-Etiology: The cause of branchial cyst is incomplete involution of branchial cleft structures.

-Genes involved: Unknown.

 -Pathogenesis: The internal opening of the branchial sinuses arising from incomplete obliteration in embryogenesis.

-Morphology: They may be on the anterior neck and upper chest bumps. 

 -Histology: The histology associated with branchial cysts shows cysts lined by stratified squamous epithelium that may contain keratinous debris.

How do Branchial Cysts Present?

Patients with branchial cyst typically are equally common in males and females and usually present in childhood or early adulthood. The symptoms, features, and clinical findings associated with branchial cyst include neck lumps.

How are Branchial Cysts Diagnosed?

Branchial cysts are diagnosed by ultrasound and biopsy.

How are Branchial Cysts Treated?
