20071093 | Reportability--Brain and CNS: In addition to Schwannoma, are there additional types of benign tumors that arise in peripheral nerves along the spinal cord that are not reportable? See Discussion. | Are neuroepitheliomatous neoplasms such as ganglioneuroma, gangliocytoma, ganglioglioma occurring along the spinal cord reportable? Are nerve sheath tumors such as neuroma occurring along the spinal cord reportable? Angioma? Reference: SINQ 20051071; Primary Central Nervous System Tumors, NPCR Training Materials 2004 |
Reportability depends on the location of the tumor. Tumors in the following sites are reportable:
Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Please note: spinal schwannomas arising in the nerve root or spinal dura are reportable. |

20031171 | Reportability: Is pseudomyxoma peritonei always reportable? See Description. | In the ICD-O-3, pseudomyxoma peritonei has a behavior code of 6, indicating that it is malignant. Does this imply that pseudomyxoma peritonei is always a reportable malignancy? In the past, our pathologist consultant told us that pseudomyxoma peritonei is only a reportable malignancy if the underlying tumor is malignant. A benign cystadenoma of the appendix, for example, can rupture causing pseudomyxoma perionei. Does SEER agree with our pathologist consultant? Example: Patient was found to have psuedomyxoma peritonei. Right hemicolectomy was done. Path reported an appendix with mucinous cystic tumor of undetermined malignant potential. A definite diagnosis of cancer can not be rendered. |
Reportability is determined from the behavior of the primary tumor and the behavior of implants. If either are malignant, the case is reportable. The case example does not seem to be reportable, based on the available information. Cancer diagnosis has not been made according to the pathology report. |

20200041 | Reportability--Brain and CNS: Is an intradural T12/L1 capillary hemangioma reportable? See Discussion. |
Example: MRI found an intradural, extra-axial mass at T12/L1 with possible intramedullary component. Resection of the intradural intramedullary and extramedullary spinal cord tumor found a capillary hemangioma pathologically. The microscopic description on the path report describes a tumor with extensive vascularity involving the dura. Should we equate the statement of capillary to mean the tumor is arising in a blood vessel as we do for venous hemangioma (non-reportable per SINQ 20130001)? Or should it be reportable as C700, 9131/0 because it is described as involving the dura (intradural, intramedullary and extramedullary)? |
Reportability of capillary hemangioma depends on the site of origin. If it originates in the dura, it is reportable. If it originates in a blood vessel, it is not reportable. The site of origin is not clear in the information provided. Sites of involvement are mentioned, but not the site of origin. Capillary could refer to the site of origin or to the propensity of this tumor to form tiny blood vessels. If the site of origin cannot be confirmed as dura, do not report this neoplasm. |

20210070 | Histology/Reportability--Digestive System: Is “neuroendocrine neoplasm” reportable? See Discussion. |
We are confused by SINQs 20180097, 20150001, and 20140051. The latter two indicate that “well-differentiated neuroendocrine neoplasms” of the duodenum and appendix are reportable because they’re synonymous with neuroendocrine tumor (NET). Yet 20180097 states “primary hepatic neuroendocrine neoplasm” is NOT reportable unless there is documentation that it’s being used as a synonym for Primary Hepatic Neuroendocrine Tumor (PHNET). In addition, we see in the 2021 ICDO-3.2 update that only “poorly differentiated neuroendocrine neoplasm” is listed with behavior code /3 and noted to be reportable for 2021+ on the companion annotated histology list. Does reportability of neuroendocrine neoplasms depend on primary site, differentiation terminology within the histology name, or something else? Our casefinding staff is hoping for a general reportability guideline to follow when they come across “neuroendocrine neoplasms” NOS. For example, we have a 2020 pathology report for a core biopsy of a soft tissue pelvic mass with final diagnosis of low grade neuroendocrine neoplasm; there is no further clarification as to whether it is felt to be primary or metastatic, and we have no other associated records for this patient in our central registry. |
Reportability of neuroendocrine neoplasms depends on primary site, terminology, and differentiation. "Neuroendocrine neoplasm" is an umbrella term for a variety of neuroendocrine tumors and carcinomas. Neuroendocrine neoplasm, not otherwise specified (NEN, NOS) is not reportable as in your example unless it is being used as a synonym for neuroendocrine tumor (NET), as with digestive system tumors. According to WHO Classification of Digestive System Tumors, 5th ed., NENs of the appendix and liver are epithelial neoplasms with neuroendocrine differentiation, including well-differentiated tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). The guidance in SINQ 20180097, 20150001, and 20140051 is still valid. |

20071030 | Reporting Source: If the only patient record available for a physician office biopsy is the pathology report identified from a freestanding laboratory, is reporting source coded to 3 [Laboratory Only (hospital-affiliated or independent)] or 4 [Physicians office/Private Medical Practitioner (LMD)]? See Discussion. | A case was identified through a pathology report from a freestanding lab. The doctor who submitted the specimen left the state. His records cannot be located. Because the patient had the specimen removed at a physician's office, not at a path lab, is Type of Reporting Source field coded to the physicians office? | Reporting Source is the source that provided the best information used to abstract the case. For this case, assign code 3 [Laboratory Only (hospital-affiliated or independent)]. Reporting source should reflect the lab where this case was identified. The MD office added nothing to the case, not even a confirmation of malignancy. |

20190056 | Behavior--Breast: What is the behavior of a solid papillary carcinoma when a pathologist does not indicate it in the pathology report and follow-up with the pathologist to obtain clarification regarding the behavior is not possible? See Discussion. |
Example: Mastectomy specimen final diagnosis shows two foci of invasive ductal carcinoma including: Invasive ductal carcinoma, no special type, in association with solid papillary carcinoma (tumor #1, 1 cm, slices 6 and 7) and invasive ductal carcinoma, no special type (tumor #2, 1.2 cm, slices 9 and 10). Summary Staging outlines, Tumor #1: Histologic Type: Invasive ductal carcinoma, no special type, in association with solid papillary carcinoma. As well as, Tumor #2: Histologic type: Invasive ductal carcinoma, no special type. Additional findings include ductal carcinoma in situ (DCIS): presently approximately 3.3 cm, spanning slices 10-13. The behavior of the solid papillary carcinoma component will affect the provisional histology of the first tumor (8523/3) per Rule H17 vs. 8500/3 per Rule H7). Based on the response, we can determine whether this represents a single or multiple primaries (single primary per M13 vs. multiple primaries per M14). |
Review all sections of the pathology report carefully for any mention of invasion, or lack of invasion, pertaining to the solid papillary carcinoma. Per WHO 4th Ed Breast: If there is uncertainty that there is invasion, these lesions should be regarded as in situ. The distinction between in situ and invasive disease in solid papillary carcinoma is difficult. |

20200025 | Reportability/Ambiguous terminology--Bone: Is a case reportable when the imaging described a left first rib mass as ? See Discussion. |
The radiologist noted the mass was most compatible with a chondroid lesion, which is not reportable on its own, but can the subsequent term be used to accession this as reportable if only one malignant etiology is provided by the radiologist? Or does the statement imply that this is only one of several possible etiologies? |
Review this case with the involved physicians to determine their opinion on the bone mass. Review the plans for further evaluation and treatment (if any) to determine whether the physicians view this case as a chondroid lesion, chondrosarcoma, or something else. If it is not possible to obtain further information, do not report the case at this time. If further information becomes available, review the case again for reportability. |

20180101 | Histology--Kidney: What is the histology code for renal cell clear cell of the kidney with subsequent epithelioid angiomyolipoma PEComa of the liver stated to be metastatic? Case originaly diagnosed in 2016. See discussion. |
This patient was diagnosed in 2016 with renal cell clear cell and was coded to that. In 2018, the patient's liver lesion was resected and pathology revealed epithelioid angiomyolipoma perivascular epithelioid cell tumor (PEComa) (8714/3), a new term as of 2018. This was compared to the kidney slides and it was determined to be metastatic PEComa from the kidney. The physician's note states: The patient had a nephrectomy for a kidney tumor in 2016, excision of cutaneous melanomas, and resection of liver mass in 2018. These three cases were sent in consultation. The diagnosis of cutaneous melanoma was confirmed by a dermatopathologist of our department, (a separate report had been already issued). The kidney tumor is poorly differentiated composed of sheets of discohesive cells with markedly pleomorphic cells with frequent giant and bizarre cells. Most of the cells have abundant eosinophilic to clear cytoplasm. The nuclei are enlarged and pleomorphic. Multinucleated cells are numerous. Some cells have markedly enlarged nucleoli. Multifocal tumor necrosis is noted. Extensive lymphovascular invasion is observed. There are foci at the periphery of the tumor consisting of a proliferation of spindle cells with entrapped adipocytes consistent with minor element of unusual angiomyolipoma (see block A18). The liver tumor has histologic features that are similar to the poorly differentiated component of the kidney tumor. |
Revise the histology code for the 2016 diagnosis based on the review of slides performed in 2018. When new information becomes available, the information in the abstract can be updated. PEComa is a synonym for epithelioid angiomyolipoma (8860/1). These tumors can be malignant with local recurrence and or mets. For a pre-2018 diagnosis, code histology to 8860/3 using the ICD-O-3 Rule F, aka: Matrix principle. |

20150024 | Surgery of Primary Site--Breast: How should the Surgery of Primary Site field be coded when a patient has a lumpectomy and an additional margin excision during the same procedure? See discussion. |
Operative report indicates a wire localized lumpectomy was performed. The pathology report includes a final diagnosis for two specimens as follows: A) LEFT BREAST, EXCISION: INFILTRATING DUCTAL CARCINOMA B) LEFT BREAST, NEW DEEP MARGIN, EXCISION: BENIGN BREAST TISSUES AND BENIGN FIBROFATTY SOFT TISSUES; NO EVIDENCE OF NEOPLASIA. The definition for Breast surgery code 23 is "Reexcision of the biopsy site for gross or microscopic residual disease". There is no indication whether the re-excision has to be a separate procedure or can be during the same procedure as the excisional biopsy (lumpectomy). Some hospital registrars in our region believe code 22 is more appropriate. |
Revised Answer Assign code 22 when a patient has a lumpectomy and an additional margin excision during the same procedure. According to the CoC, "Re-excision of the margins intraoperatively during same surgical event does not require additional resources; it is still 22. Subsequent re-excision of lumpectomy margins during separate surgical event requires additional resources: anesthesia, op room, and surgical staff; it qualifies for code 23." |

20081059 | Reportability/Histology--Head and Neck: Is a right cerebellopontine (CP) angle endolymphatic sac papillary tumor (ELST) reportable? If so, what is the histology code? |
Revised December 2015
ELST is reportable. Code histology to adenocarcinoma (8140/3). Code primary site to inner ear (C301).
Endolymphatic sac tumors are rare non-metastasizing adenocarcinomas that originate in the endolymphatic sac of the inner ear (C301). They are slow growing and widely invade, and in later stages often destroy, the petrous bone. The WHO Classification assigns ICD-O-3 code 8140/3. |
