Multiple primaries--Heme & Lymphoid Neoplasms: Is a 10/2010 diagnosis of accelerated phase of CML following a 4/2010 diagnosis of blast phase CML a new primary? See Discussion.
Reportability/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned and how is histology coded when a patient has a history of chronic myelogenous leukemia diagnosed in 1997 and a "blast crisis with myeloid markers" of this disease in 2010? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when bilateral breasts are involved with MALT lymphoma and the bone marrow is negative?
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a bone marrow shows low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported when a solitary plasmacytoma diagnosed in 2010 (T spine) is followed by another solitary plasmacytoma (L spine, different primary site) in 2013? See Discussion.
Histology/Primary site--Heme & Lymphoid Neoplasms: How is the primary site and histology coded when a bladder biopsy reveals myeloid sarcoma and a simultaneously performed bone marrow biopsy demonstrates acute myeloid leukemia? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How do you code the primary site for a marginal zone lymphoma involving bilateral axillary lymph nodes and inguinal lymph nodes, bone marrow and bilateral orbits that the physician refers to as a bilateral orbital lymphoma, Stage IV? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: What rule applies to code a primary site for a peripheral blood diagnosis of marginal zone lymphoma that has a positive flow cytometry/FISH analysis when no biopsies are performed, scans show no evidence of disease, exam indicates no lymph nodes are palpable and the physician's clinical diagnosis "marginal zone lymphoma, unspecified site, stage 1"? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is this field coded when the final diagnosis for excisional biopsy of two cervical lymph nodes shows classical Hodgkin lymphoma, histologic subtype cannot be determined, but the COMMENT section of the report indicates there are features of both lymphocyte rich and nodular sclerosis subtypes?
Primary site--Heme & Lymphoid Neoplasms: What is the primary site for a bone marrow biopsy positive for systemic mastocytosis that also involves the spleen and lymph nodes with associated leukocytosis, mild anemia and thrombocytopenia?
