Acquired hypothyroidism and ectopic lingual thyroid tissue

The presence of ectopic thyroid tissue is a rare entity. The non-gland migration occurs in the early stages of embryogenesis to your normal cervical location. Thus, the ectopic tissue lodges in general in the path of the thyroglossal duct, in the middle line of the neck. The most common location is in the lingual zone, being called a lingual thyroid. This, in most cases will be asymptomatic. However, it is able to manifest itself with symptoms of dysphagia, dysphonia, obstruction of upper airways or hemorrhage at any moment between childhood and adulthood. We present a rare case of lingual thyroid in a man of 43 years, when hormonal tests were normal, however scintigraphy confirmed the diagnosis associated with surgical pathology, which revealed nodular goiter hyperplastic ectopic in association with lymphocytic thyroiditis type Hashimoto's thyroiditis. This article is a review of this disease, targeting mainly the conduct, still very controversial in world literature.
