The medial portion of the thyroid derives from the median anlage, forming a thyroglossal duct extending from the foramen cecum in the midline of the posterior tongue, descending into the neck. Thyroid tissue may remain anywhere along this path, or fail to descend at all, giving rise to ectopic thyroid tissue or gland. Persistence of the thyroglossal duct may give rise to a visible or palpable cyst [1]. Rarely, a malignancy develops within the cyst. This is most commonly papillary thyroid carcinoma (PTC), and may be associated with a synchronous lesion in the thyroid and with lymph node metastases [2, 3].
