[en] Ectopic thyroid is a thyroid dysgenesiswith an average prevalence of 1 in 200,000 people, female predominance,and lingual thyroid being the most common presentation of the ectopic tissue. This happens as a consequence of an error in the process of migration of the thyroid gland,which can be positioned at any location across the embryological pathway. We present three cases of ectopic thyroid: an asymptomatic pediatric patient with high cervical tumor corresponding to its unique thyroid gland, an adult female with dual ectopic thyroid glandswith dysphagia as the only symptom, and a male patient with a normal thyroid gland and ectopic thyroid tissue in the middle cervical region
