[Amyloid goiter: first sign of systemic amyloidosis]

Although amyloid infiltration of the thyroid gland is an uncommon but well-known phenomenon, the appearance of a goiter secondary to amyloid deposits is rare. The goiter enlarges rapidly and progressively, often becoming compressive like thyroid cancer. The diagnosis is rarely suggested clinically even in the presence of known amyloidosis. We describe the case of a 45-year-old patient who presented an amyloid goiter as the first manifestation of systemic amyloidosis, probably secondary to bronchiectasis.
