Reportability--Lymphoma: Is a lymphoma diagnosed on a bone marrow biopsy reportable if the cytogenetics evaluation performed does not confirm the malignancy? See Discussion.
Reportability/Terminology, NOS--Hematopoietic, NOS: Are the diagnoses "myelodysplastic syndrome," "myelodysplastic syndrome, thrombocytopenia" and "myelodysplastic syndrome, anemia" all reportable to SEER for diagnosis 2001 and later?
Reportability/Histology--Hematopoietic, NOS: Does the presence of sideroblasts on a bone marrow biopsy confirm a diagnosis of refractory anemia with sideroblasts?
Histology/Reportability--Hematopoietic, NOS: Is "drug induced" myelodysplastic syndrome synonymous with "therapy related" myelodysplastic syndrome? If so, would "drug induced" myelodysplastic syndome be SEER reportable and coded with the histology 9987/3?
Multiple Primaries/Histology--Hematopoietic, NOS/Lymphoma: How many primaries are represented and what are the histologies for "B-cell lymphoma with immunophenotypic findings consistent with hairy cell leukemia" found on a bone marrow biopsy? See Description.
Multiple Primaries--Lymphoma: How many primaries should we abstract when Single Versus Subsequent Primaries table indicates one primary but special pathological studies indicate two primaries? See Description.
Multiple primaries--Hematopoietic, NOS: How many primaries should be coded when a patient has multiple occurrences of plasmacytoma followed by a diagnosis of multiple myeloma? See Discussion.
Primary Site/CS Extension--Lymphoma: How are these fields coded for an epidural lymphoma that extends into the bone marrow of the adjacent vertebral body?
