20170063 | Reportability/Behavior--Ovary: Is adult granulosa cell tumor a reportable malignant tumor if the primary ovarian tumor ruptured intraoperatively, the peritoneum was contaminated, and the patient underwent adjuvant treatment with chemotherapy given the increased risk of recurrence due to intraoperative tumor spill? See Discussion. |
Per SINQ 20130176 and 20140034, adult granulosa cell tumors of the ovary are reportable malignant tumors when there are peritoneal implants or metastases. The SINQ responses describe how these adult granulosa cell tumors are different from low malignant potential (LMP) epithelial ovarian tumors. Would these SINQ scenarios apply to a case with intraoperative tumor rupture that resulted in peritoneal tumor? In this case, the pathologist indicated these excised peritoneal specimens were favored to be intraoperative contamination with adult granulosa cell tumor. However, the oncologist went on to treat this patient as high risk with chemotherapy. The oncologist only described one of the pelvic peritoneal implants as possibly contamination due to the rupture. The oncologist never indicated the tumors were definitely peritoneal implants. Should the behavior of this tumor be /1 because the peritoneal tumor appears to be contamination, or /3 because the oncologist treated this patient as high risk? |
If the "implants" were due to intraoperative contamination and were not present prior to surgery, do not interpret them as indicative of malignancy. The behavior of this tumor is /1. |

20170049 | MP/H Rules/Histology--Pancreas: What is the histology code of invasive adenocarcinoma, non-mucinous with intraductal tubulopapillary features, moderately differentiated, from the pathology report final diagnosis of the pancreas? Does 'intraductal" refer to a non-invasive/in-situ component or describe the pattern of growth? |
Assign 8503/3, intraductal papillary adenocarcinoma with invasion, to capture the more specific features of the adenocarcinoma. Histology Rule H13 for Other Sites states to code the most specific histologic term. Examples include Adenocarcinoma and a more specific adenocarcinoma. Note: The specific histology may be identified as type, subtype, predominantly, with features of, major, or with ___ differentiation. |

20170004 | MP/H Ruels/Histology--Kidney/renal pelvis: How is MiT family translocation renal cell carcinoma (RCC) with Xp11 translocation coded? See Discussion. |
Pathology states: Translocation renal cell carcinoma. Comment Tumor morphology and IHC profile consistent with MiT family translocation RCC with Xp11 translocation. |
Assign 8312/3 to MiT family translocation renal cell carcinoma (RCC) with Xp11 translocation. The recent WHO 4th Ed Tumors of the Urinary System has proposed a new ICD-O-3 code for MiT family translocation RCC, however the implementation of this new code has not yet been approved by the standard setters (SEER, CoC, CDC, NAACCR). Until it is approved, code histology to renal cell carcinoma (8312/3). |

20170062 | Race, ethnicity: How do you code race for someone from New Zealand? |
I recently did a presentation on coding the data item Race. In my presentation I discussed understanding geography help code race in some circumstances. One of the slides demonstrates how large Polynesia is and what Pacific islands are found in Polynesia, such as, Tahiti, Samoa, and even Hawaii, all of which have their own codes. Someone in the audience asked "How do you code New Zealand? Upon some research, New Zealand is not listed in Appendix D of the SEER coding manual. We could code them 01-White. But research shows there is a very large indigenous population. Technically, New Zealand is located within the boundaries of Polynesia - Code 25 (Polynesian). |
If the only information you have on race is that the person is from New Zealand, code race as white. This is based on the instructions for Australia, the closest neighbor to New Zealand as no other guidance was found. |

20170022 | MP/H Rules/Histology--Brain and CNS: What is the code for an embryonal tumor with multilayered rosettes. WHO shows the code as 9478/3, but this code is not available for use in the United States. |
Assign ICD-O-3 code 9392/3 until code 9478/3 is implemented in 2018. Per our expert neuropathologist, embryonal tumor with multilayered rosettes was previously called ependymoblastoma. |

20180062 | Histology--Heme & Lymphoid Neoplasms: How is histology coded when a lymph node excisional biopsy shows Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL), predominantly in diffuse T-cell histiocyte rich large B-cell lymphoma-like (THRLBCL) pattern. Comment states: The findings are that of nodular lymphocyte predominant Hodgkin lymphoma with diffuse T-cell rich pattern (T-cell/histiocyte-rich large B-cell lymphoma-like). This variant is regarded as clinically more advanced. See Discussion. |
It appears an argument could be made for both NLPHL (9659/3) and THRLBCL (9688/3). We favor coding NLPHL (9659/3) because the pathologist did specifically call this a Hodgkin lymphoma, and also specified that it only has a T-cell/histiocyte-rich large B-cell lymphoma-like pattern. |
Assign histology code 9659/3. According to the Hematopoietic database, this histology frequently has T-cells. The other description was not an actual histology, but noting that the appearance of the cells was similar to that histology. |

20180089 | Reportability--Appendix: Is disseminated peritoneal adenomucinosis (DPAM) reportable when it is being referred to as if the primary tumor is a low-grade appendiceal mucinous neoplasm (LAMN)? See Discussion. |
Example 1: 8/23/2017 debulking path diagnosis of low-grade appendiceal mucinous neoplasm (LAMN) with involvement of intrapelvic mucin, left ovarian mass, uterine serosa and pelvic tumor, consistent with disseminated peritoneal adenomucinosis, that may also be called low-grade mucinous carcinoma peritonei. 8/8/2018 resection of sigmoid and rectum, path diagnosis of peri-colorectal fibroadipose issue with low-grade mucinous carcinoma compatible with the prior diagnosis of pseumomyxoma peritonei with low-grade mucinous carcinoma histology. Example 2: Path diagnosis of low-grade appendiceal mucinous neoplasm in association with low grade mucinous carcinoma peritonei involving the serosa of the small intestine and mesentery. Also, there is involvement of serosal lined soft tissue of peritoneum, omentum, stomach, falciform ligament, gallbladder, diaphragm and spleen. Some pathologists in our area are referring to DPAM as mucinous carcinoma peritonei, which is causing confusion because the term carcinoma is being used. One would assume that because the pseudomyxoma peritonei/underlying tumor itself is low-grade (LAMN), then the case is not reportable, but we would like clarification. |
For cases diagnosed prior to 1/1/2022 Disseminated peritoneal adenomucinosis (DPAM) is not reportable when the primary tumor is a low-grade appendiceal mucinous neoplasm (LAMN). The term disseminated peritoneal adenomucinosis (DPAM) is discouraged by the WHO Digestive System monograph (page 123, section on pseudomyxoma peritonei (mucinous carcinoma peritonei)), since it does not clarify whether the process is low grade or high grade carcinoma. When used, the term should be referring back to the histology of the defining process and in both of these examples this appears to be LAMN, and therefore not reportable. The only exception to this might be if the peritoneal implants were invasive; that is, they contained adenocarcinoma invading into the underlying peritoneum, bowel serosa, etc., rather than simply being present within the surface mucinous material. The pathologist would make this clear if this was, in fact, believed to be invasive carcinoma. |

20180105 | 2018 Solid Tumor Rules/Histology--Lung: What is the appropriate histology code for the case below in the Discussion section? Is there a difference between adenocarcinoma in situ (bronchioloalveolar carcinoma), non-mucinous type (8252/2) and adenocarcinoma in-situ, mucinous? See Discussion. |
Procedure: Wedge, resection specimen, Laterality: Right, Tumor site: Right upper lobe, Tumor size: 1.0 cm in greatest dimension, Histologic type: Adenocarcinoma in-situ, mucinous, Histologic grade: N/A, Visceral pleura invasion: Not identified, Tumor extension: N/A, Margins: Uninvolved, Lymphocytosis. |
Assign 8253/2 for adenocarcinoma in situ, mucinous. New codes were added in 2018 for mucinous adenocarcinoma in situ for lung cancer only as all cases were not invasive. Pathologist are discouraged from using the term BAC. In-situ lung tumors can now be identified as either mucinous or non-mucinous and the appropriate ICD-O code should be assigned based on diagnosis. |

20180083 | Solid Tumor Rules (2018)/Multiple primaries--Bladder: How many primaries are abstracted and which M Rule applies when a patient is diagnosed with an invasive urothelial carcinoma tumor of the bladder, followed less than three years later by an invasive urothelial carcinoma and small cell neuroendocrine carcinoma tumor of the bladder? See Discussion. |
The Solid Tumor Rules indicate bladder tumors that are urothelial carcinoma (8120) and small cell carcinoma (8041) are separate primaries per Rule M13 (Abstract multiple primaries when separate/non-contiguous tumors are on different rows in Table 2). These are distinctly different histologies and, presumably, one would want to capture the small cell carcinoma (or small cell carcinoma component) as this has a worse prognosis. However, if a subsequent bladder tumor is composed of invasive urothelial carcinoma and small cell neuroendocrine carcinoma, the histology is coded as 8045/3 per Rule H4, but this is not abstracted as a multiple primary. The only M Rule that applies is Rule M18 (Abstract a single primary when tumors do not meet any of the above criteria). The mixed histology code 8045 is not included in Table 2, so none of the histology-based M Rules apply. Is the subsequent mixed invasive urothelial and small cell carcinoma tumor (8045/3) the same primary as a previously diagnosed invasive urothelial carcinoma (8120/3) when these tumors are diagnosed within three years? |
Abstract two separate primaries using Solid Tumor Rules Urinary Sites Rule M13. While not stated in the urinary sites rules, these are separate histology codes in two different rows in Table 2 of the Rules. The initial histology is 8120 and the subsequent tumor is 8045 using Rule H4. Adding 8045 to Table 2 will cause issues. Small cell neuroendocrine in the bladder is very rare, extremely aggressive, and usually has a component of urothelial carcinoma. |

20180003 | Histology/Diagnostic confirmation--Heme & Lymphoid Neoplams: Would you code the NOS term when follicular lymphoma is favored? What would diagnostic confirmation be coded if a positive fine needle aspirate (FNA) is followed by a positive flow cytometry (ambiguous term)? See Discussion. |
Pathology reads: 1. FNA left groin lymph node tissue (smears and cell block): B-cell lymphoma, low grade. The concurrent flow cytometry (3-FC-16-288) identifies a monoclonal B cell population with immunophenotype of CD10++, CD5-, CD23-, CD20++ and unusual CD19-. Overall findings favor follicular lymphoma. FNA Specimen Adequacy: Evaluation for specimen adequacy: Immediate cytology smear review for specimen adequacy was performed at the time of the FNA procedure by pathologist. Smears reviewed from 2 passes in one reading. The specimen was adequate cytological evaluation. Surg Path Final Report Special Studies Immunohistochemistry (CD45, MCK, CD20, CD3, CD10, Bcl6, MUM1 \T\ Ki67) was performed on block 1A to confirm the diagnosis. All controls show appropriate reaction. Lymphoma cells are positive for CD45, CD20, CD10 and weakly positive for bcl6(+) and MUM1(+/-), and negative for MCK. CD3 highlights few T lymphocytes. Ki67 labeling index is low, less than 10%. The immunoprofile supports above diagnosis. Chromosomal study for t(14;18) translocation will be performed, and an addendum report will follow. Flow Final Report Comment: The lymphoma appears to be derived from germinal centre B cells. Together with the findings from the lymph node biopsy (3-FN16-416), follicular lymphoma is favored. However, negative CD19 and CD22 are unusual. |
Code histology as follicular lymphoma, NOS (9690/3). The clinician rendered the diagnosis after review of all information available, including histology, cytology, and immunophenotyping markers. Assign diagnostic confirmation code 1 based on histology. Diagnostic confirmation code 3 cannot be assigned in this case because the diagnosis included ambiguous terminology and the immunophenotyping is not unique to follicular lymphoma, NOS. |
