20031021 | Primary Site--Head & Neck: What is the anatomical distinction among tonsillar fossa, tonsillar pillar, and tonsil NOS? | Operative findings describe a right tonsil three times the size of the left tonsil. Tonsil is dissected from the tonsillar fossa. There appeared to be no involvement of tumor below the tonsillar capsule. | The tonsil lies in an indentation called the tonsillar fossa. The tonsillar fossa is bordered on either side by the tonsillar pillars. The tonsillar pillars are part of the supporting structure of the throat opening.
Code C09.9 [Tonsil NOS] as the primary site for the case above. |

20150025 | Primary Site--Lung: What are the guidelines for coding primary site when a lung tumor is described as a hilar mass? See discussion. |
At a recent meeting, one registry stated that they apply the following guidelines. 1) If the tumor is described as a hilar mass and there is no mention of LN involvement, Primary Site is coded to hilum (C340) 2) If there is LN involvement along with the mention of a hilar mass, then Primary Site is coded to C349 |
Assign primary site code C340 when a lung tumor is described as a hilar mass. |

20110104 | Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C421 [bone marrow] or C770-C779 [lymph nodes] for an adult T-cell leukemia/lymphoma [9827/3] that presented with a positive bone marrow biopsy and involvement of lymph nodes and the lung? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph..
Code the primary site to the involved lymph nodes [C770-C779]. Per Rule PH 8, it indicates you are 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. Note 2 further states that the bone marrow may or may not be involved. If the bone marrow is involved, code this information in the CS Extension field.
Per the Abstractor Notes section in the Heme DB, this is a systemic disease with widespread lymph node involvement as well as involvement of the peripheral blood. In addition, systemic involvement of extranodal sites (including lung) are often involved.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx. |

20100008 | Primary site--Bladder/Unknown & ill-defined sites: Should the coding of primary site be based on a molecular study when it is not verified by a clinical correlation? See Discussion. | Patient was seen in 2009 at Hospital A for bone pain and was found to have metastatic adenocarcinoma. A paraffin block specimen was sent to BioThernostics for THEROS CancerTYPE ID Molecular Cancer Classification Tests. The results came back with a 94% likelihood that the urinary bladder was the primary site. No scans were done on the abdomen or pelvis.
The patient was then sent to Hospital B for radiation to the bones and chemotherapy (Carboplatin and Taxol). The patient died within 6 months.
According to Hospital A, the primary site is bladder based on the molecular study report. Hospital B says this is an unknown primary. Which is correct? Do we take primary site from these tests, even when no clinical correlation is documented? |
Code primary site to bladder in this case. Code the known primary site when given the choice between a known primary site and an unknown primary site. | Bladder, Unknown & ill-defined sit | Primary site | 2010 |

20150035 | Primary site--Anus/Anal Canal: What site do you code squamous cell carcinoma of the anal verge? |
Assign C211 for anal verge. Anal verge is defined as the lower (distal) end of the anal canal, junction between the skin of the anal canal and the perianal skin, http://www.seer.cancer.gov/manuals/2015/AppendixC/rectosigmoid/coding_guidelines.pdf |

20130214 | Primary site--Heme & Lymphoid Neoplasms: Does Rule PH20 apply if a patient with lymphoma has bilateral axillary and bilateral inguinal lymph node involvement? | Rule PH20 states to code the primary site to the specific lymph node region when multiple lymph node chains within the same region as defined by ICD-O-3 are involved. Note 1 further states that one is to use this rule when there is bilateral involvement of lymph nodes. | Rule PH21 applies to this situation which states to code the primary site to multiple lymph node regions, NOS (C778) when multiple lymph node regions, as defined by ICD-O-3, are involved and it is not possible to identify the lymph node region where the lymphoma originated. Axillary nodes are coded to C773 and inguinal nodes are coded to C774. There are two lymph node regions involved. Code the primary site to C778 [multiple lymph nodes].
If this patient had only bilateral axillary OR only bilateral inguinal nodes are involved, then PH20 would have applied and you would code to the specific lymph node region mentioned. |

20150015 | Primary Site--Testis: What is the prmary site for a 38 y/o male diagnosed with testicular cancer in a formerly undescended testis that was treated with orchiopexy at age 10-11? See discussion. |
Should it be coded to where the testis was physically at the time of diagnosis (C621), or should it be coded to C620 to reflect the increased risk for developing malignancy in an undescended testis? |
Code the primary site C621 (descended testis). The primary site of this neoplasm is a scrotal (descended) testis. The history of orchiopexy can be noted in a text field, but does not change the primary site in this case. |

20140040 | Reportability/Primary Site--Lip: Is a right lower lip (NOS) squamous cell carcinoma reportable when the microscopic description states the tumor arises from the epidermis and extends through the dermis? See discussion. |
We are having difficulty determining whether the primary site is lip, NOS (C009) or skin of lip (C440). Usually we look for a statement of “skin” or “mucosa” in the microscopic description if the specimen label is only lip, NOS as instructed by the previous SINQ 20051049. Is a statement of "epidermis" or "dermis" in the microscopic description enough to indicate carcinoma is arising in the skin of the lip (C440) and thus not reportable? |
This case is interpreted as skin of lip and not reportable. According to our expert pathologist consultant, the pathologist in this case "is specifically saying "epidermis" and "dermis" and I would have to think it is skin, and thus not reportable." |

20200079 | Solid Tumor Rules (2018)/Primary Site--Brain and CNS: Should the updated note for optic nerve glioma be included in both the 2018 Solid Tumor Rules for Malignant Central Nervous System (CNS) and Peripheral Nerves, Note 6, and the Non-Malignant CNS Tumors, Note 5? See Discussion. |
Should the updated Note 5 from the Non-malignant CNS regarding optic nerve glioma also be incorporated into Note 6 for Malignant CNS rules (the pilocytic astrocytoma note)? This was one of the major issues identified in the SEER*Educate Workshop. Registrars have demonstrated they do not consistently think to look at the Non-malignant CNS schema when they see the term glioma and continue to misclassify optic nerve gliomas as malignant. This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The 2022 Solid Tumor Update will include a new note in the Terms & Definitions, Introduction section that will state: See the Non-malignant CNS rules when the primary site is optic nerve and the diagnosis is either optic glioma or pilocytic astrocytoma. The behavior is non-malignant and coded 9421/1. |

20041070 | Primary Site: What would the primary site be for carcinoma of the renal pelvis, status post transplant? Please see details below. See Discussion. | The patient has a renal pelvis urothelial carcinoma confined to the pelvis but is status post renal pelvic transplant of the same renal pelvis. | Code the primary site to renal pelvis [C659]. Code the site in which the primary tumor originated. The transplant status in this example does not affect the primary site. | N/A | Primary site | 2004 |
