Secondary systemic amyloidosis
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 that the disease affects the entire body.
