Clinical data: A 39-year-old man came to a routine follow-up. He was operated on a recurrent hyperthyroidism of autoimmune origin 7 years ago. Histopathology disclosed diffuse goiter for more than 20 years. After surgery, 75 and 100 micrograms a day of hormone replacement were needed for years. Then, three years before the current study, hormone results suggested an overdose. He was euthyroid for a year and a half after leaving drug replacement.
Palpation: no abnormality.
