The majority of cystic squamous cell carcinomas (SCCs) of the neck have been shown to be metastatic tumors from tonsillar SCCs associated with high-risk human papillomavirus (HR HPV).

Second branchial cleft cyst is the most common type, which is found in about 95% of cases (Panchbhai and Choudhary 2012). Branchial cysts are common in the lateral aspect of the neck. They usually appear as a fluc...
