I hope the question was clear because I have got nothing to clarify it with. I was reading Robbins and its Neoplasia chapter when that confused me a bit. Can anybody clear this up for me? According to Robbins:
Papillomas are benign epithelial neoplasms growing on any surface, that produce microscopic or macroscopic fingerlike fronds.
A polyp is a mass that projects above a mucosal surface... to form a macroscopically visible structure.
I understood these sentences quite good enough but what is the fundamental quality that sets them apart? I still am not confident regarding their differences (and cannot differentiate them, say, on a patho slide) A little bit of histology here would be really helpful.
