title: A case of severe and recurrent painless thyroiditis requiring thyroidectomy.
abstract: OBJECTIVE
  To report a case of severe and recurrent painless thyroiditis requiring thyroidectomy.
  
  
  METHODS
  A 47-year-old man who presented with severe thyrotoxicosis was found to have extremely low radioactive iodine uptake, negative TSH receptor antibodies, and normal C-reactive protein; these findings suggested a diagnosis of painless thyroiditis. Due to the severity and recurrence of thyrotoxicosis, surgical resection of the thyroid gland was performed to prevent a thyrotoxic storm. Histological examination revealed typical lymphoid infiltration of the thyroid gland.
  
  
  CONCLUSIONS
  This case illustrates that a patient with painless thyroiditis was successfully treated with surgery.
