Question
Reportability--Appendix: Is a pathologic final diagnosis of an appendix with "well-differentiated neuroendocrine tumor (carcinoid)" reportable? See discussion.

Discussion
SINQ 20130027 states that "well-differentiated neuroendocrine tumor" of the appendix is reportable (8240/3) while "carcinoid" tumors of the appendix are not reportable (8240/1). Please explain the difference between "well-differentiated neuroendocrine tumor" of the appendix and a "carcinoid" of the appendix.

Answer
Well-differentiated neuroendocrine tumor of the appendix is reportable. The difference is terminology. "Carcinoid" is listed in ICD-O-3 as a /1 for appendix making it non-reportable.

When both terms are used, ask for clarification from the pathologist. Failing that, accept the reportable terminology and report the case.
