Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a patient is simultaneously diagnosed with multiple myeloma/plasma cell myeloma, plasmacytoma and plasma cell leukemia?
Reportability--Heme & Lymphoid Neoplasms: Is the term "thrombocytopenia" equivalent to the term "refractory thrombocytopenia" and should be a subsequent primary if it follows a treated diagnosis of pancreatic cancer?
Multiple primaries--Heme & Lymphoid Neoplasms: How many and what primary site(s) are to be accessioned when biopsies of clavicular and neck skin lesions are both consistent with mycosis fungoides? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is histology coded when a bone marrow shows slightly hypercellular marrow with acute myeloid leukemia, non-M3 type and the flow cytometry is also consistent with acute myeloid leukemia, non-M3 type?
Multiple primaries/Histology--Heme & Lymphoid Neoplasms: Is a 2010 diagnosis of ALK+ anaplastic T cell lymphoma following a 2008 diagnosis of follicular B cell lymphoma, grade 1 a new primary? If so, how is the histology coded? See Discussion.
Multiple primaries/Histology--Heme & Lymphoid Neoplasms: Should a single primary be accessioned with the histology coded 9732/3 [multiple myeloma] when a patient is diagnosed initially with a plasmacytoma on an excision and a single bone marrow biopsy showed only 4% plasma cells, then the subsequent workup led to a clinical diagnosis of multiple myeloma? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a bone marrow biopsy shows myelodysplastic syndrome - refractory anemia with excess blasts type 2 (RAEB-2) and myelofibrosis? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient has 2005 diagnosis of multiple myeloma diagnosed returns in 2010 with extramedullary plasmacytoma and a bone marrow biopsy showing plasma cell dyscrasia that is clinically stated to "consistent with a relapse of myeloma"? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient has a history of chronic myelomonocytic leukemia and a 12/08/2011 subsequent biopsy of the left leg that confirms leukemia cutis? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2008 diagnosis of extralymphatic follicular lymphoma in the breast is subsequently diagnosed in 2011 with ocular follicular lymphoma? See Discussion.
