20130042 | Reportability--Heme & Lymphoid Neoplasms: Is follicular lymphoma in situ reportable? See Discussion. | Parotid mass and intraparotid lymph node biopsy: Follicular lymphoma in situ (see note).
Note: The morphologic findings in conjunction with the results of immunohistochemical stains demonstrate focal follicular lymphoma in situ in a background of reactive follicular hyperplasia. Cytogenetic studies on the parotid mass demonstrated a normal karyotype. FISH analysis for BCL2 and BCL6 gene rearrangements has been requested and will be reported separately. |
Per the Note under Case Reportability Instructions Rule 3 in the Hematopoietic and Lymphoid Neoplasm Manual, do not report in situ [/2] lymphomas. | 2013 |

20130151 | Primary site--Heme & Lymphoid Neoplasms: What is the primary site when a splenectomy shows "T large granular lymphocytic leukemia" and the peripheral blood flow cytometry is negative? See Discussion. | The physician note states there is no evidence of leukemia on peripheral blood. The disease is localized to the spleen. Is the primary site coded to the bone marrow [C421] or can it be coded to the spleen [C422]? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C421 [bone marrow]. Leukemias are coded to the bone marrow per the Heme DB.

20130174 | MP/H Rules/Histology--Breast: Given that the current MP/H rules do not recognize specific types of lobular carcinoma, should the histology for an invasive pleomorphic lobular carcinoma be coded to 8022/3 [pleomorphic carcinoma] or 8520/3 [lobular carcinoma]? See Discussion. | The MP/H rules do not seem to recognize specific types lobular carcinomas. As invasive pleomorphic lobular carcinoma is "a very rare and distinct morphological variant of invasive lobular carcinoma," (ncbi.nim.nih.gov). Is this histology best reflected in code 8022/3 [pleomorphic carcinoma] or 8520/3 [lobular carcinoma]? | Code the histology to 8520/3 [lobular carcinoma].
The 4th Edition of the WHO Classification of Tumors of the Breast now describes five variants of invasive lobular carcinoma. These variants are solid type, alveolar, pleomorphic, tubulolobular, and mixed-type. WHO has not yet proposed new ICD-O codes be assigned to these variants. The upcoming solid tumor (MP/H) revisions will include instructions on coding these variants. |

20130067 | Histology--Heme & Lymphoid Neoplasms: How is histology coded for a pathology report final diagnosis of diffuse large B-cell lymphoma (50%) and follicular lymphoma, 3A (50%)? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to diffuse large B-cell lymphoma [9680/3] per Rule PH11.
Code the histology to 9680/3 [diffuse large B-cell lymphoma] when DLBCL and any other non-Hodgkin lymphoma (follicular lymphoma, grade 3 in this case) are present in the same anatomic location. DLBCL is coded because it is the more aggressive histology.
NOTE: This answer assumes these two histologies are present simultaneously in the same anatomic location. Per Rule M4, this is a single primary.

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 |

20130176 | Reportability--Ovary: Is an adult granulosa cell tumor of the right adnexa reportable if the left adnexa, diaphragm and paratubal tissue are reported to be consistent with metastasis? See discussion. |
Per the pathology report: Right adnexa: adult granulosa cell tumor. Left adnexa: Foci of metastatic granulosa cell tumor in paratubal tissue. Diaphragm smears: consistent with metastatic granulosa cell tumor. Comment: The morphology and immunoprofile of the cellular aggregates in the paratubal soft tissue are consistent with metastatic granulosa cell tumor. |
Based on the information provided, this case of adult granulosa cell tumor is malignant and reportable. According to our expert pathologist consultant, "though granulosa cell tumor NOS/ adult NOS is 8620/1, the presence of peritoneal implants or metastases, and/or lymph node metastases indicates the tumor is malignant, and it should be coded /3."
Note that the presence of implants or metastases does not indicate malignancy in the case of low malignant potential ovarian epithelial tumors. Our path expert explains "in contrast, by convention the behavior of borderline/LMP ovarian epithelial tumors is determined by the ovarian primary, and is /1, even though there may be peritoneal implants/metastases, or metastatic disease in lymph nodes. The treatment may vary in these circumstances, but to my knowledge the decision as to the tumor designation remains based on the primary tumor." |

20130222 | MP/H Rules/Histology--Bladder: How is the histology coded for a single bladder tumor showing invasive urothelial carcinoma with extensive divergent differentiation including small cell carcinoma, micropapillary carcinoma, and squamous cell carcinoma features? See Discussion. | MP/H rules seem to lead to Rule H8 which indicates that one use the numerically higher ICD-O-3 code. If one applies Rule H8, the histology is coded to 8131/3 [micropapillary urothelial carcinoma]. That would ignore the small cell carcinoma, which seems prognostically more significant. | Code the histology to 8045/3 [mixed small cell carcinoma], a combination of small cell with other types of carcinoma. There is currently no rule in the urinary site MP/H Rules for this combination of histologies. This will be included in the next revision of the MP/H Rules. | 2013 |

20130017 | Reportability--Heme & Lymphoid Neoplasms: Is reactive thrombocytosis reportable? See Discussion. |
The doctor's impression: "Thrombocytosis, mild without other obvious hematologic difficulty. I would be most suspicious for early iron deficiency related to her prior menometrorrhagia. Would limit initial evaluation to iron studies, review of peripheral smear, and hepatic profile." | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Reactive thrombocytosis is not reportable and is not an alternative name for essential thrombocythemia [9962/3].
Only the following are listed as alternate names for essential thrombocythemia in the Heme DB:

20130024 | MP/H Rules/Histology--Bladder: How many primaries are accessioned and what rule applies when the patient has a mixed tumor with a urothelial carcinoma, NOS and a more specific histologic type followed by a diagnosis of urothelial carcinoma? See Discussion. |
The MP/H Rules do not specifically cover how to process urothelial carcinomas with a more specific type of carcinoma. Patient 1: Diagnosed in April 2010 with invasive urothelial carcinoma with signet ring features of the bladder. Site and histology are coded as C679 [bladder] and 8490/3 [signet ring cell carcinoma]. In January 2012 a subsequent diagnosis of invasive urothelial carcinoma of the bladder is made [C679, 8120/3]. Patient 2: Diagnosed in November 2009 with invasive papillary urothelial carcinoma with micropapillary and mucinous features of the bladder. Site and histology are coded C679 [bladder] and 8480/3 [mucinous carcinoma]. In April 2012 a subsequent diagnosis of high grade papillary and flat urothelial carcinoma without evidence of invasion is made [C679, 8130/2]. Does rule M9 apply and these are new primaries? |
For cases diagnosed 2007 and later, accession two primaries for each patient, signet ring cell carcinoma of the bladder and invasive urothelial carcinoma of the bladder for patient 1 and mucinous carcinoma of the bladder and non-invasive papillary urothelial carcinoma of the bladder for patient 2. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Urinary MP rules because site specific rules exist for this primary. Start at the MULTIPLE TUMORS module, rule M3. The rules are intended to be reviewed in consecutive order within a module. For both patients, rule M9 applies because the tumors have histology codes that are different at the second (xxx) number. This guideline will be reviewed for the next version of the MP/H Rules. |

20130110 | Reportability--Heme & Lymphoid Neoplasms: Is a diagnosis of "coagulable state" reportable? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
The term "coagulable state" is not reportable. This is not a a neoplasm. The term means capable of coagulating or capable of becoming thick. There are neoplasms, such as polycythemia vera, in which the blood becomes thick; however, you must have an actual reportable diagnosis in order to accession the case.
