Fibrosis quística, bocio e hipertiroidismo

Thyroid gland enlargement due to amyloid infiltration, known as amyloid goitre, is a rare clinic entity. In most reported cases, patients' thyroid function is normal; less frequent is the presentation with thyroid hypofunction, and exceedingly rare is its association with thyroid hyperfunction. We hereby report a case of amyloid goitre and primary hyperthyroidism, due to systemic amyloidosis, in a patient with cystic fibrosis, without compressive symptoms. Then, we provide a brief review of this entity and its therapeutic management.
