Abstract
La tiroides lingual, tejido tiroideo ectópico benigno, representa una entidad clínica rara; frecuentemente es asintomática, en ocasiones su crecimiento provoca sensación de cuerpo extraño, disfagia, disfonía o disnea. Se describe el caso de una niña de nueve años de edad, atendida por presentar sensación de cuerpo extraño en la faringe, dos meses antes de acudir a la consulta. Al examen físico se observó una masa rojiza de aproximadamente 2 x 2.5 cm en la base de la lengua; no se palpó tiroides en la posición pretraqueal; la centellografía con Tc-99 evidenció la ausencia de captación tiroidea pretraqueal normal con zona de captación en la base de la lengua asociado con un hipotiroidismo subclínicos.
Lingual thyroid, benign ectopic thyroid tissue, represents a rare clinical entity, is often asymptomatic, their growth often causes foreign body sensation, dysphagia, dysphonia, or dyspnea. We describe a 9-years old girl attended with a foreign body sensation in the pharynx, two months before going to consultation. By the physical examination, in the base of the tongue, a reddish mass of approximately 2 x 2.5cm was observed; pretraqueal position in the thyroid was not palpated, the scintigraphy with Tc-99 demonstrated the absence of normal pretraqueal thyroid uptake, with uptake area at the base of the tongue, associated with subclinical hypothyroidism.
