Question:

Reportability/Histology--Heme & Lymphoid Neoplasms: Is a diagnosis of "small B-cell non-Hodgkin lymphoproliferative disorder" reportable? If so, how is the histology to be coded? See Discussion.

Discussion:

The final diagnosis of a bone marrow biopsy dated 10/99/2010 was "small B-cell non-Hodgkin lymphoproliferative disorder." The differential diagnosis includes atypical small lymphocytic lymphoma/chronic lymphocytic leukemia and marginal zone lymphoma. Mantle cell lymphoma is very unlikely based on BCL1 negativity. Lymphoplasmacytic lymphoma is also excluded due to the absence of a plasma cell component (CD138 negative).

Answer:

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

Yes. The term "small B-cell non-Hodgkin lymphoproliferative disorder" is reportable. Code the histology to 9591/3 [non-Hodgkin lymphoma, NOS] per Rule PH28. When there is a diagnosis of lymphoproliferative disorder and any lymphoma, code the lymphoma histology.

The information in the discussion is reflective of the difficulty in diagnosing hematopoietic and lymphoid neoplasms. The differential diagnosis indicates that a number of possible specific lymphoma/leukemia diagnoses that have been ruled out, which explains why the final diagnosis is non-Hodgkin, NOS.
