AA amyloidosis is a form of amyloidosis associated with serum amyloid A protein (SAA), an acute-phase protein.

AA amyloidosis shows a predilection for the spleen, liver, kidneys, adrenals, and lymph nodes. The liver, spleen, and kidneys are often enlarged, firm, and rubbery. Involvement of the heart and peripheral or autonomic nerves is rare.

In AA amyloidosis (formerly known as secondary amyloidosis), the main fibril protein is serum amyloid A protein (abbreviated A), giving rise to the abbreviation AA for the disease.
