Status Final References Source 1: 2007 SEER Manual pgs: C-305 Notes: Appendix C Source 2: pgs: Notes: Question MP/H Rules--Colon: What histology would you assign to a single tumor with the histology 'well differentiated mucinous cystadenocarcinoma in a villous adenoma confined to the appendix'? Does rule H4 apply to this diagnosis or should we continue on in the rules to H14 and code the higher histology? Discussion Answer Use rule H4. Stop at the first rule that applies to the case. Rule H4 is the first rule that applies. The polyp rule, H4, comes before many of the other colon rules becuase it is important to know that the malignancy originted in a polyp.
