One polyp or two polyps?

This is an interesting looking colonic polyp 
WHAT IS THE LIKELY HISTOLOGY

a) mixed serrated / adenomatous polyp

And that is what it looks like!!!

b) traditional serrated adenoma

But there are TWO components to this polyp!

c) serrated polyp undergoing malignant conversion

Well something has happened but 'lesion' has beautiful crypts!

explanation

Actually, the red bit of the polyp was composed of a tubulovillous adenoma and the rest was a serrated polyp!  In other words, a mixed serrated/adenomatous polyp.  Clearly the famous "three pathways to colorectal cancer": the APC mutation pathway (50%-70%); the mutator “Lynch syndrome” route (3%-5%); and the serrated pathway (30%-35%) can sometime get mixed up !!!
