Branchial cleft cysts are congenital epithelial cysts, which arise on the lateral part of the neck due to failure of obliteration of the second branchial cleft in embryonic development.


Contents

Pathology

The cyst wall will be composed of either squamous or columnar cells with lymphoid infiltrate, often with prominent germinal centers. The cyst may contain granular and keratinaceous cellular debris. Cholesterol crystals may be found in the fluid extracted from a branchial cyst.

Pathophysiology

Branchial cleft cysts are remnants of embryonic development and result from a failure of obliteration of the branchial cleft, which in fish develop into gills.[1][2]

Types

Symptoms

Most branchial cleft cysts are asymptomatic, but they may become infected.

Treatment

Bilateral branchial cleft sinuses during surgery.

Conservative (i.e. no treatment), or surgical excision. As complete surgical excision may be difficult (due to the close proximity of the internal jugular vein and carotid vessels that lie deep to the swelling), they can recur.[3]
