20160068 | Reportability--Brain and CNS: Are sphenoid wing meningiomas reportable? See discussion. |
It's my understanding that true intraosseous meningiomas are very rare. It's also my understanding that cranial meninges DO cover the sphenoid wing, so I'm wondering if it's possible to have a meningioma of the sphenoid wing on imaging that arises from the meninges NOT the bone. Is that the deciding factor on reportability? It's been suggested to me that meninges cells do lie within the bone, but again if a meningioma is described as being located at the sphenoid wing on imaging, without bone involvement - and no surgery is performed - I do not understand why it is specifically excluded as non-reportable. |
This answer pertains to cases diagnosed prior to 2018. For 2018 and later cases, refer to the Non-Malignant CNS Solid Tumor Rules. Note: This answer updates previous answers which have been removed from the SEER Inquiry System. Intraosseous meningiomas are not reportable. You are correct, these are rare meningiomas originating in bone. The term "sphenoid wing meningioma" is sometimes used for an intraosseous meningioma of the sphenoid bone. Yes, it's possible to have a meningioma of the sphenoid wing on imaging that arises from the meninges NOT the bone. Read the available information carefully. When the site of origin is described as "along the sphenoid wing" or "overlying the sphenoid wing" report the meningioma. These descriptions indicate that the meningioma originates from the meninges covering bone rather than the bone itself. Meningioma arising in bone is rare enough, that when present, we would expect it to be clearly stated as such. In the absence of a statement indicating origin in bone, the meningioma is most likely arising from meninges covering the bone. |

20160030 | Reportability--Carcinoid: Is a diagnosis of carcinoid heart disease, based solely on clinical information and no pathology, reportable? |
Carcinoid heart disease is not reportable but this diagnosis indicates that the patient likely has a carcinoid tumor which may be reportable. Obtain further information. |

20160024 | Reportability--Melanoma: Please explain how a CTR is to interpret the guideline in the MP/H rules (Cutaneous Melanoma): Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. Is this to mean that evolving melanoma in situ is not reportable? Or should we follow the guidelines in SEER Question 20130022 that states the reportability terms for melanoma and melanoma in situ. |
Follow the guidelines in SINQ 20130022 for now. When the MP/H rules are revised, new instructions will be implemented.
See also SINQ 200120078 and 20110069. |

20160067 | MP/H Rules/Histology--Skin: What histology code and MP/H Rule apply to a skin primary with the final diagnosis, ? See Discussion. |
The patient had an upper arm shave biopsy with final diagnosis of basaloid carcinoma with squamous and neuroendocrine differentiation. The pathologist also comments: Further resection was negative for residual malignancy.
Would SINQ 20150033 apply, thus resulting in final histology of carcinoma with neuroendocrine carcinoma (8574/3)? |
Assign 8574/3 according to Other Sites rule H17 for basaloid carcinoma with squamous and neuroendocrine differentiation.
There is no combination code that includes basal cell, squamous, and neuroendocrine. We can combine basal cell with squamous, 8094/3, or carcinoma with neuoendocrine differentiation, 8574/3. Rule H17 directs us to assign the higher code, 8574/3. |

20160021 | Primary Site--Stomach: How do I code the primary site when the operative report and pathology report state that the tumor site is incisura of the stomach? |
Assign C163. Incisura, incisura angularis, gastric angular notch, angular incisure of stomach all refer to the sharp angular depression in the lesser curvature of the stomach at the junction of the body with the pyloric canal. See Gastric angular notch in #12 on page 76 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf. See also the SEER training website, #12 on the illustration corresponds to the angular notch, http://training.seer.cancer.gov/ugi/anatomy/stomach.html. We will correct the key for this illustration. |

20160005 | Reportability--Skin: Is this a reportable skin cancer? See discussion. |
Patient had a skin biopsy and this is the interpretation: NASAL SUPRATIP: INVASIVE BASAL CELL CARCINOMA OF SKIN WITH NEUROENDOCRINE DIFFERENTIATION
NOTE: The deep margin is positive for tumor; peripheral margins negative for tumor. The tumor has a basaloid appearance with focal areas appearing slightly squamoid, and it demonstrates myxoid/mucinous retraction from the stroma. It does not demonstrate peripheral palisading of cells within tumor nests and has nuclear chromatin which suggests neuroendocrine differentiation. Mitotic rate is more brisk than typical basal cell carcinoma as well. The differential diagnosis includes basal cell carcinoma with or without neuroendocrine differentiation, basal cell carcinoma with squamous differentiation, basaloid squamous cell carcinoma, Merkel cell carcinoma and metastatic small cell carcinoma. The tumor is further characterized per immunostains x 9 (controls work well). Tumor cells are positive for Ber EP4 and p63; focally positive for Chromagranin; while negative for EMA, CK20, CK7, TTF-1, CD56 and Synaptophysin. Overall, the staining pattern supports basal cell carcinoma with neuroendocrine differentiation. |
Basal cell carcinoma with neuroendocrine differentiation of the skin is not reportable to SEER.
In this case, the pathologist discussed several possible options, and determined that the final diagnosis is basal cell ca with neuroendocrine diff based at least partially on the immunostains. |

20160073 | MP/H Rules/Multiple primaries/Histology: What histology and how many primaries are coded for a mixed germ cell tumor with a somatic type malignancy (rhabdomysarcoma) if the patient was diagnosed with seminoma of the testis in 2009 followed by a 2015 metastatic germ cell tumor in a retroperitoneal lymph node, stated to be a recurrence of the testicular cancer? See Discussion. |
In September 2009 the patient was diagnosed with seminoma, classical type, following an orchiectomy. Testicular mass recurrence in 2014 was treated with chemotherapy. Then in April 2015 a retroperitoneal dissection of a peri-aortic LN was positive for mixed germ cell tumor with somatic type malignancy (rhabdomyosarcoma) involving 1/11 nodes. Path Comment: major component of tumor is teratoma, rhabdomyosarcoma represents <5% of mass. Now in October 2016, the patient has a retroperitoneal mass biopsy positive for spindle cell sarcoma with rhabdomyosarcomatous differentiation. The comment section of the pathology report states, "Given the history of a germ cell tumor w/ rhadbomosarcomatous component, the findings are consistent with a recurrence of rhabdomyosarcomatous component of germ cell tumor." Can a seminoma transform to a mixed germ cell tumor with a somatic type malignancy (see SINQ 20140082 - testicular teratoma with somatic type malignancy)? |
According to our expert pathologist consultant, yes, seminoma could transform to a mixed germ cell tumor with a somatic type malignancy. He advises us to code this case as 9061/3. From our expert pathologist consultant: This occurs as "reprogramming" of the initial germ cell tumor/seminoma cell. The process is not understood, but genetic studies support this progression concept. Most often the next step is teratoma. It is out of the teratoma that the somatic malignancy usually comes. I do wonder about the possibility that this was really an embryonal carcinoma which resembles a seminoma - occasionally this can be a difficult separation. I wonder if they radiated the scrotum following the orchiectomy, also, given the scrotal recurrence. |

20160046 | MP/H Rules/Multiple primaries--Bladder: How many primaries should be reported for the case below? See discussion. |
1993 Renal pelvis: Papillary urothelial carcinoma
1994 Bladder: Noninvasive bladder ca NOS
6/11/13 Bladder: Noninvasive papillary urothelial carcinoma
8/19/14 Bladder: urothelial carcinoma in situ
2/13/15 Bladder: Papillary urothelial carcinoma
Would this situation be 2 primaries - 1993 Renal pelvis and 1994 Bladder with the 2015 being the same primary as 1993 Renal pelvis? Or 3 primaries - 1993 Renal pelvis, 1994 Bladder, 2015 Bladder? |
Abstract four primaries, 1993 renal pelvis, 1994 bladder, 2013 bladder, and 2015 bladder.
The 1993 renal pelvis diagnosis and the 1994 bladder diagnosis are separate primaries based on the rules in effect at that time (See pages 7-11, http://seer.cancer.gov/archive/manuals/historic/codeman_1992.pdf )
For the remaining diagnoses, the 2007 MP/H rules apply. The 2013 bladder diagnosis is a new primary per rule M7. The 2014 bladder diagnosis is not a new primary per rule M6. The 2015 bladder diagnosis is a new primary per rule M5. |
