Question:

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a 2013 diagnosis of right leg skin nodules, consistent with plasmacytoma/plasma cell myeloma, follows a 3/20/07 biopsy diagnosis of multiple myeloma?

Discussion:

Answer:

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Abstract this case as a single primary. Code the histology to 9732/2 [multiple myeloma].

Review the Abstractor Notes section in the Heme DB for multiple myeloma. It states that in multiple myeloma there is generalized bone marrow involvement and that extramedullary involvement is diagnostic of advanced disease. This is a case of advanced multiple myeloma.
