20230053 | Reportability/Histology--Ovary/Testis: Is serous borderline tumor-micropapillary variant (8460/2) of the ovary or testis reportable? If so, what dates are applicable to the reportability changes? See Discussion. |
Serous borderline tumor–micropapillary variant (8460/2, C569) was included in the ICD-O-3 Behavior Code/term updates effective 1/1/2018 but marked as Not Reportable for 2018. There have been multiple additional updates to the ICD-O but no further clarification as to the reportability of this histology. ICD-O-3.2 currently lists serous borderline tumor, micropapillary variant (C569) as 8460/2 with no mention of reportability and no information provided in Includes/Excludes. SINQ 20220032 instructs capturing this histology as reportable when diagnosed 1/1/2021 or later and occurring in the testis. The answer indicates this is reportable due to the /2 behavior code in ICD-O-3.2, but it does not specify that it is limited to specific sites. Is serous borderline tumor, micropapillary variant reportable for ovary? If so, what dates apply? Is serous borderline tumor, micropapillary variant of the testis diagnosed after 1/1/2021 reportable? |
Do not report serous borderline tumor–micropapillary variant of the ovary (8460/2, C569) as borderline ovarian tumors are not reportable. This applies to cases 2018 and later. Do report serous borderline tumor–micropapillary variant of the testis as stated in SINQ 20220032. It is reportable for cases diagnosed Jan 1, 2021 and later. |

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." |

20150003 | Reportability/Behavior: Is the following reportable, and if so, what is the histology code? Final Diagnosis (on multiple conjunctive excisions): Conjunctiva - primary acquired melanosis with atypia (see note). Note: "In all 3 specimens the process extends to the margins of excision. Complete extirpation is recommended (primary acquired melanosis with atypia is considered melanoma in situ). |
Do not report primary acquired melanosis with atypia.
According to our expert pathologist consultant, "There has been a lot of debate in the literature about the diagnostic criteria, terminology, and natural history of primary acquired melanosis [PAM]. Your case comes down squarely on the main issue, which is whether PAM with atypia should be regarded as melanoma in situ. In most studies it appears that PAMs with no atypia or mild atypia do not progress to melanoma, and only a small percentage of those with severe atypia do so." "PAM, even with atypia, is not melanoma in situ, and should not be reported."

20240031 | Reportability/Histology: Is a diagnosis of non-lung neuroendocrine tumorlet reportable? See Discussion. |
Patient was diagnosed March 2023 with a neuroendocrine tumorlet of the rectum measuring 0.8 mm via excisional biopsy during colonoscopy. Prior SINQ 20160011 (stomach specific) indicates microcarcinoid and carcinoid tumors are reportable. Microcarcinoid is a designation for neuroendocrine tumors of the stomach when they are less than 0.5 cm. in size. Is the current rectal tumor a reportable gastrointestinal neuroendocrine tumor if it is less than 5 mm (i.e., is a neuroendocrine tumorlet equivalent to a microcarcinoid)? |
Do not report neuroendocrine tumorlet of lung and non-lung sites. Microcarcinoid and carcinoid tumors are reportable. Tumorlet is a tumor of neuroendocrine differentiation, defined by size < 5 mm in diameter, mitotic count < 2 mitoses/2 mm², and absence of necrosis. Microcarcinoid is a designation for neuroendocrine tumors when they are less than 0.5 cm. in size. The term "tumorlet" is used in a number of other settings, referring to small tumors (usually < 0.5 cm), and does not necessarily mean carcinoid tumor. The term microcarcinoid tumor is not equivalent to neuroendocrine tumorlet. |

20180014 | Reportability/Histology--Brain and CNS: Is multinodular and vacuolating neuronal tumor of the cerebrum reportable, and if so, is the histology coded as 9492/0? See Discussion. |
Patient diagnosed with multinodular and vacuolating neuronal tumor of the cerebrum. My research shows: Multinodular and vacuolating neuronal tumor of the cerebrum is a recently reported benign, mixed glial neuronal lesion that is included in the 2016 updated World Health Organization classification of brain neoplasms as a unique cytoarchitectural pattern of gangliocytoma. There is no code in ICD-O-3 for it, so do I report it and use 9492/0 or not ? |
Do not report multinodular and vacuolating neuronal tumor of the cerebrum. At this time, WHO is undecided about whether this is a neoplastic or a hamartomatous/malformative process. If WHO makes a determination that this is a neoplastic process, we will update reportability instructions and ICD-O-3 guidelines for registrars. |

20240034 | SEER Manual/Reportability--Skin: Is keratoacanthoma (8071/3) of the skin reportable? This code is also for squamous cell carcinoma (SCC), keratinizing. In the 2024 SEER manual, 8071/3 falls under the not reportable section of skin (outside of specific sites). |
Do not report keratoacanthoma of the skin (8071/3). The preferred term for keratoacanthoma is squamous cell carcinoma (SCC), keratinizing, NOS. According to the 2024 SEER Manual, Reportability section, SCC of skin (8050-8084) is not reportable. |

20100013 | Reportability--Lymphoma: Should a December 2008 diagnosis of in situ follicular lymphoma be accessioned? See Discussion. |
Patient with mesenteric lymphadenopathy had a biopsy. Consult supports original pathology findings: The histologic and immunophenotypic findings represent what has been referred to in the literature as "in situ follicular lymphoma." The oncology assessment states, "At this point the patient has no other obvious evidence of other disease. ...no hepatosplenomegaly...no peripheral adenopathy...no significant abnormalities on PET scan to suggest active lymphoma." No treatment is planned at this time. The patient will only be monitored. |
Do not report in situ lymphoma at this time. Currently, lymphoma cannot be reported with a behavior code of in situ (/2) and it would be incorrect to abstract in situ lymphoma as a /3.
It is true that this is a recently identified pathologic entity. Our experts say that there is still some controversy to be ironed out regarding the criteria for identifying an in situ lymphoma. Their recommendation was to wait until clear guidelines had been established for the pathologists before we start collection of in situ lymphomas. We anticipate collecting these entities in the future. |

20180040 | Reportability--Kidney: Is congenital cellular mesoblastic nephroma reportable for a newborn baby? See discussion. |
2015 Rt kidney nephrectomy pathology states: congenital cellular mesoblastic nephroma, tumor sz 5.9cm, tumor limited to kidney, extension into pelvicalyceal system, margin not applicable, LVI negative. Per PubMed.gov: (In newborns) among the low-grade malignant tumors, congenital mesoblastic nephromas can be successfully treated with simple nephrectomy. Per ScienceDirect: ...currently thought that cellular mesoblastic nephroma is actually a renal variant of infantile fibrosarcoma. |
Do not report congenital mesoblastic nephroma (8960/1). Congenital mesoblastic mephromas are low-grade fibroblastic neoplasms of the infantile renal sinus according to WHO Classification of Tumors of the Urinary System and Male Genital Organs. The WHO classification is the standard used to determine behavior and histology for entities not listed in ICD-O-3. |

20230052 | Reportability/Primary Site--Brain and CNS: What is the primary site of a meningioma arising from the jugular bulb/petrous aspect of the temporal bone? See Discussion. |
Example July 2022, Brain CT describes a mass appearing to be centered on the petrous aspect of the temporal bone with intracranial and extracranial extension. July 2022, Brain MRI describes an extra-axial mass centered in the right jugular bulb with intracranial and intraosseous extension as well as extension within the internal jugular vein. September 2022, Resection operative report surgical findings are of a calcified mass filling middle ear, abutting stapes and appearing to enter the stapes obturator foramen, debulked. Final diagnosis is right middle ear meningioma, WHO grade I of III. Is this a reportable intraosseous meningioma of the temporal bone/skull base, or a non-reportable meningioma arising in a meningocele within the middle ear? |
Do not report cases of meningioma originating in the jugular bulb or petrous aspect of temporal bone or middle ear. These are not intracranial locations. This is a non-reportable meningioma arising in a meningocele within the middle ear. The jugular bulb is the confluence of the lateral venous sinuses situated in the jugular fossa. The precise location of this structure within the temporal bone is variable.The jugular bulb, petrous aspect of temporal bone, and middle ear are not intracranial locations, and therefore meningiomas arising in these areas are not reportable. |

20240024 | Reportability/Histology: Is angiomyxoma (this includes borderline or behavior code /1 cases) of the soft tissue reportable? Can you provide us with coding guidelines for angiomyxoma for when its reportable or not reportable? |
Do not report angiomyxoma. ICD-O-3.2 assigns 8841/0 to this benign tumor. This includes superficial and deep (aggressive) angiomyxoma. |
