20190094 | Reportability/Heme & Lymphoid Neoplasms--Skin: Is elephantiasis nostras verrucosa (ENV) reportable as a lymphoma? See Discussion. |
The autopsy report indicated a diagnosis of: Skin: Hyperkeratosis and pseudoepitheliomatous hyperplasia as well as reactive angioendotheliomatosis indicating Elephantiasis Nostras Verrucosa. |
Elephantiasis nostras verrucosa (ENV) is not reportable. ENV is a rare form of chronic lymphedema caused by any number of conditions including neoplasms, trauma, radiation treatment, congestive heart failure, obesity, hypothyroidism, chronic venous stasis, and parasitic infection. |

20190014 | Reportability--Behavior: Is reportable if it shows invasion or microinvasion pathologically? See Discussion. |
The SEER Manual states, Generally, this rule is invoking the Matrix principle in the ICD-O-3. We are aware this is not the same as a VIN III or an adenoma with microinvasion because those tumors have a valid histology code listed in the ICD-O-3. The terms or or do not have a valid ICD-O-3 code to apply the Matrix principle. If severe dysplasia is felt to be consistent with a carcinoma in situ, then a severe dysplasia with microinvasion would be reportable as 8010/3. But in the U.S., we do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |
Severe dysplasia alone is not reportable. No further instructions apply because this term is not reportable.In order to use the instructions for behavior, you must first have a reportable neoplasm. If carcinoma in situ is mentioned and there is microinvasion, code the behavior as /3 according to the instructions in the SEER manual. You are correct, do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |

20190010 | Reportability/Histology--Bladder: Is papillary urothelial neoplasm of low malignant potential (PUNLMP) (8130/1) reportable when also referred to as papillary transitional cell carcinoma, grade 1, no invasion (8130/2) previously? See Discussion. |
The pathology report reads: Urinary bladder, tumor over right ureteral orifice, biopsy: Urinary bladder mucosa (urothelium) and submucosa (lamina propria), with papillary urothelial neoplasm of low malignant potential (previously known as papillary transitional cell carcinoma, grade 1 of 3), no invasion identified. |
This case is not reportable. PUNLMP (8130/1) is the diagnosis stated by the pathologist for this case and PUNLMP is not reportable. The information in parentheses is informational in this case and does not change the pathologist's diagnosis. According to WHO Classification of Tumors of the Urinary System and Male Genital Organs, 4th edition, there is variation of architectural and cytological features between PUNLMP and papillary urothelial carcinoma, low grade, reflecting grading changes from an older classification system. |

20190032 | Summary Stage 2018--Lung: Are ground-glass lung nodules coded as distant for Summary Stage? See Discussion. |
Chest x-ray: Multifocal pneumonia in left lung; possibility of masses in left lung not excluded. Chest CT: 4 large ground-glass masses in LUL (largest 46mm); beginning of Tree-In-Bud appearance in LUL; 2 small ground-glass nodules in right lung. Lung LUL biopsy: Adenocarcinoma, Solid Predominant. No further information as patient did not want to discuss treatment options. Per the AJCC book and CAnswer Forum, multifocal classification should be applied equally whether the lesions are in the same lobe OR in different ipsilateral lobes OR contralateral lobes, cT2b(m), cN0, cM0. |
Do not assume that ground glass presentation is consistent with a neoplasm. There are numerous causes of a ground glass lung condition such as sarcoidosis or pulmonary fibrosis. A ground glass lung opacity may also be observed in conditions such as alveolar proteinosis, desquamative pneumonitis, hypersensitive pneumonitis, and drug-induced or radiation-induced lung disease. If an area of ground glass opacity persists in the lung, it is usually classified as an adenocarcinoma, a classification that ranges from premalignant lesions to invasive disease. This is in line with AJCC that states to stage based on the largest tumor determined to be positive for cancer. To Summary Stage the case example provided, ignore the lesions in the contralateral lung (do not assume that they are malignant). There are multiple lesions in the left lung, but once again, do not assume that those not biopsied are malignant. This leaves us with the lesion confirmed to be malignant, making this a Localized (code 1) tumor. |

20190017 | Reportability--Heme & Lymphoid Neoplasms: The term indolent systemic mastocytosis is listed in the 2018 ICD-O-3 Histology Update table with borderline behavior (9741/1). However, smoldering systemic mastocytosis is listed in the Hematopoietic and Lymphoid Database (Heme DB) as an alternate name for histology 9741/3. Are smoldering systemic mastocytosis and indolent systemic mastocytosis synonymous? If so, should smoldering systemic mastocytosis also be removed from the Heme DB alternate names listing? See Discussion. |
In addition to the issue mentioned above, there is a SINQ answer that conflicts with the 2018 ICD-O-3 Histology Update table. SINQ 20130134 indicates indolent systemic mastocytosis is reportable for cases diagnosed 2010 and forward. There is no date restriction indicating the SINQ note applies only for cases diagnosed 2010-2017. Since indolent systemic mastocytosis was changed to borderline (9741/1) for diagnosis year 2018+, should the diagnosis year range be updated for this SINQ answer? |
Smoldering systemic mastocytosis is reportable, 9741/3. Indolent systemic mastocytosis is not reportable as of cases diagnosed 2018, 9741/1. Smoldering systemic mastocytosis and indolent systemic mastocytosis are not synonymous. Smoldering differs from indolent based on diagnostic criteria and burden of disease; indolent is low whereas smoldering is high burden of disease that can progress to aggressive systemic mastocytosis or mast cell leukemia. We will update SINQ 20130134. |

20190066 | Solid Tumor Rules (2018)/Histology--Breast: How is the histology coded for a metastatic carcinoma, consistent with primary breast carcinoma, when no other pathology information is available? See Discussion. |
The 2018 Breast Solid Tumor Rules Equivalent Terms and Definitions - Changes from 2007 Multiple Primaries/Histology Rules states: Mammary carcinoma is a synonym for carcinoma no special type (NST)/duct carcinoma not otherwise specified (NOS) 8500. It will no longer be coded as carcinoma NOS 8010. Should metastatic carcinomas of breast origin be 8500, or is code 8010 (carcinoma NOS) more applicable because histology coding from metastatic sites is not as reliable? |
Code as 8500/3 as it is the only tissue available for this carcinoma associated with a breast primary. Breast carcinoma NST/NOS is now coded as 8500. |

20190104 | Histology--Corpus uteri: Is 8020/3 used for a predominantly dedifferentiated carcinoma with focal well-differentiated endometrioid adenocarcinoma diagnosed in 2018? See Discussion. |
After a little research, it appears as though Endometrial Dedifferentiated carcinoma is a relatively new term and is set to be included in ICD-O-3.2: http://www.iacr.com.fr/index.php?option=com_content&view=category&layout=blog&id=100&Itemid=577 If you look at the link on that page for All Additions, Changes, and Revisions to the ICD-O-3, 1st Revision for ICDO-3.2, there is 8020/3 Dedifferentiated carcinoma. Currently, 8020/3 is Carcinoma, undifferentiated, NOS. For 2018 diagnosis, would you use 8020/3 for a predominantly dedifferentiated carcinoma with focal well-differentiated endometrioid adenocarcinoma as stated in the pathology: Uterus, bilateral ovaries and fallopian tubes; supracervical hysterectomy/BSO: Predominantly dedifferentiated carcinoma with focal well-differentiated endometrioid adenocarcinoma in the endometrium, FIGO grade 1 Portion of omentum, omental/anterior abdominal wall/ round ligament/uterine/small bowel mesenteric tumor nodules all involved by dedifferentiated carcinoma. Synoptic reads as follows: Histological Type: Endometrioid carcinoma, NOS Dedifferentiated carcinoma predominantly Histological Grade: Endometrioid carcinoma, FIGO grade 1. |
Assign code 8380/3 for endometrioid carcinoma, NOS as this is listed as the histological type in the synoptic report. |

20190081 | Race: How is race coded for a patient who self-reports as white? In the Family History portion of the genetics consult, it states the maternal family is of mixed European and Cherokee descent; the paternal side is of mixed German/mixed European descent. Is race coded as Race 1: 03-American Indian and Race 2: 01-White, or as 01-White according to self-report by the patient? |
Self-reported information is the highest priority for coding race. That is because the race information for the U.S. population comes from census data and that information is self-reported. For national cancer statistics, in order for the numerator (cancer cases) and the denominator (population) to be comparable, use self-reported race information whenever it is available. We will add this clarification to the SEER manual. |

20190086 | EOD 2018/Primary tumor--Melanoma: The code and level translations in the Note 4 of Extent of Disease (EOD) Primary Tumor for Melanoma Skin seem incorrect. Please advise. * Code 000: In situ * Code 100: Level I (should be level II) (< 0.75 mm Breslow's Depth) * Code 200: Level II (should be level III) (0.76 mm to 1.50 mm Breslow's Depth) * Code 300: Level III (should be level IV) (> 1.50 mm Breslow's Depth) |
Please see the corrected levels below for the note. Note 4: If a Breslow's depth is given in the pathology report and there is no other indication of involvement, the following guidelines may be used (Note: If a physician documents a different Clark's Level than provided by these guidelines, go with the physician's Clark Level) Code 000: Level I (In situ) Code 100: Level II (< 0.75 mm Breslow's Depth) Code 200: Level III (0.76 mm to 1.50 mm Breslow's Depth) Code 300: Level IV (> 1.50 mm Breslow's Depth) Thank you for bringing this to our attention. |

20190075 | Sex: How should the sex field be coded for the newly allowable non-binary gender designation ? See Discussion. |
Washington State added to birth certificates, which allows people to have their certificates changed to this non-binary gender designation. Gender X is defined as a gender that is not exclusively male or female, including, but not limited to: intersex, agender, amalgagender, androgynous, bigender, demigender, female-to-male, genderfluid, genderqueer, male-to-female, neutrois, nonbinary, pangender, third sex, transgender, transsexual, Two Spirit, and unspecified. |
Code Gender X as 9 when that is the only information available. Use text fields to document the details. Also refer to coding instruction #7. When gender is not known Assign code 1 when the primary site is C600 'C639 Assign code 2 when the primary site is C510 'C589 Assign code 9 for primary sites not included above |
