Patient discussion about cell mass

Q. what is the most accurate pathological test to identify the primary source of a cystic mass in the neck? the mass was removed. Pathologist was unable to identify the source and diagnosed the mass as a branchilogic carcinmoa (which is extremely rare, if exists at all). Therefore, I am looking for the most updated test and examinations that can be applied to blocks of the mass and determine their origin (primary source)

A. Pathologic examinaions under a microscope are the most accurate ones there are, and sometimes even they don't help to identify the cell types. I do not have any other ideas on other tests you can do, and I believe you should follow the treatment your doctors will advise you based on this diagnosis they have made.
