Discussion:
Patient has colonoscopy with excision of small 5mm polyp in rectum (no mention of anus or anal canal); path reads out: AIN-3 (anal intraepithelial neoplasm grade 3).
In coding the histology using the "Other Sites" rules, H2 would be the first rule that applies for this case. However, we lose the fact that the AIN-3 arose in a polyp (H3). Is this how SEER wants these cases coded?
