Reportability--Appendix: Is disseminated peritoneal adenomucinosis (DPAM) reportable when it is being referred to as if the primary tumor is a low-grade appendiceal mucinous neoplasm (LAMN)? See Discussion.
Reportability--Appendix: Is the appendix the primary site for a low grade mucinous appendiceal neoplasm (LAMN) with diffuse peritoneal dissemination? See discussion.
Grade, Differentiation--Breast: Should the Bloom-Richardson (BR) grade (low, intermediate, high) have a higher priority than terminology (i.e., well differentiated)? See discussion.
Reportability/Diagnostic Confirmation: If a diagnosis based solely on positive flow cytometry is reportable even if a bone marrow biopsy is negative, how is diagnostic confirmation coded?
Multiple Primaries (Pre-2007)--Breast: How many primaries are to be abstracted when each of multiple breast "re-excisions" performed more than two months apart in 2006 demonstrate intraductal carcinoma and there is no mention of "recurrence"? See Discussion.
