2016
Abstract
This case report describes a young patient with familial dysalbuminemic hyperthyroxinemia in combination with a nonfunctional pituitary adenoma. Familial dysalbuminemic hyperthyroxinemia is a relatively rare autosomal dominant hereditary diseases, which is caused by increased affinity of albumin to thyroid hormones, which causes deviation in the laboratory findings - euthyroid hyperthyroxinemia (normal TSH in combination with elevated serum levels of thyroid hormones).
In fact, it is not a thyroid pathology and patients are clinically euthyroid. This article discussed also the differential diagnosis of hyperthyroxinemia with normal TSH.
