**The controversy centres on whether to call all mucinous tumours outside of the appendix ''adenocarcinoma'' - regardless of whether they have [[nuclear atypia|atypia]] & show invasion. | **The controversy centres on whether to call all mucinous tumours outside of the appendix ''adenocarcinoma'' - regardless of whether they have [[nuclear atypia|atypia]] & show invasion. | ||
*Many potential pathways for extraappendiceal spread and peritoneal mucin deposition (pseudomyxoma peritonei) | |||
**A benign mucinous neoplasm ruptures the appendix due to expansion by excessive mucin and the adenomatous epithelium implants into the peritoneum. | |||
**Malignant mucinous glands infiltrate through the appendiceal wall and spread throughout the peritoneum. | |||
**etc. | |||
*''Panarelli and Yantiss'' created a nice summary table - that compares the classifications - see: [http://www.archivesofpathology.org/action/showFullPopup?id=i1543-2165-135-10-1261-t01&doi=10.5858%2Farpa.2011-0034-RA comparison of classifications (archivesofpathology.org)].<ref name=pmid21970481/> | *''Panarelli and Yantiss'' created a nice summary table - that compares the classifications - see: [http://www.archivesofpathology.org/action/showFullPopup?id=i1543-2165-135-10-1261-t01&doi=10.5858%2Farpa.2011-0034-RA comparison of classifications (archivesofpathology.org)].<ref name=pmid21970481/> | ||
