Question:
Reportability--Appendix: Is a metastatic low-grade appendiceal mucinous neoplasm reportable if the pathologist states that it is a borderline tumor of the appendix? See Discussion.
Discussion:
Low-grade appendiceal mucinous neoplasm; Lt ovary, cul-de-sac, omentum, and small bowel: Metastatic low-grade appendiceal mucinous neoplasm. Per pathologist this is a borderline tumor of the appendix.
Answer:
Borderline tumors (other than brain and CNS) are not reportable to SEER. In the case of borderline tumors, the term "metastatic" does not automatically make them reportable. When the "metastatic deposits" are also borderline, the case is not reportable. For this case in particular, the "metastases" are actually (benign) implants and not malignant or invasive mets.
