Bocio multinodular ectópico submandibular: a propósito de un caso y revisión de la literatura

Ectopic Thyroid with Multinodular Goiter-Case Report

“…The thyroid gland is normally located in the anterior region of the neck, between the second and fifth tracheal rings. It develops between the third and fourth week of gestational age, being the first endocrine gland to develop [1,2,5]. Ectopy of the thyroid gland is an infrequent clinical condition [6].…”

“…The symptoms are related to the size and location of the gland, as well as symptoms of dysfunction [5]. Those located in the lateral region of the neck can present as cervical tumors, which must be differentiated from salivary gland tumors, lymphadenopathy, and other subcutaneous inflammations [2,5]. There is no consensus in the literature on the assessment and management of this condition.…”

“…There is no consensus in the literature on the assessment and management of this condition. Imaging studies (neck ultrasound, computed tomography and magnetic resonance) are the initial studies that guide the diagnosis [2,5,7].…”

“…Likewise, PAAF is a highly sensitive procedure (95-97%) for the diagnosis of colloid tissue. Finally, the analytical study of thyroid hormones is essential to assess the presence of functional alterations of the thyroid gland [2,3,5].…”

“…The ectopic thyroid gland is defined as that which isn't in its orthotopic position in the anterior region of the neck, at the pre tracheal level between the second and fifth rings [1,2]. The thyroid gland originates from a diverticulum located in the midline between the first and second branchial arches.…”
