Sngl vs Sbsq Prim Lymph & Hem. 02/28/2001

Question:

Multiple Primaries--Lymphoma: How many primaries should be reported when a left tonsil biopsy is diagnosed with marginal zone lymphoma (9699) and a cervical lymph node biopsy is diagnosed with marginal zone lymphoma and grade 3 follicular lymphoma (9699 and 9698)?

Discussion:

Answer:

For cases diagnosed prior to 1/1/2010:

Abstract two primaries: The first is a marginal zone lymphoma of tonsil and the second is a follicular lymphoma of cervical lymph node. According to the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases (the tri-fold chart), marginal zone lymphoma (9699) and follicular lymphoma (9698) are different primaries.

For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
