20100077 | Multiple primaries--Heme & Lymphoid Neoplasms: Would it be correct to apply rule M5 for a recurrence and abstract a single primary when a patient has a history of Hodgkin disease diagnosed in 2005 followed by a diagnosis of "recurrent Hodgkin and EBV+ Diffuse large B-cell lymphoma" in 2010? See Discussion. | Does Rule M5 only apply if both diseases are present at the original diagnosis, or does it also take into account a recurrence of an old disease? The answer to this question makes a difference between stopping at rule M5 and abstracting as one disease, or going on to rule M15 to query the Hematopoietic Database to determine whether the patient has two separate primaries.
Example: Patient had Stage II Hodgkin disease in 2005 (all lymph nodes above diaphragm, supraclavicular LN biopsied at diagnosis), treated and patient achieved complete remission. In 2010, the patient is admitted for suspected recurrence. A supraclavicular lymph node biopsy showed, "Recurrent Hodgkin" AND "EBV+ Diffuse Large B-cell Lymphoma," both in the same lymph node. Applying rule M5, this is a single primary and states not to query the DB. However, this doesn't seem correct as it does not account for the new DLBCL. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
You must first determine the histology codes for each occurrence of lymphoma. The 2005 diagnosis was stated to be Hodgkin disease (NOS) [9650/3]. The 2010 diagnosis was Hodgkin and EBV + diffuse large B-cell lymphoma (two histologies). Per Rule M5 the 2010 diagnosis is a single primary because the Hodgkin and the non-Hodgkin (DLBCL) were simultaneously present in the same lymph node. Per Rule PH14, a Hodgkin and non-Hodgkin simultaneously present in the same location should be coded to 9596/3 [B-cell lymphoma, unclassifiable].
Ultimately, there is a diagnosis of 9596/3 in 2010 that followed a diagnosis of 9650/3 in 2005. Per Rule M15, use the Multiple Primary Calculator to determine the number of primaries, which indicates the 9596/3 is a new primary.

20120015 | Diagnostic confirmation--Heme & Lymphoid Neoplasms: How does one determine and code a clinical diagnosis for the diagnostic confirmation in patient diagnosed with essential thrombocythemia? See Discussion. |
The Heme DB originally stated the Definitive Diagnostic Method is coded to 8 [clinical diagnosis only] while an updated version stated it can coded as a clinical diagnosis or it can be based on the results of a bone marrow biopsy or a genetic test. The Abstractor Note section specifies this is a diagnosis of exclusion. According to a recent Web-based training seminar, the JAK-2 diagnosis would be coded 5 [positive laboratory test/marker study]. Doesn't the Definitive Diagnostic Method of a clinical diagnosis/diagnosis of exclusion mean that the diagnostic confirmation of essential thrombocythemia will always be coded as 8 [clinical diagnosis only]? Many people use code 3 for positive bone marrow biopsy and genetics (JAK-2), but the bone marrow is usually reported as only borderline or is stated to be abnormal for a person's age.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the diagnostic confirmation to 8 [clinical diagnosis only] in this case.
Per the Heme DB, JAK-2 is only positive in about 50% of essential thrombocythemia (ET) patients. In addition, a positive JAK-2 test does not identify the type of myeloproliferative disease (MPN) the patient has, only the presence or absence of the JAK-2 mutation.
The WHO guidelines for diagnosing ET are: elevated platelet count over months and the elimination of other causes for an elevated platelet count (such as polycythemia vera (PV), chronic myelogenous leukemia (CML), idiopathic myelofibrosis, or myelodysplastic syndrome (MDS)); the absence of Philadelphia chromosome, BCR/ABL fusion gene; and del(5q), t(3;3)(q21;26),inv(3)(q21q26)).
Subsequently, the physician rules out any underlying causes of thrombocytosis such as an inflammation or infection, other neoplasms, and prior splenectomy.
Ultimately, there is a diagnosis of exclusion. In other words, all other causes for the elevated platelet count have been excluded. The physician assembles the information from the blood counts, bone marrow and JAK-2 testing along with the information that excludes all other diseases and makes a clinical diagnosis of ET.

20120009 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the pathology report states the morphologic features and immunophenotype of a low grade B-cell lymphoma are most compatible with lymphoplasmacytic lymphoma or marginal zone lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9591/3 [B-cell lymphoma, NOS] per Rule PH28 which states that one is to code the histology when the diagnosis is
There is only one non-specific histology code mentioned, low grade B-cell lymphoma. This term is synonymous with B-cell lymphoma, NOS.
Per the Multiple Primaries Calculator, when comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9671/3 [lymphoplasmacytic lymphoma], it is the same primary. When comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9699/3 [marginal zone lymphoma], it is the same primary.

20100100 | Primary site/Histology--Heme & Lymphoid Neoplasms: How are these fields coded for a Langerhans cell histiocytosis diagnosed on an excisional biopsy of the T8 vertebral bone? See Discussion. | The patient had an excisional biopsy of the T8 vertebral bone, but no other tissue biopsy. The doctor confirms the case is malignant. However, Langerhans cell histiocytosis, NOS is listed as /1 (borderline) in the ICD-O-3. | For cases diagnosed 2010 and forward, do not use the ICD-O-3 book to determine the hematopoietic and lymphoid histology codes. Use the Hematopoietic Database and access it at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9751/3 [Langerhans cell histiocytosis] and the primary site for unifocal disease to C412 [bone, vertebral column]. Per Rule PH 30, use the Heme DB to determine the primary site and histology when PH1-PH29 do not apply. Per the Abstractor Notes section in the Heme DB, lytic bone lesions are the most common primary site.

20051127 | Reportability--Brain and CNS: Is an "intradural extramedullary schwannoma (neurilemoma)" of the spine reportable? See Discussion. | Example: Pt underwent laminectomy and excision of intradural extramedullary tumor. Is there a default decision for tumors described as intradural extramedullary tumors, NOS? |
For cases diagnosed 2011 and later: A spinal "intradural extramedullary schwannoma (neurilemoma)" is reportable. This schwannoma originated in the spinal nerve root, C720.

20130134 | Reportability--Heme & Lymphoid Neoplasms: According to the hematopoietic database, systemic mastocytosis is reportable; does that include INDOLENT systemic mastocytosis (which is not listed in the list of alternative names)? |
For cases diagnosed 2018 and forward, indolent systemic mastocytosis is not reportable (9741/1). Smoldering systemic mastocytosis is reportable (9741/3). |

20150050 | Reportability: Is penile intraepithelial neoplasia, differentiated type, reportable? See discussion. |
Foreskin circumcision shows: Penile intraepithelial neoplasia, differentiated type (differentiated PeIN). If reportable, how would the histology and behavior be coded? Is this behavior /2? |
For cases diagnosed 2018 and later Differentiated penile intraepithelial neoplasia (differentiated PeIN), is reportable (8071/2). Please note: Penile intraepithelial neoplasia, grade 3 (PeIN 3) is also reportable to SEER (C600-C609, 8077/2). |

For cases diagnosed 2018 and later HGSIL of the vulva or vagina is reportable. HGSIL is a synonym for squamous intraepithelial neoplasia, grade III. |

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 |
