneous tissue in diseases classified elsewhere
L99.0: Amyloidosis of skin
The body needs proteins for many different tasks. For example, proteins are used as messenger substances or are required for the body’s immune system. Many organs or the muscles also consist of proteins.
The protein deposits cause changes in the skin. Dark patches, small papules or fairly large nodules appear as well as changed areas that are higher than the surrounding skin. The skin changes can be skin-colored to gray or brown and be itchy.
They are mainly found on the upper body and on the fronts of the legs and backs of the arms.
