amyloidosis occurring in association with another chronic inflammatory disease; organs chiefly involved are the liver, spleen, and kidneys, and the adrenal glands less frequently.

amyloidosis

the deposition in various tissues of amyloid. This protein is almost insoluble and once it infiltrates the tissues they become waxy and nonfunctioning. Systemic amyloidosis may be immunocytic or reactive (see below).

cutaneous amyloidosis
multiple cutaneous, hard, painless, chronic plaques occur over the head, neck and shoulders of horses. There may be involvement of the nasal mucosa and resulting dyspnea.
familial renal amyloidosis of Shar pei dogs
manifested by episodic fever and swelling of one or both hocks which may resolve spontaneously, but is recurring. The condition is resistant to treatment and eventually there is renal and/or hepatic failure.
immunocytic amyloidosis, immunogenic amyloidosis, primary amyloidosis
amyloid produced from light chains of immunoglobulins as in plasma-cell dyscrasias. See also al protein.
reactive amyloidosis
is derived from excess serum protein SAA produced as a result of chronic antigenic stimulation. The kidney is most often affected and the amyloid is most often deposited in glomeruli but medullary deposits are seen in cats and cattle. Idiopathic amyloidosis is common in the dog and less common in cats. It is associated with chronic suppurative disease processes in cattle, antiserum production in horses, and it occurs rarely in pigs. Called also secondary alopecia.
renal amyloidosis
characterized by severe proteinuria and uremia. There is chronic diarrhea, polydipsia and anasarca. Seen particularly in dogs and cats.
secondary amyloidosis
