Okay, so now I understand why the J's RO didn't want me asking questions about the pathology report!!!
I did enough research on-line to find that 
HPV will show up in Branchial Cleft Cysts which makes it much harder to diagnose a SCC HN from a BCC (which, by virtue of its name, IS a neck issue.) It is either a benign congenital cyst or it is oral cancer. Could there be a worse differential diagnosis? 
I was thinking, in error, that p16 positivity and 
HPV+ status were interchangeable.  It is very confusing.  There is 
HPV+, there is also having an active 
HPV virus, and there is p16 positivity.  I know the test for the presence of 
HPV is indicated by a p16 cell stain.  So...since I am now on the good ship Confusion...and have made sure everyone is invited along for the cruise...I'll stop trying to figure it out now!  I need a Motrin....  :S
