Intestinal Adenocarcinoma, Intrapolypoid
Occassionally we surgical pathologists are presented with a colorectal polyp which turns out to have intrapolypoidal adenocarcinoma. What is clinically done following such a diagnosis depends on tumor grade, vascular invasion status, Haggitt level of polyp invasion, and degree of closeness of the surgical margins. Some...for example, AFIP3...would consider level 0 to be high grade dysplasia, with WHO ambivalent, and AJCC as pTis3.
