20081122 | MP/H Rules/Histology--Breast: Patient has single invasive left breast tumor diagnosed in 2008. Final pathology diagnosis is "Invasive solid papillary carcinoma". No mention of ductal in report. What is histology? | For cases diagnosed 2007 or later: As of July 2010: Code the histology 8503 [Infiltrating papillary adenocarcinoma]. This is solid papillary, not solid AND papillary carcinoma. Solid is an adjective modifying papillary, in other words, a subtype of papillary. We do not have a code for solid papillary, so we code to the NOS, papillary using rule H14. |

20081113 | Reportability--Brain and CNS: Is a cavernoma reportable as a benign brain tumor? See Discussion. |
Cavernous hemangiomas are typically described as vascular malformations in the brain. Per a search of the literature, cavernoma, cavernous hemangioma and cavernous malformation are all synonymous. There is some controversy as to whether cavernomas are vascular malformations or tumors. Cavernous hemangioma (9121/0) has been assigned a code in the ICD-O-3. The other terms are not even listed. Benign brain guidelines indicate that named tumors that have been assigned an ICD-O-3 code are reportable. Would we report a lesion that is labeled cavernous hemangioma but not one that is labeled carvernoma? Are cavernous malformations of the brain to be reported as benign brain tumors? The MP/H guidelines for benign brain tumors do not include blood vessel tumors in chart 1. Are the following tumors reportable? If so, what is the primary site? Example 1: Patient admitted for resection. Clinical diagnosis is left temporal cavernous hemangioma. Path diagnosis is cerebral cortex and white matter showing cavernoma. Example 2: Patient admitted for resection with clinical diagnosis of parietal cavernous hemangioma. Path shows A-V malformation. Example 3: Patient had T4 spinal tumor removed. Path showed cavernous angioma. Reference: I&R 18109 and 23460 |
Cavernoma is a reportable benign brain tumor. According to our pathologist consultant, cavernoma is synonymous with cavernous hemangioma. Examples 1. Reportable. Primary site - C710 [cerebrum] 2. Not reportable. Path dx disproves clinical diagnosis. 3. Not reportable. Not a brain tumor. |

20081070 | CS Lymph Nodes/CS Mets at DX--Ovary: How are the following lymph node regions/chains coded in the Collaborative Stage schema for ovary?
1. pericolonic 2. pelvic, NOS 3. mesenteric, NOS |
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Revised 7-17-09 Assign CS Lymph Nodes code 10 for involvement of pelvic lymph nodes, NOS. Code involvement of pericolonic nodes or mesenteric nodes, NOS in CS lymph nodes. |

20081100 | MP/H Rules/Histology--Rectum: When not specifically mentioned as part of the histology, is the adenoma a second histologic type, or just a further physical description of the tumor? See Discussion. |
Rectal tumor resection (APR) path report final dx: "mucinous carcinoma, see comment". The comment is the CAP-format tumor summary, which states "histologic type: adenocarcinoma with extensive mucin production (mucinous or colloid carcinoma). Additional pathologic findings: adenomas - tumor arises in a tubulovillous adenoma". If you follow the rules and only use the final dx, you would code a different histology than if you use the 'additional path findings.' |
For cases diagnosed 2007 or later Other Sites histology rule H12 applies in this case. Assign histology code 8263 [adenocarcinoma in tubulovillous adenoma]. Use information from the CAP protocol and from comments associated with the final diagnosis to code histology. The fact that the malignancy arose in a polyp can be taken from anywhere in the medical record; not limited to the final diagnosis. Based on the information provided for this case, the histology is adenocarcinoma with extensive mucin production (mucinous or colloid carcinoma) arising in a tubulovillous adenoma. |

20081038 | Histology/Primary site: What is the correct histology code for sarcomatoid carcinoma of the mandible diagnosed in 2007? See Discussion. |
Left mandible resection: Malignant tumor, favor high grade sarcomatoid carcinoma. Please see comment. Comment: Considering the focal stain with P63 and the consult from Mayo Clinic done on the previous biopsy, the diagnosis of sarcomatoid carcinoma is more likely. Gross: left mandible resection...sectioning reveals a...mass that has replaced the majority of the mandibular bone and is at the medial, anterior lateral and posterior soft tissue margins and comes to within 2.4 cm of the anterior boney resection margin and 1.9 cm of the smooth articular temporal mandibular joint surface. The combination of C411 and 8033/3 is impossible (with no override available). |
Code the primary site C031 [Mandibular gingiva]. Code the histology 8033 [sarcomatoid carcinoma]. This tumor originated in the mandibular gingiva and invaded the bone (mandible) -- It did not originate in the bone. This type of tumor does not originate in bone. |

20081139 | Date Multiple Tumors--Prostate: For a prostate biopsy done 10/20/08, both lobes involved with tumor, unknown how many tumors, what would be coded in date of multiple tumors? | In this case, code the date of the biopsy in Date of Multiple Tumors [10202008]. When the number of tumors is unknown, code the date of diagnosis as the Date of Multiple Tumors. This is the date on which it was determined that there were an unknown number of tumors. This instruction will be added to next edition of the MP/H manual. | 2008 | |
|
20081021 | Primary Site/Surgery of Other Site--Leukemia: If hairy cell leukemia is diagnosed at splenectomy, and 1 month later a bone marrow confirms the same diagnosis, is the primary site coded to spleen or bone marrow? If the site is bone marrow, is the splenectomy coded to 2 (regional) or 4 (distant) in the surgery field? | For cases diagnosed prior to 1/1/2010:Primary site: Code the primary site to C421 [bone marrow] per primary site coding instructions for leukemia in the 2007 SEER manual, page 70.
Surgery of other site: Since all surgical procedures for hematopoietic diseases are coded in the data item Surgery of Other Site, assign code 1 [Nonprimary surgical procedure performed]. For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20081138 | MP/H Rules/Histology--Lung: What is the correct histology code for a neuroendocrine neoplasm described as a carcinoid and also referred to as oncocytic? See Discussion. | Left mainstem bronchus mass excised: metaplastic endobronchial mucosa with submucosa containing an infiltrating poorly diff malignant tumor. Origin of tumor is not identified in overlying mucosa. IHC stains will be performed. Addendum #1. IHC stains show well diff neuroendocrine neoplasm, favor carcinoid. Recommend sending this to expert in lung neoplastic pathologist. Addendum #2. (lung path specialist) oncocytic neuroendocrine neoplasm. Is this 8246 or 8290 or something else? |
For cases diagnosed 2007 or later, code as 8246 [Neuroendocrine carcinoma, NOS]. According to our pathologist consultant, the neuroendocrine description is more specific than the oncocytic description in this case. | 2008 |

20081119 | Reportability/Date of diagnosis--Liver: Does the final diagnosis of a scan have higher priority than the findings in the discussion in the body of the report? See Discussion. |
A patient with liver cancer becomes transplant eligible when the tumor is 2 cm in size. Frequently, liver tumors will be watched (no biopsy) for months until they meet the 2 cm size criteria. In the meantime, multiple scans will describe the tumor using variations of ambiguous terms that drift in and out of reportablility. One day the tumor is labeled "presumed hepatocellular carcinoma." Weeks later it is back to "worrisome for hepatoma." A single scan will use different terms in different sections of the report. Example case: Abdominal CT reveals a 1 cm liver lesion. Per the discussion portion of the scan, the lesion is consistent with hepatocellular carcinoma. Per final diagnosis: 1 cm liver lesion, possibly hepatocellular carcinoma. Is this report diagnostic of cancer? Would the date of this report be the date of diagnosis? (Patient did receive a liver transplant for hepatocellular carcinoma months later.) |
When a reportable ambiguous term is used in one part of a report or the medical record and a non-reportable ambiguous term is used in another part of the report or the medical record, accept the reportable term and accession the case. The example above is reportable. "Consistent with" is a reportable ambiguous term. Accept "consistent with" over the non-reportable term "possibly." The date of this report would be the date of diagnosis if this is the earliest report using reportable terminology. |

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. |
