The most common form of systemic amyloidosis seen in current clinical practice is AL (primary idiopathic amyloidosis, or that associated with multiple myeloma) resulting from fibril formation by monoclonal antibody light chains in primary amyloidosis and in some cases of multiple myeloma.
The clinical manifestations of amyloidosis are varied and depend entirely on the biochemical nature of the fibril protein and thus the area of the body that is involved.

Although considerable overlap is seen in the organ distribution of various forms of amyloid, primary amyloidosis tends to involve mesodermal tissues, most frequently affecting peripheral nerves, skin, tongue, joints, heart, and liver while secondary amyloidosis mainly affects parenchymatous organs, such as spleen, kidneys, liver, and adrenals.
AL type of amyloidosis is also associated with some other rare monoclonal gammopathies (plasma cell/B immunocyte dyscrasias), such as solitary myeloma (of bone or soft tissue), Waldenstrom's macroglobulinemia, or heavy chain disease in which there are also sometimes an increased production of free light chains that become deposited as amyloid.
Noteworthy, the majority of patients who develop AL type of amyloidosis apparently do so in the absence of clinically overt myeloma or other predisposing disease, and such cases are commonly referred to as primary or idiopathic amyloidosis.
