ABSTRACT

Amyloid goiter is defined as thyroid gland enlargement due to deposition of amyloid material. Although microscopic thyroid involvement in systemic amyloidosis is 50%-80%, isolated thyroid gland amyloidosis is very rare. We present a case who underwent thyroidectomy because of pressure symptoms and was histopathologically diagnosed as diffuse amyloid deposition without findings of systemic amyloidosis.
