Abstract:
Ectopic thyroid is defined as any thyroid tissues not located in the usual site of the thyroid gland, which is anterolateral to 2-4th tracheal rings in the lower neck. These tissues could be present anywhere along the descending tract of a developing thyroid primordium. It is rare for dual ectopic thyroid to have two ectopic foci simultaneously. Twenty-seven cases of dual ectopic thyroid have been reported in the English literature. Physical examinations are usually performed for oral cavity, oropharynx and anterior neck to test for thyroid function, and CT scanning and thyroid scintigraphy are usually performed for the diagnosis of these entities. We report a 19-year-old male with dual ectopic thyroid tissues in lingual and suprahyoid regions but without thyroid tissue in its normal area.
