Amyloid tumor of thyroid, amyloid goiter: A case report with a stress on importance of preoperative diagnosis

Although involvement of the thyroid gland by amyloid is a relatively common phenomenon, clinically significant enlargement of the thyroid owing to amyloid deposition is an extremely rare occurrence. Deposition of amyloid is commonly found in the kidneys, spleen, liver, lymph nodes, nerves, skin, heart, gastrointestinal tract, lungs, and blood vessels. We present a rare case of amyloid deposition in thyroid, leading to amyloid goiter which is still rarer.
