“…Thyroid heterotopias can sit along the embryonic migration path of the thyroid [ 2 ]. The most frequently encountered site is the base of the tongue (90%), and sub-hyoid localizations are the rarest [ 2 ]. A few cases of extra-cervical heterotopias have been reported in the literature [ 1 , 2 , 5 ].…”

“…The most frequently encountered site is the base of the tongue (90%), and sub-hyoid localizations are the rarest [ 2 ]. A few cases of extra-cervical heterotopias have been reported in the literature [ 1 , 2 , 5 ]. The hormonal balance in heterotopias remains normal due to a normally located and functional gland, unlike ectopias which are accompanied by varying degrees of hypothyroidism [ 7 ].…”

“…The observed patient had a normal assessment, explained by the coexistence of a functional thyroid in a normal position. Mazouz et al .in 2016 reported a case of mediastinal heterotopia accompanied by thyrotoxicosis [ 2 ].…”

“…Thyroid heterotopia is an abnormal localization of normal thyroid tissue coexisting with a normal organ on a normal localization. It is a congenital anomaly due to a defect in maturation and migration of thyroid tissues [ 1 , 2 ]. It is a rare condition whose frequency is not well known in the general literature.…”

“…Ectopic localizations of the thyroid gland occur along the thyroglossal tract with a predominance in 90% of cases on the base of the tongue [ 3 , 4 ]. However, a few cases of extra-cervical, mediastinal or pre-sternal localizations have been reported in the literature [ 1 , 2 , 5 ].…”

Thyroid heterotopia is an abnormal localization of normal thyroid tissue coexisting with a normal organ on a normal localization. It is a rare condition with a frequency that is not well known in the literature. We report a case of thyroid heterotopia in a 30 month-old girl referred for a painless lower antero-cervical nodule that has been developing for one year with past history no contributory. The clinical examination found a subcutaneous formation mobile in relation to the different deep and superficial planes with bilateral angulomandibular micro-lymphadenopathy. Ultrasounds of the soft parts of the neck showed hypoechogenic tissue reminiscent of thyroid tissue, the thyroid was in place. The thyroid hormone profile was normal. In the absence of a functional scintigraphy device, the diagnosis was confirmed with a pathology exam after surgery. We discuss the diagnostic relevance of thyroid heterotopia in front of any anterior nodular formation of the neck.
