20200019 | Diagnostic confirmation--Heme and Lymphoid Neoplasms--Lymphoma: Is Diagnostic Confirmation "5" for Hematopoietic Neoplasms appropriate for this case? There appears to be no conclusive histologic diagnosis (Neoplasm, suggestive of lymphoma) and only the IHC/flow cytometry issued a conclusive diagnosis. See Discussion. |
10/4/2018 Frozen Section Diagnosis: Brain tissue with atypical cells and inflammatory cells, defer to permanents for further evaluation. Note: Tissue for flow cytometry is submitted. Final Diagnosis: Preliminary Diagnosis: Brain Tumor, Biopsy: Neoplasm, suggestive of lymphoma (see comment). Comment: The tumor exhibits nuclear atypia and increased mitosis. The tumor cells are immunologically positive for LCA and with very high ki67 labeling index. GFAP and synaptophysin are not expressed by tumor cells. The above suggests a lympho-proliferative process. This case is forwarded to the hematopathology service of this department for further evaluation. The final diagnosis report will be issued by the hematopathologist as an addendum. Supp Rpt Add Addendum Diagnosis: The brain biopsy showed brain tissue large lymphoid cell infiltrate. Additional immunohistochemical stains are performed. The large cells are positive for CD20, BCL2, BCL6 (subset), MUM1, and CD30, negative for CD3, CD5, and CD10. Staining for c-MYC is negative. Ki-67 positive large cells are approximately 18%. EBER is strongly positive by ISH. Diagnosis: Brain lesion, biopsy: EBV+ Diffuse Large B-cell Lymphoma. Addendum Comment: The concurrent flow cytometric study showed monoclonal lambda-positive B-cells without out CD5 and CD10 expression, consistent with B-cell lymphoma. |
Assign Diagnostic Confirmation as code 3, positive histology plus positive immunophenotyping. The biopsy diagnosis demonstrated EBV+ diffuse large B-cell lymphoma, with positive staining as indicated in the Hematopoietic and Lymphoid Neoplasm Database.The information received from the additional studies confirm the more specific diagnosis. |

20190039 | Solid Tumor Rules (2018)/Histology--Lung: What is the histology code of invasive moderately differentiated adenocarcinoma, predominantly papillary subtype, with minor acinar and lepidic subtypes? See Discussion. |
11/01/2018, lung, left upper lobe, wedge resection: Invasive moderately differentiated adenocarcinoma, predominantly papillary subtype, with minor acinar and lepidic subtypes. Would this be 8260/3 since the acinar and lepidic subtypes are described as minor or would this be 8255/3 because there is papillary plus two other subtypes/variants described as subtypes? |
Code as adenocarcinoma, papillary predominant (8260/3) according to the Lung Solid Tumor Rules, Coding Multiple Histologies, which says to code the specific histology. The most specific histology may be described as component, majority/majority of, or predominantly, where predominantly describes the greater amount of tumor. |

20220012 | EOD 2018/Lymph Nodes--Corpus Uteri: Are lymph nodes found on imaging post-surgery included in Extent of Disease (EOD) Regional Nodes if surgery is already completed? See Discussion. |
11/16/20: Patient diagnosed with endometrial cancer on by MRI of the pelvis; 11.5 cm uterine mass consistent with cancer with no lymphadenopathy. 1/6/21: Patient had a total abdominal hysterectomy/bilateral salpingo-oophorectomy and pelvic lymph node dissection. Operative report stated patient had mildly enlarged bilateral pelvic nodes. Path report: Endometrioid adenocarcinoma with invasion of the serosa. Five bilateral pelvic nodes were sampled and negative. Originally, staging had patient as node negative. 1/22/21: Patient had post op imaging done that showed metastatic retroperitoneal, aortocaval, and possibly left iliac lymph nodes. Physician changed staging to include the lymph node involvement. |
EOD includes all information available within four months of diagnosis in the absence of disease progression or upon completion of surgery(ies) in first course of treatment, whichever is longer. Since the imaging was within the four-month window, and the nodes could have been positive during surgery but not assessed by the surgeon, use the information from the imaging. Assign code 600 for EOD Regional Nodes for involvement of the aortocaval and retroperitoneal nodes (para-aortic nodes), size unknown. |

20200055 | Solid Tumor Rules (2018)/Multiple primaries--Melanoma: Should a case with treatment delayed due to COVID-19 be abstracted as one or two primaries? It is uncertain if the invasive tumor would be a new tumor, or deeper extension/disease progression from the original tumor. See Discussion. |
11/18/2019 Left 1st Digit/Thumb Biopsy: Atypical Melanocytic Proliferation consistent with Early Acral Lentiginous Melanoma in situ. Margins Positive. (Not a reportable diagnosis for 2019.) 12/5/2019 Left 1st Digit Shave Biopsies: Malignant Melanoma in situ. Margins Positive. 1/15/2020 Started Aldara (treatment plan: use for ~3 months then Mohs/excision, but due to COVID could not get resection until 7/2020). 7/29/2020 Left Thumb Excision: Residual Melanoma in situ. Margins Positive. Treatment Plan: re-excision. 8/6/2020 Left Thumb Re-Excision: Atypical Lentiginous Melanocytic Proliferation at the 12-2 margin may represent the advancing edge of melanoma in situ. (8/19/2020 Plan to treat the 12-2 margin as positive with in situ; plan for re-excision). 8/20/2020 Left Thumb Re-Excision & Left Nail Plate Excision: Malignant Acral Lentiginous Melanoma with extensive melanoma in situ. Breslow 1.3mm. Margins Positive. Nail plate & bed epithelium with hemorrhage and a mild increase in melanocyte density likely represent melanoma in situ. 9/4/2020 Left thumb partial amputation & Left axillary Sentinel Lymph Node Excision: Residual Malignant Melanoma in situ. 0/3 sentinel nodes positive. |
Abstract a single primary using the Solid Tumor Rules for melanoma. Report this melanoma as invasive (/3) as documented in the information from 8/20/2020. The treatment delay does not influence the number of primaries to be reported. Registries in SEER regions: Report the COVID-related information as directed in the COVID-19 Abstraction Guidelines, https://seer.cancer.gov/tools/covid-19/. |

20051139 | Date of Diagnosis--Lung: Should the diagnosis date be coded to the date of the scan or the date of the resection when there is a negative biopsy that occurs between the two procedures? See Discussion. | 11/2003 CT chest: 2 cm LLL mass should be considered carcinoma until proven otherwise. 2/2004 CT Chest: stable LLL mass still consistent with primary or metastatic lung neoplasm 11/2004 CT chest: LLL mass suspicious for slow growing carcinoma 3/2005 FNA L lung: atypical cells 4/2005 L lobectomy: well-diff adenocarcinoma |
Code the date of diagnosis as 11/2003. A clinical diagnosis was made on 11/2003 and this is the earliest date of diagnosis for this case. | 2005 |
|
20210005 | Reportability/Histology--Ovary: Is a 2020 ovary case reportable with the positive malignant findings in adnexal cystic fluid and peritoneal washing? See Discussion. |
11/24/20 Adnexal mass, cyst fluid: Positive for malignant cells. Clusters of inhibin-positive, CK7-negative cells, consistent with adult granulosa cell tumor cells. Groups of inhibin-negative, CK7-positive epithelial cells consistent with serous borderline tumor cells. Peritoneal washing: Positive for malignant cells. Small groups of inhibin-positive, CK7-negative cells, consistent with adult granulosa cell tumor cells. A. Left ovarian mass: Adult granulosa cell tumor (AGCT) of ovary (see note). pTNM Stage: pT1c3 pNX - Serous borderline tumor (SBT) of ovary (see note). pTNM Stage: pT1a pNX. Fallopian tube; unremarkable. B. Right ovary: - Serous cystadenofibroma of ovary. Fallopian tube; unremarkable. C. Left pelvic wall nodule: Fibro-calcified nodule, consistent with necrotic appendix epiploica. D. Uterus (hysterectomy): Uterine leiomyomas. Endosalpingiosis of uterine serosa and paracervical tissue. Atrophic endometrium. Note: The left ovarian mass is involved by a combined adult granulosa cell tumor and a serous borderline tumor. The AGCT mainly involves the thick-walled cystic area while the SBT the thin-walled cyst/s. The 2 neoplastic elements do, however, demonstrate areas of intimate and close intermingling. From the current literature, it appears that, based on FOXL2 mutation, the AGCT component of combined AGCT and ovarian epithelial tumors is either a true neoplastic processes or an AGCT- like proliferation morphologically indistinguishable from AGCT. To further evaluate the nature of the AGCT component, a FOXL2 analysis is in progress and an addendum will follow. |
For cases diagnosed prior to 2021, report adult granulosa cell tumor of ovary only when stated to be malignant or when metastases are indicated, as by the positive peritoneal washings for this 2020 case. Beginning in 2021, report all cases of adult granulosa cell tumor of ovary based on ICD-O-3.2. |

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.

20140082 | MP/H Rules/Histology--Testis: How should histology be coded for a testicular teratoma with somatic type malignancy (adenocarcinoma)? See discussion. |
11/8/2013 Rt orchiectomy: teratoma with somatic type malignancy (adenocarcinoma). 5/2/2014 Abdominal mass excision: metastatic teratoma involving matted lymph nodes. Patient age at diagnosis is 31.
Per web search, a teratoma with somatic type malignancy is a rare type of tumor. Should the histology be coded to 8140/3? This seems to conflict with SINQ 20120085, which indicates a testicular mature teratoma in an adult is malignant, and in this example, it was also the portion of tumor that metastasized. |
Assign code 9084/3, listed in ICDO as teratoma with malignant transformation.
Our expert pathologist consultant states that this is a very rare situation. The non-germ cell components are believed to arise out of the teratoma portions, and are seen in only of few percent of teratomas. They are given the designation "teratoma with somatic type malignancies" (WHO). |

20200061 | Solid Tumor Rules (2018)/Histology--Bladder: A patient has high-grade papillary urothelial carcinoma with focal glandular and neuroendocrine differentiation followed by carcinosarcoma. Is this one or two primaries? See Discussion. |
12-19-19 Transurethral resection of bladder tumor pathology revealed high-grade papillary urothelial carcinoma with focal glandular and neuroendocrine features; Pathology Overread: High-grade papillary urothelial carcinoma with focal glandular and neuroendocrine differentiation. Carcinoma invades muscularis propria pT2. Histology 8130 01/20/20 to 07/01/20, completed 6 cycles of gemcitabine/cisplatin. 07/30/20 Robotic radical cystoprostatectomy with bilateral pelvic lymph node dissection, open ileal conduit pathology revealed carcinosarcoma, invading perivesical fat, no lymphovascular invasion, negative margins. ypT3bN0M0 disease; Pathology Overread: Carcinosarcoma arising in association with high-grade papillary urothelial carcinoma. Histology 8980/3 or is there another histology that should be used? |
The carcinosarcoma is a separate tumor, abstract a new primary per M13. Code this primary to 8980/3. Based on the information provided, the patient was first diagnosed with papillary urothelial carcinoma and received neo-adjuvant treatment for that specific histologic type. Subsequent resection identified carcinosarcoma arising within the papillary neoplasm. Carcinosarcoma is rare in bladder primaries and is not included in Table 2; however, it is a subtype/variant of sarcoma. |

20041078 | Ambiguous Terminology: Is the expression "has the markings of a malignancy" a clinically reportable term? See Discussion. |
12/02 Baseline mammogram: spiculated mass with associated marked retraction located in UOQ lt breast. This has the markings of malignancy. Several microcalcifications in outer aspect of rt breast. BI-RADS 5 higly suggestive of malignancy. |
Do not accession cases using only the term "has the markings of malignancy." This term is not on the list of ambiguous terms that are reportable. If the term does not appear on either the reportable or not reportable list, the term is not diagnostic of cancer. Do not accession the case. Please see SINQ 20010094 in reference to BI-RADS terminology. |
