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 ...
The first resection of thyroglossal duct cyst showed histopathology evidence of Hurthle cell type thyroid cancer. However, the second resection showed signs of chronic inflammation, with no malignant cells. a, b Enhanced axial and sagittal neck CT scans demonstrate a unilocular cystic lesion arising from the tongue base and extending through ...
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 .
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 ...
If resolution of the cystic hygroma does not occur before birth, a pediatric surgeon should be consulted. [10] Cystic hygromas that develop in the third trimester, after 30 weeks' gestation, or in the postnatal period are usually not associated with chromosome abnormalities. A chance exists of recurrence after surgical removal of the cystic ...
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.
Squamous epithelial cells are not found in a normal thyroid, so the origin of SCT is not clear. However, it might be derived from embryonic remnants such as thyroglossal ducts or branchial clefts. Often, SCT is diagnosed in one of the thyroid lobes but not in the pyramidal lobe.
