Abstract:
Thyroglossal duct cysts (TDC) are the most common congenital neck masses. Although they are anatomically closely related to the larynx, intra-laryngeal extension is very rare. We present a case, review the literature and discuss the challenges of intra-laryngeal TDC. A 55-year-old man presented with a neck mass associated with dysphagia. Computer Tomography neck scan showed a midline cyst extending to the pre-epiglottic space with partial obliteration of the right pyriform sinus and narrowing of the larynx. The cyst was excised en-bloc via Sistrunk procedure. Intra-laryngeal TDC are surgically challenging due to risk of perforation into the aerodigestive tract.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
