Primary amyloidosis

Amyloidosis - primary; Immunoglobulin light chain amyloidosis; Primary systemic amyloidosis; Primary localized amyloidosis

Primary amyloidosis is a rare disorder in which abnormal proteins build up in tissues and organs. Clumps of the abnormal proteins are called amyloid deposits.

Amyloidosis of 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 of 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.
