Amyloid goiter in a case of systemic amyloidosis secondary to ankylosing spondylitis

Infiltrative diseases of the thyroid include systemic sclerosis, hemochroma tosis, sarcoidosis, chondrocalcinosis and amyloidosis. Only rarely does thy roid amyloidosis result in clinically palpable goiter. Classically, amyloid osis is associated with tuberculosis, rheumatoid arthritis, multiple myelom a or inflammatory bowel disease. Only rarely does clinical amyloidosis deve lop in the setting of ankylosing spondylitis. We describe a case of amyloid goiter in a patient with ankylosing spondylitis-associated amyloidosis.
