The most frequent place of ectopic thyroid tissue is the base of tongue, whereas lateral thyroid gland is a very rare finding. The present case describes a case of thyroid dysgenesis, caused by a submandibular ectopic thyroid gland. Thyroid scintigraphy was crucial for the diagnosis: in fact, the patient was asymptomatic, and the diagnosis was performed only on the basis of subclinical hypothyroidism.
