20010044 | Reportability/Ambiguous Terminology/Date of Diagnosis: If a "suspicious" cytology is reportable only when a later positive biopsy or a physician's clinical impression of cancer supports the cytology findings, is the Date of Diagnosis field coded to the later confirmation date rather than to the date of the suspicious cytology? Is a suspicious "biopsy" handled the same way? |
Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed. Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy. Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not. |

20200066 | Reportability--Skin: Effective 2021, a cutaneous leiomyosarcoma is a related term for smooth muscle tumor, NOS (8897/1) in ICD-O-3.2. Currently, we have been capturing these as a C44_ (leiomyosarcoma, 8890/3) but the 2019 SEER inquiry states that atypical intradermal smooth muscle neoplasm (AISMN) was previously termed cutaneous leiomyosarcoma. This is not documented on the 2018 ICD-O-3 updates. Should this 2019 case be 8897/1 or 8890/3? |
Cutaneous leiomyosarcoma is reportable for 2019. Code histology to leiomyosarcoma 8890/3. As of cases diagnosed 1/1/2021, it is no longer reportable based on assignment to 8897/1 in ICD-O-3.2. |

20200009 | First course treatment/Surgery of Primary Site--Corpus uteri: Is an omentectomy performed with a hysterectomy for an endometrial primary site recorded under Surgery of Other Site? See Discussion. |
Per SEER 20140003, an omentectomy is not recorded under Surgery of Other Site when performed with a hysterectomy for an endometrial primary. Is this still correct? CoC appears to have different guidelines stating in a forum that an omentectomy is coded in data item Surgical Procedure to Other Site. I would like to confirm SEER guidelines. Is this one of those unique situations that SEER and STORE differ? Our state follows SEER guidelines and would like to communicate the appropriate rules to our facilities. |
Continue to record an omentectomy performed with a hysterectomy under Surgery of Primary Site and not as a separate procedure under Surgical Procedure of Other Site. The guidance In SINQ 2014003 and 20091118 is unchanged. |

20200087 | Solid Tumor Rules (2018)/Histology--Thyroid: What is the correct histology code for a micropapillary thyroid carcinoma for cases diagnosed 1/1/2021 and later? See Discussion. |
The 2021 ICD-O-3.2 Update includes papillary microcarcinoma (8341/3) as the preferred term for thyroid primaries (C739). However, there are multiple SINQ entries instructing registrars not to use code 8341/3 for diagnoses of micropapillary carcinoma of the thyroid (including SINQ 20071076, 20081127, 20110027, 20150023, and 20180008). SINQ 20150023 specifically indicates: Per the WHO Tumors of Endocrine Organs, for thyroid primaries/cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult (1 cm or less in diameter) and was found incidentally. WHO does not recognize the code 8341 and classifies papillary microcarcinoma of the thyroid as a variant of papillary thyroid carcinoma and codes histology to 8260. If the primary is thyroid and the pathology states papillary microcarcinoma or micropapillary carcinoma, code 8260 is correct. Does this clarification apply to cases diagnosed 2021 and later? If WHO feels the term micropapillary still does not refer to a specific histologic type for the thyroid, why is 8341/3 listed as a preferred term for this morphology/site combination? For cases 2021 and later, should a diagnosis of Incidental papillary thyroid microcarcinoma (3 mm) in left lower pole, be coded as 8341/3 per the ICD-O-3.2, or as 8260/3 per clarification in multiple SINQ entries? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
Continue to code micropapillary thyroid carcinoma to 8260/3 until instructed otherwise. This coding instruction is based on input from expert endocrine pathologists. This issue will be revisted based on the 4th Ed WHO Endocrine Tumors and updated if needed. |

20061136 | Primary Site: What site code best reflects the final diagnosis of a metastatic "pancreatobiliary" adenocarcinoma to the liver? See Discussion. |
CT showed multiple masses in the liver and lymphadenopathy in areas of gastrohepatic ligament, celiac axis, superior mesenteric and left periaortic regions. No mention of a mass in pancreas or common duct. When the term "pancreatobiliary" primary is stated in the final diagnosis, what site code should be used? |
Contact the physician for clarification of the term "pancreatobiliary." If no further information can be obtained for this case, assign code C249 [Biliary tract, NOS] based on the CT findings for the specific case in this question. When the primary is described as "pancreatobiliary" with NO FURTHER INFORMATION, assign C269. |

20240079 | Reportability/Histology--Conjunctiva: Is low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL) with focal high-grade features of the conjunctiva (C690) reportable? If reportable, what histology should be assigned? |
Additional comments in this pathology report state "The entire case was sent in consultation to an ophthalmic pathologist. [Pathologist] assigns a conjunctival melanocytic intraepithelial neoplasia (C-MIN) score of 2-3 due to the upward pagetoid migration of small, dendritic melanocytes. A C-MIN score of 2-3 is between low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL; C-MIN 2) and high-grade conjunctival intraepithelial lesion (HG-CMIL; C-MIN 3). The older terminology for this lesion would be primary acquired melanosis (PAM) with mild to focally moderate atypia." This term does not appear in the SEER Program Coding and Staging Manual (SPCSM), Appendix E1 of the SPCSM, or Solid Tumor Rules (specifically rule H3) . |
Conjunctival melanocytic intraepithelial neoplasia (C-MIN) is reportable; therefore, low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL) with focal high-grade features of the conjunctiva (C690) is reportable, 8720/2. We will add this to a future edition of the SEER manual. |

20160047 | Reportability--Eye: Is conjunctival intraepithelial neoplasia (CIN III) from an excision of the left eye conjunctiva reportable? |
Conjuctival intraepithelial neoplasia grade III (CIN III) is reportable. Intraepithelial neoplasia, grade III, is listed in ICD-O-3 as /2. It is reportable for sites other than skin. |

20061051 | Reportability--Melanoma: Is the final diagnosis for an excisional skin biopsy of "compound nevus with severe cytoarchitectural atypia and regression" reportable if a re-excision may be clinically indicated because there is an "overlap of morphology between malignant melanoma and nevi with severe atypia, and there's evidence of regression"? |
Compound nevus with severe atypia is not reportable unless also stated to be malignant melanoma or melanoma in situ. |

20160018 | Reportability--Brain and CNS: Is a colloid cyst at the foramen of Monro reportable? |
Colloid cyst at the foramen of Monro is not reportable. Colloid cysts are endodermal congenital malformations and do not have an ICD-O-3 code. See the Glossary for Registrars, http://seer.cancer.gov/seertools/glossary/view/542eeea1102c1d14697ef8ab/?q=colloid |

20210009 | Solid Tumor Rules (2018, 2021)/Histology--Melanoma: In what situation will Rule H4 be used to code the histology to regressing melanoma? See Discussion. |
Rule H4 states: Code 8723/3 (malignant melanoma, regressing) when the diagnosis is regressing melanoma. However, if the diagnosis was strictly regressing melanoma or malignant melanoma, regressing, the first rule that applies is Rule H1 because regressing melanoma is a single, specific histologic type and Rule H1 states: Code the histology when only one histologic type is identified. Following the current rules, one would never arrive at Rule H4. Should the H Rules be reordered? Or should an example of when one would use Rule H4 be added to clarify when to use this rule? |
Coding regressing melanoma has been an issue as registrars may not realize it is a reportable histology. Hence, H4 was written to reinforce correct histology. A note will be added to H1 instructing registrars to continue thru rules when the diagnosis is regressing melanoma. |
