Tiroides ectópico: causa rara de tumoración cervical en el niño.

Title: Ectopic thyroid: a rare cause of a neck mass in a child Ectopic thyroid is the presence of functional thyroid tissue at a site other than its normal pretracheal position. Its prevalence in the general population is very low, and it rarely produces a mass. Here, we present the case of an 8-year-old girl with a neck mass that was diagnosed as ectopic thyroid tissue. In children with neck masses, the location of the thyroid gland in its normal position by routine ultrasound scan is a reliable and noninvasive method of ruling out ectopic thyroid and avoiding its inadvertent excision. In spite of its rarity, this diagnosis should be considered in the evaluation of any child with a neck mass.
