Appendiceal Mucinous Neoplasm with Low Risk of Recurrence
Controversy
- Low grade mucinous neoplasm - WHO proposed alternate name
- Term proposed to encompass mucinous neoplasms with low and high risks of recurrence
- Proposed because all are composed of histologically identical adenomatous appearing epithelium
- We prefer not to combine these processes as their clinical behavior is quite different
- Mucinous neoplasm with low risk of recurrence has very low morbidity and mortality
- Mucinous neoplasm with high risk of recurrence has considerable morbidity and mortality
- Furthermore, the term could be confused with low grade adenocarcinoma
- This is an ordinary colonic type adenocarcinoma, which has a more aggressive course
