de Quervain's thyroiditis, can also be known as subacute granulomatous thyroiditis or Giant Cell Thyroiditis. Males and females of all ages may be affected. It is a member of the group of thyroiditis conditions known as resolving thyroiditis.
It is sometimes called subacute thyroiditis, but there are other forms of subacute thyroiditis, subacute lymphocytic thyroiditis, post partum thyroiditis, and autoimmune thyroiditis all of which, in contrast to de Quervain's, are typically painless or "silent".
It is also sometimes called "painful subacute thyroiditis". This is in contrast to subacute lymphocytic thyroiditis, which is also sometimes called "painless thyroiditis".
Some cases may be viral in origin, perhaps preceded by an upper respiratory tract infection. Viral causes include Coxsackie virus, mumps and adenoviruses. Some cases develop postpartum .
