The type of polyps associated with UC are pseudopolyps, as opposed to the adenomatous polyps associated with precancer (the type that are on a stalk with precancerous cells in them). These are called pseudopolyps because they are not true polyps, but inflammatory tissue caused by the raised edges of ulceration and overgrowth of granulation tissue. So, no, these are not "fake" polyps and it is an actual medical term.
John, I am not sure what sort of polyps your doctor found in the previous 8 years, and I would be concerned if they were of the adenomatous type, instead of the more typical inflammatory pseudopolyps. Is it possible that this was a different doctor (describing the same thing differently) or perhaps a different description on the pathology report? Because, yes, there are different types.
