2019年5月5日 · Most thyroglossal duct cysts are located close to the hyoid bone. The thyroid gland derives from endoderm originating from the junction of the anterior two-thirds and posterior one-third of the tongue (foramen cecum). A thyroglossal duct cyst is due to incomplete obliteration of the thyroglossal duct. It is rarely seen off the midline.

2023年10月1日 · There are many possible causes of congenital neck masses, with the most common ones being thyroglossal duct cysts, branchial cleft anomalies, and vascular malformations.

Thyroglossal duct cysts and branchial cleft anomalies are important in the differential diagnosis of cervical lesions. Both lesions are common and are seen more commonly in the child than in the adult.

Second branchial cleft cyst: Contrast enhanced CT scan reveals a cystic lesion (arrows) in the right neck lateral to the carotid sheath, behind the submandibular gland and along the anterior border of the sternocleidomastoid muscle

Histopathological diagnosis of TGD requires optimally evidence of respiratory / squamous epithelial lining and thyroid follicles, which sometimes can be difficult to find due to inflammation and fibrosis; in these situations, a diagnosis of developmental cyst with comment (favor TGD cyst or branchial cleft cyst, etc.) may be an option

2015年8月1日 · First branchial cleft: preauricular area (type I cyst) or below the angle of mandible (type II), may be connected to external auditory canal; cysts are rarely malignant (Diagn Cytopathol 2008;36:876); 5% - 8%

2023年6月30日 · Branchial cleft cysts, also known as branchial cleft anomalies, are congenital anomalies arising from the first through fourth pharyngeal pouches. These anomalies can exist as true fistulae, cysts, or sinus tracts, depending on the degree of …

Neck masses in children usually fall into one of three categories: developmental, inflammatory/reactive, or neoplastic. Common congenital developmental masses in the neck include thyroglossal...

Branchial cysts originate from the branchial apparatus, whereas thyroglossal duct cysts stem from remnants of the thyroglossal duct. Their anatomical locations also differ, with branchial cysts typically found laterally and thyroglossal duct cysts located near the midline.

Branchial cleft cysts (BCCs) are also named lateral cervical cysts and widely acknowledged as being derived from embryonic remnants. Lymphoepithelial cysts (LECs) generally show microscopic features that are identical to those of BCCs, and rarely occur at …
