Dual ectopic thyroid - A case report of a very rare disease

Ectopic thyroid is a developmental defect of thyroid gland that leads to presence of thyroid tissue at sites other than its normal pretracheal location. It is frequently found along the course of the thyroglossal duct but can also be found at remote distant sites. Lingual thyroid is the most common presentation of ectopic thyroid. It is very rare to have two ectopic foci of thyroid tissue simultaneously and only 19 cases of dual ectopia have been reported in world literature. In 70 of cases of ectopic thyroid the normal thyroid gland is absent. We report a case of 12 year old girl presented with dual ectopic thyroid.
