The term subacute thyroiditis now describes a well-defined clinical entity, characterised by a generally self-limiting, usually painful pseudogranulomatous inflamation of the thyroid, probably of viral origin. It is the most frequent cause of painful thyroid and the second most frequent thyroiditis. In spite of that it is considered to be a rare disesase. The diagnostics and treatment of subacute thyroiditis makes problems not only to general practitioners, but also to endocrinologists. A very simple way how to increase the retention, to initiate quick diagnostics and shorten painful phase of the disease is to palpate the neck in all patients suffering from „sore throat“.
