Amyloidosis refers to the extracellular deposition of a protein called amyloid. This protein deposition can affect multiple organs. The deposition of amyloid may be a by-product of normal aging, or may occur with several other conditions. In this picture, we see how amyloidosis can affect the skin as nodular deposits on the fingers.
