What are your criteria? How would you define "best"? Of all of those if I was doing dermpath I would rather go to MGH, UCSF, or UVA. I would gouge my eyes out before I went to Ackerman, and would make sure I had a major supply of painkillers before going to NYU because I can't understand a word that Kamino says.
Why did you pick those programs and leave off so many other good ones?
