Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient diagnosed in February 2010 with a plasmacytoma of the frontal skull followed by a diagnosis of smoldering myeloma by bone marrow biopsy? See Discussion.
Histology--Heme & Lymphoid Neoplasms: Why did the hematopoietic histology rule change regarding the coding of small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) from the lymphoma code (9670/3) to leukemia (9823/3) when both tissue and bone marrow are involved? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if subsequent to a bone marrow biopsy diagnosis of acute myeloid leukemia there is an oncology consult note that indicates the pathology finding is suggestive of an underlying myelodysplastic syndrome? See Discussion
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed in 2008 with chronic myeloid leukemia, chronic phase and is subsequently diagnosed with both accelerated phase (2010) and blast crisis of CML (2012)? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed on a 3/16/12 lymph node biopsy with diffuse large B-cell lymphoma which was followed on 4/18/12 with bone marrow biopsy diagnosis of follicular lymphoma? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient is diagnosed in 2004 with extranodal diffuse large B-cell lymphoma (DLBCL) of the stomach followed by a 2011 diagnosis of DLBCL involving abdominal lymph nodes? See Discussion.
