Reportability--Heme & Lymphoid Neoplasms: If hemophagocytic lymphohistiocytosis treated with several rounds of chemotherapy is reportable, what is the primary site?
Reportability--Heme & Lymphoid Neoplasms: For cases diagnosed 2010 and later, are idiopathic thrombocytopenia and autoimmune thrombocytopenia reportable?
Multiple primaries--Heme & Lymphoid Neoplasms: Is a new bone marrow diagnosis of acute myelogenous leukemia that follows a 2007 treated diagnosis of a JAK-2 positive polycythemia vera a new primary?
Primary site/Histology--Heme & Lymphoid Neoplasms: Should the primary site and histology codes be updated when a patient with a history in 2005 of a bone marrow diagnosis of chronic lymphocytic leukemia later presents in 2010 with lymph node biopsy diagnosis of small B-cell lymphocytic leukemia?
Primary site--Heme & Lymphoid Neoplasms: What primary site and heme rule applies when a PET scan shows bilateral renal masses, hypermetabolic liver lesions and retroperitoneal lymphadenopathy, a right kidney biopsy was positive for diffuse large B-cell lymphoma, and the bone marrow biopsy was negative? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of multifocal Langerhans cell histiocytosis with involvement of the bone, liver, spleen and retroperitoneum?
Ambiguous Terminology/Histology--Heme & Lymphoid Neoplasms: How are the histology and diagnostic confirmation to be coded when the pathology report's final diagnosis is "plasma cell dyscrasia consistent with plasma cell myeloma" and the physician subsequently states this diagnosis was plasma cell myeloma? See Discussion.
