Amyloidosis on the Fingers

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.

Amyloidosis on the Face

Amyloidosis refers to deposits of a protein (called amyloid) in the tissues. This condition can affect multiple organs. The deposition of amyloid may be a by-product of normal aging. In this picture, we see how amyloidosis can cause a patchy, bruised appearance to the skin. Bruises of the skin around the eyes are referred to as the characteristic "pinched purpura".

Antibodies

Antigens are large molecules (usually proteins) on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, drugs, and foreign particles. The immune system recognizes antigens and produces antibodies that destroy substances containing antigens.
