Article information

El tiroides ectópico es una alteración congénita infrecuente, consecuencia de la migración defectuosa del tiroides desde el agujero ciego (foramen caecum) hasta su posición final pretraqueal. La localización más frecuente del tejido tiroideo ectópico es lingual y sublingual. En la mayoría de los casos el único tejido tiroideo que queda suele ser ectópico. Puede ser asintomático o con clínica variable. Presentamos 2 casos de tiroides ectópicos (sublingual y precricoideo). Los 2 casos asociaban hipofunción tiroidea y síntomas locales. Revisamos la clínica y el manejo diagnóstico y terapéutico.

Ectopic thyroid tissue is a rare abnormality caused by the failure of the thyroid gland to migrate from the foramen cecum to its final pretracheal position. The most frequent sites of ectopic thyroid tissue are lingual and sublingual. In most patients, the ectopic tissue is the only source of functioning thyroid. Ectopic thyroid may be asymptomatic or may produce variable symptoms. We describe 2 cases of ectopic thyroid (sublingual and precricoidal). Both patients had hypothyroidism and local symptoms. We review the clinical features, diagnosis and treatment of this entity.

Key words:
Ectopic thyroid
Hypothyroidism
Subblingual thyroid
