Secondary systemic amyloidosis is a disorder in which abnormal proteins build up in tissues and organs. Clumps of the abnormal proteins are called amyloid deposits.
Secondary means it occurs because of another disease or situation. For example, this condition usually occurs as a result of chronic infection or chronic inflammatory disease. Primary amyloidosis means there is no disease that is causing the condition.
Systemic means body-wide. For example, a systemic disease affects the entire body.

How well a person does depends on which organs are affected and whether the disease that is causing it can be controlled. If the disease involves the heart and kidneys, it may lead to organ failure and death.
