20140049 | Reportability--Brain and CNS: Is Tuberculum sellae meningioma reportable? Is it same as sphenoidale meningioma? Path: Brain tuberculum tumor resection: Meningioma, WHO grade I. |
Revised answer based on ST rules Yes, a Tuberculum sella meningioma is reportable if diagnosed 2004 or later. Code the primary site C700, cerebral meninges. It is a meningioma originating from the meninges of the Tuberculum sellae, which is part of the sphenoid bone. |

20140048 | MP/H Rules/Histology--Sarcoma: Is 8811/3 the correct code for myxofibrosarcoma (myxoid malignant fibrous histiocytoma) high-grade (grade 3/3)? |
8811/3 is the correct code for myxofibrosarcoma. See Rule J on page 33 in ICD-O-3. Fibromyxosarcoma is equivalent to myxofibrosarcoma. |

20140047 | MP/H/Multiple primaries--Urinary: In Aug 2008 Patient was diagnosed with Noninvasive Bladder Cancer. In Oct 2013 Patient was diagnosed with Transitional Cell Carcinoma of Right Ureter involving lamina propria, Noninvasive Transitional Cell Carcinoma Left Ureter and Invasive Transitional Cell Carcinoma of Prostatic Urethra. Is this a new primary and what is the primary site? |
Rule M7 applies when comparing the 2008 diagnosis to the 2013 diagnosis: multiple primaries.
Rule M8 applies to the tumors identified in 2013: single primary.
Based on the information provided, code the primary site for 2013 to C689 because there is no indication of the site of origin among the involved sites. |

20140046 | MP/H/Multiple Primaries--Urinary: Is this one primary with a C689 primary code and morphology 8130/3? Or is this 2 primaries: 1. C679 8130/3 and 2.C680 8120/2. See discussion. |
Urinary: Transitional Cell Carcinoma and open prostatectomy: Path from Bladder: Papillary and solid transitional cell carcinoma of bladder - grade II and III Stage A.
Path from prostatectomy: The prostatic tissue samples shows areas of urothelia carcinoma in situ - related to the tumor present in the bladder.
Conclusion: Prostatectomy showing foci of transitional cell carcinoma in situ of prostatic urethra. |
Abstract a single primary, C679 8130/3. Rules M2 and H4 apply. Transitional cell/urothelial carcinoma in the prostatic urethra is likely an extension from the known bladder TCC in this case, not a separate primary. See prostatic urethra on page 63 in the Urinary Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf |

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." |

20140039 | Reportability--Heme & Lymphoid Neoplasms: Is a statement of "JAK-2 positive polycythemia" reportable? See discussion. |
Polycythemia, NOS is not reportable. However, there is a statement in the Heme Manual Glossary for JAK2 that states, "When JAK2 is positive, the MPN is definitely reportable." Does a positive JAK 2 always mean there is a reportable myeloproliferative disorder or must there also be an associated statement of a reportable neoplasm (e.g., myeloproliferative disorder, polycythemia vera, or essential thrombocythemia)? |
A positive JAK 2 does not always mean there is a reportable myeloproliferative disorder. There must also be an associated statement of a reportable neoplasm (e.g., myeloproliferative disorder, polycythemia vera, or essential thrombocythemia). The glossary entry will be clarified. |

20140038 | MP/H Rules/Multiple Primaries--Urinary: How many primaries are there and which MP rules apply in this scenario? See discussion. |
Patient has 2 tumors in the left ureter; one is transitional cell (8120) and one is papillary transitional cell (8130). Rule M6 says BLADDER tumors with any combination of the following histologies ... are a single primary. But this is not a bladder case. Rule M8 says urothelial tumors in 2 or more of the following sites are a single primary... but this is not in 2 or more sites. Rule M9 then says histologies different at the 1st, 2nd, or 3rd digit are separate primaries. That makes this 2 primaries, but I do not think this should be 2 primaries. |
Rule M9 applies. Abstract 2 primaries.
We will evaluate this scenario for the next version of the multiple primary rules. |

20140036 | MP/H Rules/Multiple primaries--Prostate: Is duct carcinoma of the prostate the same as an adeno/acinar carcinoma of the prostate? Specifically, does rule M3 apply when there is an adenocarcinoma of the prostate followed by a duct carcinoma of the prostate or a duct carcinoma followed by adenocarcinoma? |
Rule M3 does not apply to adenocarcinoma followed by duct carcinoma of the prostate or vice versa. Rule M3 pertains to cases of adenocarcinoma and acinar carcinoma. These two terms, adenocarcinoma and acinar carcinoma, are equivalent for the purpose of applying the MP/H rules to prostate cases. See page 77 of the Other Sites Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf

20140035 | Reportability/MP/H Rules/Histology: Is this kidney tumor diagnosis reportable? If so, what is the correct histology? See discussion. |
Left radical nephrectomy: Tumor histologic type: Renal angiomyoadenomatous tumor (see Note). Note: The a clear cell papillary renal cell tumor and a renal angiomyoadenomatous tumor (""RAT"") (reval cell carcinoma with angioleiomyoma-like stroma). Although some authors consider RAT tumors to represent a pattern of clear cell papillary RCC we believe that this represents a dstinct entity. The combined findings ...confirm the diagnosis of renal angiomyoadenomatous (RAT) tumor. These tumors are also known as renal cell carcinoma within angioleiomyoma-like stroma. To date none of these tumors have developed metastases. Given the small number of reported cases we would consider these to have at worst a low malignant potential. |
According to our expert pathologist adviser, renal angiomyoadenomatous tumor ("RAT") is not reportable. He states "l would be reluctant to consider the entity malignant. The authors of the papers describing it do not seem ready to call it malignant either. I agree with calling it LMP, or in this case uncertain malignant potential." |

20140034 | Reportability--Ovary: Can you clarify when widely metastatic borderline histologies of the ovary and various other sites are reportable? See discussion. |
SINQ 20130176 states that an adult granulosa cell tumor of the ovary with metastases is malignant. However, SINQ 20091087 states that a borderline tumor of the appendix with metastasis is not reportable.
The first statement of 20130176 “though granulosa cell tumor is coded 8620/1, the presence of peritoneal or lymph node metastases indicate the tumor is malignant and coded as /3” does not coincide with the second statement of “the behavior of borderline/LMP ovarian epithelial tumors is determined by the ovarian primary, even though there may be peritoneal implants or metastatic disease in the lymph nodes”. If the ovarian metastases do make this a reportable malignancy, can this line of thinking be used to determine reportability for borderline histologies for other sites such as the appendix? |
The case in 20130176 is adult granulosa cell tumor. The answer points out an important difference in the way "metastases" from this histology should be interpreted versus low malignant potential ovarian epithelial tumors. Metastases from adult granulosa cell tumor of the ovary indicates a malignant primary. So-called metastases from a LMP epithelial tumor do not indicate a malignant primary when the metastatic deposits are also LMP/borderline in behavior.
Do not apply instructions for ovarian cases to other primary sites including appendix. |
