A thyroglossal cyst or thyroglossal duct cyst is a fibrous cyst that forms from a persistent thyroglossal duct. Thyroglossal cysts can be defined as an irregular neck mass or a lump which develops from cells and tissues left over after the formation of the thyroid gland during developmental stages.
A persistent thyroglossal duct is a usually benign medical condition in which the thyroglossal duct, a structure usually only found during embryonic development, fails to atrophy. The duct persists as a midline structure forming an open connection between the back of the tongue and the thyroid gland. This opening can lead to fluid accumulation ...
Thyroid disease is a medical condition that affects the structure and/or function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
A thyroidectomy is an operation that involves the surgical removal of all or part of the thyroid gland. In general surgery, endocrine or head and neck surgeons often perform a thyroidectomy when a patient has thyroid cancer or some other condition of the thyroid gland (such as hyperthyroidism) or goiter. Other indications for surgery include ...
Papillary thyroid cancer (magnified at right) arising within ectopic thyroid tissue of a thyroglossal cyst is a rare occurrence (less than 1% of such cysts). [38] According to Surveillance, Epidemiology, and End Results (SEER), the incidence of papillary cancer has increased from 4.8 to 14.9 per 100,000 from 1975 to 2012. Females are more ...
[6] [9] Surgical removal of the mass is the definitive treatment for ectopic thymus tissue that is causing symptoms. [4] It has been reported that the ectopic thymus tissue can transform into cancerous tissue. [4] However, due to most diagnosed ectopic thymus tissue being resected due to this concern, the natural progression is not well explored.
The thyroglossal duct is an embryological anatomical structure forming an open connection between the initial area of development of the thyroid gland and its final position. It is located exactly mid-line, between the anterior 2/3 and posterior 1/3 of the tongue .
A baby with a prenatally diagnosed cystic hygroma should be delivered in a major medical center equipped to deal with neonatal complications, such as a neonatal intensive care unit. An obstetrician usually decides the method of delivery. If the cystic hygroma is large, a cesarean section may be performed. After birth, infants with a persistent ...
