First course treatment/Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned and how is treatment coded when follicular lymphoma diagnosed in December 2009 is treated with CHOP and a subsequent December 2010 diagnosis of diffuse large B-cell lymphoma is treated with chemotherapy and a bone marrow transplant? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is clinically stated to have Stage III follicular lymphoma following a diagnosis suspicious for B-cell lymphoma and is subsequently diagnosed with large B-cell lymphoma? See Discussion.
Reportability--Heme & Lymphoid Neoplasm: What is the histology code if a myeloproliferative disorder is reportable should a physician suspect this diagnosis and treats the patient? See Discussion.
Reportability/Ambiguous terminology--Heme & Lymphoid Neoplasms: Is a peripheral blood sample with an immunophenotype that is "characteristic of B-cell chronic lymphocytic leukemia" reportable?
Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How is the histology coded when no bone marrow examination is performed but the peripheral blood flow cytometry listed several differential diagnoses and the physician states the diagnosis is small lymphocytic lymphoma? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a right parotid mass shows "MALT Lymphoma with transformation to Diffuse Large B-cell Lymphoma" but the patient has no known history of MALT lymphoma?
Ambiguous terminology/Reportability--Heme & Lymphoid Neoplasms: Should a case be accessioned as MDS, NOS when a consult uses ambiguous terminology (e.g., probable MDS) to describe the disease process and the bone marrow does not confirm the consult diagnosis? See Discussion.
Reportability--Heme & Lymphoid Neoplasms: Is a flow cytometry immunophenotyping of peripheral blood that demonstrates a chronic lymphocytic leukemia (CLL) phenotype reportable as CLL? See Discussion.
