Amyloidosis - secondary systemic
Secondary systemic amyloidosis is a disorder in which abnormal proteins build up in tissues and organs. Clumps of the abnormal proteins are called amyloids.
Secondary means it occurs because of another disease or situation. For example, this condition occurs along with chronic infection or chronic inflammatory disease.
Systemic means body-wide. For example, a systemic disease affects the entire body.
