Lingual thyroid is a rare developmental disorder, and it is the result of failure of the thyroid gland to descend from the tongue root to its normal site. The ectopic thyroid with a functioning gland is even rarer. In this case, we present a 44-year-old female patient with a complaint of foreign body sensation, progressive dysphagia and dyspnea due to ectopic thyroid tissue. Her complaints were totally resolved after L-thyroxine treatment. Here we report a patient with functioning ectopic thyroid tissue who had had bilateral subtotal thyroidectomy 10 years ago due to multinodular goiter. In conclusion, if progressive dysphagia, dyspnea, and foreign body sensation occurs in a patient who had thyroidectomy and living in an endemic goiter region, lingual thyroid may be underlying disorder.
