Painless giant cell thyroiditis.

Lugol's solution-induced painless thyroiditis

Lugol's solution is usually employed for a limited period for thyroidectomy preparation in patients with Graves' disease and for the control of severe thyrotoxicosis and thyroid storm. We describe a rare case of Lugol's solution-induced painless thyroiditis. In November 2014, a 59-year-old woman was prescribed Lugol's solution four drops per day for the alleviation of menopausal symptoms. She w...

Painless thyroiditis complicated by acromegaly.

The serum thyroid stimulating hormone (TSH) level is decreased in acromegalic patients. Although this phenomenon is thought to be caused by the enhanced secretion of somatostatin which suppresses TSH production, it has not yet been proven. We describe a 60-year-old woman with acromegaly who showed a low concentration of TSH. We diagnosed her as painless thyroiditis based on an increased level o...

Primary biliary cirrhosis associated with painless thyroiditis.

A case of anti-mitochondrial antibody (AMA)-negative primary biliary cirrhosis (PBC) associated with painless thyroiditis is reported in a 47-year-old woman who diagnosed as PBC based on her elevated serum gamma-glutamyl transpeptidase and immunoglobulin M levels, as well as histological findings of destroyed bile ducts surrounded by mononuclear infiltrates in the biopsied liver. She was negati...

Simultaneous onset of giant cell arteritis and subacute thyroiditis.

Acute exacerbation of chronic thyroiditis with painless thyroid.

Destruction-induced thyrotoxicosis includes various painful diseases such as subacute granulomatous thyroiditis, acute exacerbation of chronic thyroiditis and acute suppurative thyroiditis. In contrast, the clinically painless form of destruction-induced thyrotoxicosis is almost exclusively restricted to painless or silent thyroiditis. We report what we believe to be a case of acute exacerbatio...
