Ectopic thymic tissue in the thyroid gland.

abstract：:Crohn's disease is one of the causes of secondary amyloidosis, which can lead to amyloid infiltration of the thyroid gland. It is essential to follow strict controls to prevent the appearance of a large amyloid goiter. Two patients with amyloid goiter secondary to Crohn's disease, with a large adipose tissue component...
