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. |

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. |

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. |

20180047 | Reportability--Kidney: Is a hybrid oncocytic tumor reportable? See Discussion. |
10/27/2017 partial nephrectomy final path diagnosis: renal oncocytic neoplasm, favor hybrid oncocytic tumor. Comment: |
Do not report renal HTOC. According to our expert pathologist consultant, "the genetic studies seem to indicate that the chromosomal changes of chromophobe renal carcinoma are not found in the hybrid tumors." |

20240056 | Reportability/Histology--Heme & Lymphoid Neoplasms: How should this unusual 2023 pathology-only case be reported and coded for leukemia cutis? See Discussion. |
10/25/2023: Patient presents to dermatology office with a questionable drug eruption having 3 weeks of papular eruptions of Trunk (Left Chest). Punch biopsies were taken that came back as immature hemopoietic infiltrate with monocytic differentiation. Comment: Myelodysplastic syndrome and leukemia cutis are possibilities. Addendum Report: Additional stains were prepared. ERG is strongly positive. CD1a and S100 do not stain the atypical cells.The controls stain appropriately. CD123 perform with appropriate control is also negative. The pattern is that of so-called "leukemia cutis" which could be seen in the clinical setting of myelodysplasia, chronic myelomonocytic leukemia (CMML) or precursor to acute myelomonocytic leukemia (AMML). Recommend work up. The only available information at present is a diagnosis of leukemia cutis, and that there was no prior history of a hematological malignancy in this patient. |
Report this case of leukemia cutis and code to bone marrow (C421) and leukemia NOS (9800/3) based on the information provided. Update the abstract if new information becomes available. Leukemia cutis is the rare infiltration of neoplastic leukocytes into the epidermis, dermis, or subcutis from an existing leukemia that results in clinically identifiable cutaneous lesions. Leukemia cutis may precede, follow, or occur concurrently with the diagnosis of systemic leukemia. It is an advanced phase of the leukemia having a poor prognosis that also strongly correlates with additional sites of extramedullary involvement. This can alter the appropriate treatment regimen for a patient. It is a type of "metastasis" or spread of the leukemia cells. The "conventional" definition for leukemia cutis is the infiltration of skin from a bone marrow primary. It is most often diagnosed via skin biopsy—punch, shave, etc., utilizing IHC/biomarker testing and is commonly associated with CMML and acute myeloid leukemia (AML). As such, it a reportable condition especially when preceding a confirmed systemic leukemia diagnosis. In this situation, the diagnosis date would be the date of the positive leukemia cutis skin bx—punch, shave, etc. The case should be coded to C421; 9800/3 Leukemia NOS until the official systemic leukemia diagnosis is rendered. If possible, follow back should be conducted to determine the specific systemic leukemia histology (CMML; AML) and the treatment received. If the leukemia cutis follows or occurs concurrently with the diagnosis of a systemic leukemia, it is NOT a separate primary but merely an advanced stage of the systemic leukemia diagnosis. |

20000433 | Diagnostic Confirmation: Is it appropriate to code this field to "radiography" confirmation when a CT scan does not actually contain a diagnosis of malignancy, however, the discharge diagnosis in the medical record of "probable malignancy" is likely based on the abnormal CT findings? See discussion. | 10/1/02 CT of Chest: 1) Huge (left) suprahilar mass. 2) Moderate volume loss, left lung. Appearance suspicious of LLL collapse. An infiltrate is seen in the aerated upper lobe as well as pleural effusion. 3) Streaky and nodular changes are noted at the right base that may represent possible lymphangetic spread of tumor.
10/23/02 Discharge Dx: Lung mass, probably carcinoma. |
Code the Diagnostic Confirmation field to 7 [Radiography]. This is appropriate because it was the scan evidence that was used to make the clinical diagnosis. | 2000 |

20130138 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2010 diagnosis of a preleukemic condition is subsequently diagnosed in 2012 with a specific leukemia that is not listed as a transformation? See Discussion. |
10/02/10 bone marrow biopsy showed myelodysplastic syndrome, unclassified [9989/3]. 6/19/12 bone marrow biopsy showed chronic myelomonocytic leukemia (CMML-2) [9945/3]. CMML-2 is not listed as an acute neoplasm for MDS. Is this the same disease? Per the pre-2010 rules, this would be the same disease. The current Heme DB indicates these are separate primaries. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case should be accessioned as two primaries, myelodysplastic syndrome (MDS) [9989/3] diagnosed 10/2/10 and chronic myelomonocytic leukemia (CMML-2) [9945/3] diagnosed 6/19/12 per Rule M15. Per Rule M15, use the Multiple Primaries Calculator when rules M1-M14 do not apply. When myelodysplastic syndrome (MDS) became reportable, the rules in effect at that time resulted in MDS often being the only diagnosis reported when both MDS and a leukemia were diagnosed. Statistics for some leukemias were impacted. Now we report both the MDS and the leukemia for greater accuracy. SEER*Educate provides training on how to use the Heme Manual and DB.

20100075 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned when a 1/27/10 bone marrow biopsy, FISH and cytogenetics reveals chronic myelogenous leukemia (CML), BCR/ABL positive, t(9;22)(q34;q11) and a 4/15/10 bone marrow biopsy reveals B-acute lymphoblastic leukemia (Blast phase of CML)? | 1/27/10 BM biopsy: CML BCR/ABL+ FISH positive for BCR/ABL and cytogenetics showing the t(9;22)q34q11.2 translocation. Treated with Imatinib. 4/15/10 BM biopsy: B-acute lymphoblastic leukemia (Blast phase of CML). Would the term "blast phase of CML" indicate the 4/15/10 bone marrow biopsy showed CML or would a new primary be abstracted with histology coded 9811/3 [B lymphoblastic leukemia/lymphoma, NOS]?
Applying rule M10, this is a new primary, but note 2 states transformations are defined in the Heme DB. The Abstractor Notes section indicates CML has three phases: chronic, accelerated, and the blastic phase or blast crisis. The accelerated phase can last weeks to months. In the chronic phase the involvement is usually limited to blood, bone marrow and spleen although the liver may be infiltrated. During the blastic phase, lymph nodes and tissue may be involved. The blastic phase is a disease progression from the chronic phase. The disease, however, remains the same histology, chronic myelogenous leukemia. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case represents a multiple primary per Rule M15 which states you are to use the Heme DB Multiple Primaries Calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14.
The histology for the first primary is coded to 9875/3 [chronic myelogenous leukemia, BCR-ABL1 positive].
The histology for the second primary is 9811/3 [B lymphoblastic leukemia/lymphoma, NOS] in the absence of further documentation that the B-ALL was also positive for the t(9;22) translocation.
The histology code 9806/3 [Mixed phenotype acute leukemia with t(9;22)(q34;q11.2); BCR-ABL1] cannot be used for the second primary because there is no documentation that the B-ALL diagnosed on 04/15/2010 also had the t(9;22) translocation and this histology cannot be used in patients ." Per the Definition section in the Heme DB, in order to use histology code 9806/3 "This leukemia meets the criteria for mixed phenotype acute leukemia (MPAL) in which the blasts also have t(9;22) translocation of BCR-ABL1 rearrangement. Some patients with chronic myeloid leukemia may develop or even present with a mixed blast phase that would meet criteria for MPAL; however, this diagnosis should not be made in patients known to have had CML."

20091036 | CS Mets at DX/CS Extension--Ovary: Is carcinomatosis always captured in the CS Mets field? Can the term carcinomatosis be used to describe peritoneal implants as well? See Discussion. | 1/18/06 CT guided biopsy of abdominal mass & ant peritoneum nodule: Extensive carcinomatosis affecting the paracolic gutters, liver surface & pelvis. 6 cm tumor mass was visibly engulfing the small bowel & tube; poorly differentiated adenoca, mullerian derived, shows attributes of clear cell carcinoma, high grade (FIGO III), 2.5 cm size, does not involve fallopian tube. R&L abdominal wall & mesentery, mets adenoca. 5/31/06: tumor debulking with right salpingo-oophorectomy. Final DX: Poorly differentiated adenocarcinoma, clear cell type, right ovary (FIGO III), stage IV per MD. |
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.In the case of ovarian cancer, the term carcinomatosis may refer to peritoneal implants, especially when the implants are numerous. It does not refer to distant metastases in this context. This issue has been forwarded to the CS version 2 committee. |

20130161 | Primary Site--Heme & Lymphoid Neoplasms: Is the primary site coded to C779 or C421 for a bone marrow that is positive for B-cell acute lymphoblastic leukemia, the peripheral blood demonstrates leukemic involvement and the PET scan shows involvement of abdominal lymph nodes, spleen and throughout the bones? See Discussion. | 1/11/13 Bone marrow bx: B-cell acute lymphoblastic leukemia. Flow cytometry of peripheral blood shows leukemia involvement.
PET scan shows involvement of abdominal lymph nodes, spleen and throughout the bones. The patient has an elevated WBC, anemia and thrombocytopenia.
The answer to SINQ 20120047 (which is no longer visible in the system) said to code B lymphoblastic leukemia/lymphoma to bone marrow for primary site if there is bone marrow involvement. The Heme/Lymph Manual Rule PH7 says to code bone marrow as the primary site if bone marrow is the only site involved.
Following the manual, the primary site would be C779. However, according to the answer to SINQ 20120047, the primary site would be C421. Which is correct? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per the Heme DB, the histology B-cell acute lymphoblastic leukemia is synonymous with B lymphoblastic leukemia/lymphoma, NOS. Per Rule PH8, for a neoplasm that can manifest as either leukemia lymphoma or leukemia lymphoma, one is to code the primary site to the site of origin when lymph node(s) or lymph node region(s), tissue(s) or organs are involved. The Note 4 instruction states it is necessary to go to Module 7 (Rules PH18-PH27) to code the more specific primary site. In this case, use Rule PH22 to code primary site to C779 [lymph nodes, NOS] for the case you describe.
In this case, there is involvement of abdominal lymph nodes, spleen, bone marrow and bone. There is no indication of the primary site. Per the Heme DB, the most frequent sites of involvement for the lymphoma are bone and lymph nodes. This is a Stage IV lymphoma.
The now inactivated SINQ 20120047, stated that based on the sites of involvement, this histology could be coded as either leukemia or lymphoma. If the only involvement is the bone marrow, the site is coded to C421 [bone marrow]. The involvement of peripheral blood does not change the primary site because such involvement is part of the leukemic process.
