Multiple primaries/Histology--Lymphoma: How many primaries should be abstracted and how should the histology field(s) be coded in this situation?

How would the bone marrow involvement by only NHL be handled? Composite lymphoma (9596) as defined by SEER and ICD-O is NHL and HD in one node which fits the final impression on the removed cervical node. See Discussion.
20061010 Multiple Primaries/Histology--Lymphoma: If an oral mucosa, right hard palate biopsy contains a composite lymphoma [low-grade follicular + chronic lymphocytic leukemia], how many tumors should be abstracted and how should the histology field(s) be coded?

Multiple primaries--Lymphoma: Is a splenectomy done for non-Hodgkin lymphoma diffuse large B-cell of the spleen a composite histology and a single primary if a perihilar lymph node with Hodgkin lymphoma classic type is found at the time of this surgery?

Histology--Hematopoietic, NOS: Because histology 9895/3 [Acute myeloid leukemia with multilineage dysplasia] was recognized as a distinct entity by WHO with too few cases of the subtypes [with or without prior MDS] to warrant separate histology codes for each, should the wording for the non-bold definitions in ICD-O-3 be changed to the following in both the alpha and numeric sections? See Description.

AML with multilineage dysplasia and prior MDS

AML with multilineage dysplasia and without prior MDS
20081004 First course treatment/Histology--Lymphoma: What treatment, if any, is coded for a patient with methotrexate induced lymphoma when the treatment plan is to take the patient off methotrexate? Also, is there a specific histology for drug induced lymphoma? See Discussion.
20091105

Multiple Primaries--Hematopoietic: How many primaries and which histologies should be reported for a case presenting with a 2005 diagnosis of CLL/SLL, 2006 clinical diagnosis of MDS and a 2008 diagnosis of AML? See Discussion.
20031036 Histology--Hematopoietic, NOS: When both the path and clinical diagnoses simultaneously reflect reportable diagnoses but one is a worse form of the same disease process, which diagnosis do we code? See Description.
20071110 Reportability--Hematopoietic, NOS: The Abstracting and Coding Guide for the Hematopoietic Diseases, page 47, states to determine whether the physician is using the term myelodysplasia to describe bone marrow marrow malfunction or a neoplasic syndrome in order to determine reportability. What do we do when there is no information one way or the other?
20031200 Reportability/Terminology, NOS--Hematopoietic, NOS: Is "smoldering" multiple myeloma reportable to SEER?
20031033 Grade, Differentiation--Hematopoietic: Is this field coded to 6 [B-cell] from a flow cytometry that specifies the percentage of B-cells that exist within the percentage of lymphoid cells in the bone marrow biopsy? See Description.
