[A case of a midline cervical cyst]. / Su di un caso di cisti mediana del collo.

ABSTRACT

Midline cervical cysts are one of the most common embryological anomalies of the neck. They are due to the failure of a complete obliteration of the thyroglossal duct. This endodermal structure arises from the floor of the mouth and proceeds caudally in the midline of the neck until it reaches its final position around the trachea. Finally, the inferior portion of the thyroglossal duct develops into the median lobe of the thyroid gland whereas its cranial portion disappears. In the present paper, the clinical feature and the surgical treatment of a case is described.
