20190007 | Reportability--Skin: Is atypical intradermal smooth muscle neoplasm (AISMN) of the skin reportable? The comment on the path report states: Atypical intradermal smooth muscle neoplasm (AISMN) was previously termed "cutaneous leiomyosarcoma." |
Atypical intradermal smooth muscle neoplasm (AISMN), previously termed "cutaneous leiomyosarcoma," is not reportable. It is classified as a borderline, /1, neoplasm. |

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. |

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. |

20190082 | Primary site/Histology--Peritoneum: What is the correct primary site code for peritoneal mesothelioma in a female? When I use C482, it seems that the fields are all geared towards primary peritoneal carcinoma with FIGO staging, etc. |
For mesothelioma, NOS (9050) and epithelioid mesothelioma (9052) of the peritoneum for females, assign C481, C482, or C488 as appropriate based on the site of origin in the medical documentation. The Primary Peritoneal Ca schema is assigned and you will need to complete the SSDIs for FIGO staging, CA-125 PreTx Interpretation, and Residual Tumor Volume Post Cytoreduction. If the histology is 9051 or 9053 with primary site of C481, C482, or C488 for females, the Retroperitoneum schema is assigned. The only SSDI for this schema is Bone Invasion. |

20190058 | Solid Tumor Rules (2018)/Histology--Cervix Uteri: What is the histology code and what H Rule applies for a diagnosis of papillary squamotransitional cell carcinoma of the cervix? See Discussion. |
It appears that the first Other Sites applicable rule is H16 (and Table 2) instructing the use of histology code 8323 (mixed cell adenocarcinoma). However, this really is not an adenocarcinoma tumor but is a mixed squamous and transitional cell carcinoma. The 2018 ICD-O-3 Histology Update Table provides a new term for a but does not indicate whether that new term would also include a papillary squamotransitional cell carcinoma of the cervix. |
Code papillary squamotransitional cell carcinoma (PSCC) as 8120/3 using the 2018 Other Sites Solid Tumor Rules, Rule H11. PSCC is a distinctive subcategory of squamous cell carcinoma of the uterine cervix. WHO Classification of Tumors of Female Reproductive Organs say that squamotransitional cell tumors show papillary architecture with fibrovascular cores lines by multilayered atypical epithelium. |

20180111 | Reportability/Histology--Appendix: Is high grade appendiceal mucinous neoplasm (HAMN) diagnosed in 2018 reportable? See Discussion. |
Example: Initial CT scan impression is large appendiceal mucocele with a moderate amount of right-sided abdominal ascites. Faint mural enhancement suggesting an underlying appendiceal neoplasm (mucinous adenoma or adenocarcinoma). Appendectomy follows two days later with final diagnosis of high-grade appendiceal mucinous neoplasm, see comment. Histologic grade: Grade G2 of 4 (based on the CAP protocol) . . . Ascites fluid (ThinPrep(r) and cell block preparations): Mucin, fragments of debris, and macrophages. No diagnostic neoplastic cells are identified . . . Pathologic stage: pT4a, pNX, pM1a (AJCC 8th ed). Diagnosis Comment states, We feel that there are areas of this tumor where the cytologic atypia is beyond what one would expect in low-grade appendiceal mucinous neoplasm. While mitotic figures are not strikingly increased, there are focal nuclear changes that would support classification of this tumor as high-grade appendiceal mucinous neoplasm. Approximately two weeks later the patient has an Oncology assessment stating new diagnosis of T4a, NX, M1a, Stage IVA high-grade mucinous adenocarcinoma of the appendix with mucinous ascites. Patient has had an appendectomy but no further surgery so far. However, anecdotally, the best reported case series has been with surgical debulking followed by HIPEC chemotherapy In that instance I have recommended surgery with intraperitoneal chemotherapy. Is this a reportable malignancy? If so, what is the best histology for the diagnosis? |
2022 and later HAMN is reportable. Assign 8480/2. |

20180019 | Marital Status: Is Marital Status always a self-reported status? See Discussion. |
The SEER Manual states that Marriage is self-reported for the instruction in code 2, but it does not indicate if all other marital statuses are self-reported. Examples: How is Marital Status reported for the following situations? 1. Patient with multiple tumors in the database, for the first tumor marital status is reported as married (code 2), for the subsequent tumor, marital status is reported as single (code 1). 2. Patient self- reports as single, but also has children. 3. Patient states they are in common law marriage, but our state is not a common law marriage state. |
Marital Status is self-reported because the information is recorded in the medical record based on information obtained from the patient. Use text fields to document relevant information. Examples 1. Assign code 2 for the first tumor and assign code 1 for the subsequent tumor unless the available information indicates the patient is divorced at the time of the subsequent tumor diagnosis. Patient may self-report single after a divorce. Assign code 4 in that situation. The code assigned for marital status reflects the patient's marital status at the time of diagnosis for the tumor being abstracted. It is possible that marital status may be different for each tumor if the patient has multiple tumors. 2. If marital status is stated to be single, assign code 1. 3. If marital status is stated to be common law marriage, assign code 2. Common Law Marriage is defined as a couple living together for a period of time and declaring themselves as married to friends, family, and the community, having never gone through a formal ceremony or obtained a marriage license. |

20180054 | Solid Tumor Rules (2018)/Histology--Bladder: Under the Terms that are Not Equivalent or Equal section (Urinary Equivalent Terms and Definitions) it indicates noninvasive is not equivalent to papillary urothelial carcinoma and one should code the histology documented by the pathologist. However, many pathologists use Ta as both the description of the stage and the histology. Should this note be amended? See Discussion. |
The note in the Urinary Terms and Definition states, Both Ta and Tis tumors are technically noninvasive. Code the histology specified by the pathologist. While it is true that both Ta and Tis are technically noninvasive, the AJCC defines Ta specifically for, A pathologist's use of Ta does indicate the noninvasive carcinoma did arise from a papillary tumor. However, not all pathologists use terminology that, following the Urinary Solid Tumor Histology Coding Rules, will result in a histology coded to 8130, despite an AJCC-defined Ta (noninvasive papillary carcinoma) tumor having been diagnosed because the tumor projected from the wall on a stalk. In our region a number of pathologists provide the following types of diagnosis. Histologic type: Noninvasive. Histologic grade (WHO/ISUP 2016): High-grade. Tumor configuration: Papillary. The pathologist and/or physician may then stage this as Ta. How is the histology coded for these cases if the H Rules do not allow one to code the papillary and noninvasive Ta disease as not equivalent to noninvasive papillary carcinoma? Flat (in situ) urothelial carcinoma has an increased risk of invasive disease compared to the noninvasive papillary urothelial carcinomas. Will there be inconsistencies or a resulting impact to analysis of truly flat/in situ urothelial carcinoma vs. papillary urothelial carcinomas if the papillary tumors are not being coded as such? |
Per the April 2019 update: Noninvasive; papillary urothelial carcinoma; flat urothelial carcinoma Note: Noninvasive is not equivalent to either papillary urothelial or flat urothelial carcinoma. Both Ta and Tis tumors are technically noninvasive. Code the histology specified by the pathologist. |

20180034 | Reportability--Vulva: Is a biopsy showing high grade squamous intraepithelial lesion (VIN II) in the vulva reportable for cases diagnosed in 2018? See Discussion. |
In comparison to SINQ 20180022, this case does not mention VIN III anywhere in the final diagnosis. Is any mention of HGSIL in the final diagnosis reportable, even if it is qualified with a non-reportable term in parenthesis or CAP protocol? |
Since this HSIL diagnosis is specified as VIN II, do not report it. WHO includes both VIN II and VIN III as synonyms for HSIL of the vulva. HSIL is reportable and VIN III is reportable. VIN II is not reportable. |

20180103 | Histology/Grade--Small intestine: For a 2017 diagnosis, is the grade/differentiation field coded 1 or 9 when the diagnosis is well-differentiated neuroendocrine tumor (NET) (carcinoid)? It seems as though the term well-differentiated defines type of neuroendocrine tumor so they can diagnosis the carcinoid. See Discussion. |
5/15/17 Duodenal bulb, biopsy: Fragments of duodenal mucosa with well differentiated neuroendocrine tumor (carcinoid), extending to the edge of specimen and peptic duodenitis in the submitted tissue. No significant intraepithelial lymphocytosis. |
Assign grade code 1 for well-differentiated NET (8240/3). Well-differentiated is synonymous with NET, grade 1, according to WHO Classification of Tumors of the Digestive System. |
