#The phrase "negative for [...] malignancy" is also recommended in the Canadian consensus. This is not endorsed | #The phrase "negative for [...] malignancy" is also recommended in the Canadian consensus. This is not endorsed by [[onlinepathology]], as one very frequently does not get submucosa. It is like reporting "negative for muscularis propria invasion" on a urinary bladder biopsy without muscularis propria. Further, the guidelines are inconsistent in that they do not advise "negative for dysplasia and malignancy" for [[SSA]]s. If there is clinical suspicion of an invasive malignancy, it is useful to comment that no submucosa is present. | ||
