Abstract
A case of lingual ectopic thyroid is reported. The patient was a 63-year-old man with euthyroid symptoms who complained of an abnormal sensation in his throat. An 123I scintigram and CT played an important role in making a diagnosis. After conservative treatment with levothyroxine sodium, the symptoms subsided and the size of the tumor decreased. No unplanned surgical treatment should thus be performed until the functioning thyroid is identified. Although the malignant changes in an ectopic thyroid are considered to be rare, nevertheless a careful long-term follow-up is called for.
