Pediatric Neck Masses
* Congenital masses
* Benign lesions
* Vascular and lymphatic malformations
* Infectious and inflammatory conditions
* Malignant lesions

Embryology and Anatomy
* Branchial System- 6 pairs of pharyngeal arches separated by endodermally lined pouches and ectodermally lined clefts.
* Each arch consists of a nerve, artery, and cartilaginous structures.
* The remaining neck musculature gains contributions from cervical somites.

Branchial system
* First Branchial arch
* Second Branchial Arch
* Third Branchial Arch

Branchial system
* Third Branchial Pouch
* Fourth and Sixth Branchial arches fuse to form the laryngeal cartilages.
* Fourth Arch
* Fourth Pouch- superior parathyroid glands and parafollicular thyroid cells
* Sixth Branchial Arch
* Epipericardial ridge
* Cervical Sinus of His
