Branchial cleft cyst and branchial cleft cyst carcinoma, or cystic lymph node and cystic nodal metastasis?

The evidence from lateral cervical cyst studies and knowledge about cystic metastasis of Waldeyer's ring could be applicable for both diagnoses. Terms such as 'branchial cleft cyst' and 'branchial cleft cyst carcinoma' are confusing and misleading, and it is questionable as to whether their usage is still tenable.
