20130172 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what is the histology for each if a bone marrow diagnosis reveals co-existent systemic mastocytosis and a lymphoplasmacytic neoplasm? See Discussion. | 11/7/12 Peripheral blood flow cytometry: small population of clonal CD5- CD10- B-cells consistent with a B-cell lymphoproliferative process.
1/16/13 Bone marrow final diagnosis: co-existent systemic mastocytosis and lymphoplasmacytic neoplasm.
B-cell component of lymphoplasmacytic neoplasm constitutes 20% of bone marrow cellularity and the plasma cell component approximately 20%. The differential diagnosis includes marginal zone lymphoma with plasmacytic differentiation and lymphoplasmacytic lymphoma.
Flow cytometry: kappa monotypic B-cells and plasma cells.
Comment: Co-existence of systemic mastocytosis and mature B-cell lymphoma meets the criteria for Systemic mastocytosis with Associated Clonal Hematological Non-Mast Cell Lineage Disease (SM-AHNMD).
From our physician's progress note: KIT-D816V-positive, CD117+/CD25+ /SM-AHNMD(40% of the nucleated cells as spindled mast cells) but also seemingly two distinct lymphoid neoplasms, a CD5-negative/CD10-negative B-cell lymphoproliferative neoplasm consistent with occupying another 20% of the nucleated marrow space, together with an IgG-kappa-restricted (non-reportable diagnosis) occupying another 20% of the nucleated marrow space (and an accompanying 2.0 g/dl M-spike without hypercalcemia or anemia). |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Under the Alternate Names section of the Heme DB, systemic mastocytosis with Associated Clonal Hematological Non-Mast Cell Lineage Disease (SM-AHNMD) is a synonym for systemic mastocytosis. Per Rule M2, this is one primary. Abstract a single primary when there is a single histology. Code the histology to 9741/3 [systemic mastocytosis].
Per the pathology report, the two diagnoses of systemic mastocytosis and mantle cell lymphoma meet the criteria for SM-AHNMD. The B-cell lymphoma is a symptom/marker of the AHNMD. In systemic mastocytosis with AHNMD, a myeloid or lymphatic malignancy is diagnosed with the SM. The prognosis is usually dominated by the non-mast cell malignancy.

20130221 | MP/H Rules/Multiple primaries--Prostate: How many primaries are accessioned for a diagnosis of metastatic small cell neuroendocrine carcinoma of the prostate following a previous diagnosis of adenocarcinoma of the prostate? See Discussion. | Would a second prostate primary with histology coded to 8041/3 [small cell carcinoma] be accessioned for the following examples? Or are these metastases despite the different histologies?
Example 1: Prostate adenocarcinoma diagnosed in 2001, no treatment given. Metastatic small cell neuroendocrine carcinoma diagnosed 03/2012 on liver biopsy with a physician's statement in 4/2012 that the prostate is likely the cause of the metastasis to the liver.
Example 2: Prostate adenocarcinoma diagnosed in 2006, treated with TURP. Bone marrow biopsy in 5/2012 shows involvement by metastatic small cell carcinoma with morphologic and immunophenotypic features that argue against prostatic adenocarcinoma. The oncologist assessment states, "The patient has Stage 4 small cell carcinoma of the prostate and the bone marrow biopsy path shows metastatic small cell carcinoma (likely prostate in origin)." |
Accession two primaries, adenocarcinoma [8140/3] of the prostate [C619], followed by small cell (neuroendocrine) carcinoma [8041/3] of the prostate [C619] for each of the examples given per Rule M10.
In each case, the second histology (because it is not adenocarcinoma) is a new prostate primary. Small cell carcinoma and small cell neuroendocrine carcinoma are not adenocarcinomas. As a result they are not covered by Rule M3. |

20130129 | Histology--Heme & Lymphoid Neoplasms: How is histology coded for a diagnosis of composite lymphoma (follicular lymphoma and small lymphocytic lymphoma, BCL-2 positive)? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL)] per Rule PH15. Code the histology to the non-Hodgkin lymphoma (NHL) with the numerically highest ICD-O-3 code when two or more NHLs are present in the same present in the same lymph node(s) or lymph node region(s), tissue(s), organ(s), or bone marrow. Both follicular lymphoma [9690/3] and SLL [9823/3] are types of NHL. Therefore, the histology is coded to 9823/3.
This composite histology represents a single primary per Rule M4. The rule states to abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s).

20130209 | 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? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Per Rule M10, abstract two primaries. Per the Heme DB, polycythemia vera [9950/3] transforms to an acute myelogenous leukemia [9861/3]. According to Rule M10, one is to abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm (e.g., polycythemia vera) AND there is a second diagnosis of an acute neoplasm (e.g., acute myelogenous leukemia) more than 21 days after the chronic diagnosis.

20130157 | Primary Site--Heme & Lymphoid Neoplasms: What primary site code should be assigned and what rule justifies that code?
Scenario: Pleural effusion, underwent thoracentesis. Pleural fluid unexpectedly showed Large B-Cell Lymphoma. Extensive workup including CT & PET was done and all findings were within normal limits. No evidence of lymphoma was seen and no palpable adenopathy was found. The only indication of lymphoma was the malignant pleural effusion. |
Code to pleura, C384.
Per the Hematopoietic database, Diffuse Large B-Cell Lymphoma can originate in the pleural cavity. |

20130194 | Reportability--Brain and CNS: Are blood vessel tumors arising in CNS sites reportable? See Discussion. |
Previous instructions from the CDC (Cancer - Collection and Coding Clarification for CNS Tumors - NPCR) stated that non-malignant blood vessel tumors in CNS sites are reportable and should be coded to the CNS site in which they arose. SINQ 20081113 also states that a blood vessel tumor, cavernoma/cavernous hemangioma, in the brain is reportable. However, SINQ 20120034 contradicts this previous answer stating the site should be coded to C490 [blood vessel] for a blood vessel tumor (venous angioma) in the brain. If blood vessel tumors arising in a CNS site are no longer reportable, please specify the site/histology codes for these non-reportable tumors and when this change took place. |
Vascular tumors of the CNS are reportable when they arise in the dura or parenchyma of the CNS and should be coded accordingly. The instructions in the CDC book regarding primary site coding are not the most current instructions.SEER assumed responsibility for brain and CNS reporting instructions in 2007. The tumor in SINQ 20120034 is not reportable because it arises in a blood vessel. The cavernous hemangioma in SINQ 20081113 is reportable because the primary site is the white matter of the cerebral cortex. |

20130022 | Reportability--Melanoma: Is "early" melanoma reportable? See Discussion. |
Because "evolving" melanoma was never reportable, this issue only relates to "early" melanoma. |
For cases diagnosed 2018 to 2020, early or evolving melanoma is not reportable. Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. The tumors may be described as "proliferation of atypical melanocytes confined to epidermal and adnexal epithelium," "atypical intraepidermal melanocytic proliferation, "atypical intraepidermal melanocytic hyperplasia"; or "severe melanocytic dysplasia." Not reportable. Melanoma Solid Tumor Rules, 2018, page 3, https://seer.cancer.gov/tools/solidtumor/Melanoma_STM.pdf |

20130043 | Reportability--Heme & Lymphoid Neoplasms: Is reactive plasmacytosis a reportable diagnosis that is equivalent to plasmacytoma? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Reactive plasmacytosis is not reportable unless there is another indication of a reportable neoplastic disease. Reactive plasmacytosis is "a well known pathological process described as occurring in a variety of situations including infections, autoimmune disease, diabetes mellitus, sideropenia, liver cirrhosis and neoplastic conditions including leukemia. This process, by definition, is assumed to be a reaction of the immune system to an unknown or poorly defined stimulus." Based on this definition, reactive plasmacytosis is not the same as a plasmacytoma, although it may indicate the presence of a neoplastic process, such as leukemia.
