20130010 | MP/H Rules/Histology--Skin: How is the histology coded for "infiltrative carcinoma with ductal alterations compatible with squamoid eccrine ductal carcinoma" of the skin? | Code the histology to 8413/3 [eccrine adenocarcinoma]. This is the most specific code available for this diagnosis.
According to our expert pathologist advisor, "The adnexal glands in the skin, sweat (eccrine) glands and apocrine glands, all have ducts which connect the business portion of each gland to the skin surface. Some of the adnexal tumors have features of differentiation which appear to be duct-like, hence the designation 'ductal.'"
In addition, "The 'squamoid' simply indicates some degree of squamous differentiation, but doesn't alter the usefulness of [code 8413/3] because we have no way of coding anything more specific in this case anyway." |

20150039 | Reportability--Skin: Is this reportable? If so, what is the correct histology code? The pathology report says, " bx of 0.7 x 0.5 cm gray-pink papule on tan-pink skin of left inferior centra malar cheek revealed invasive SCC of skin, signet ring cell type, invading papillary dermis; LVI neg; "findings are diag of SCC exhibiting the rare signet ring histologic subtype"; deep margin positive for tumor but peripheral margins clear;". |
SCC of skin, signet ring cell type, is not reportable to SEER. SCC's of skin classifiable to 8050-8084 are not reportable to SEER. See page 11 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf
Signet ring is a rare histological variant of SCC and is coded to 8070/3 according to the WHO classification for skin tumors. |

20200066 | Reportability--Skin: Effective 2021, a cutaneous leiomyosarcoma is a related term for smooth muscle tumor, NOS (8897/1) in ICD-O-3.2. Currently, we have been capturing these as a C44_ (leiomyosarcoma, 8890/3) but the 2019 SEER inquiry states that atypical intradermal smooth muscle neoplasm (AISMN) was previously termed cutaneous leiomyosarcoma. This is not documented on the 2018 ICD-O-3 updates. Should this 2019 case be 8897/1 or 8890/3? |
Cutaneous leiomyosarcoma is reportable for 2019. Code histology to leiomyosarcoma 8890/3. As of cases diagnosed 1/1/2021, it is no longer reportable based on assignment to 8897/1 in ICD-O-3.2. |

20091013 | Reportability--Skin: Is a "basal cell carcinoma of the skin of the lip with focal skin appendage differentiation" reportable? |
The histology code for basal cell carcinoma with skin appendage differentiation is 8098/3. Basal cell carcinomas (8090-8110) are not reportable to SEER. Skin appendage tumors are not reportable to SEER unless stated to be carcinoma or stated to be malignant. According to our pathologist consultant, basal cell carcinoma with focal skin appendage differentiation is basal cell carcinoma which exhibits adnexal (appendage) features, but it is still basal cell carcinoma. The case example above is not reportable to SEER. |

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. |

20000842 | Surgery of Primary Site--Skin: Explain the difference between code 30 and code 45.
Code 30 [Biopsy of primary tumor followed by a gross excision of the lesion]
Code 45 [Wide excision or re-excision of lesion or minor (local) amputation with margins more than 1 cm, NOS. Margins MUST be microscopically negative.] |
For cases diagnosed 1/1/2003 and after: Code 30 represents a biopsy or excision in which the margins of excision are less than 1 cm or the margins are unknown. Code 45 represents a wide excision in which it is known that the margins of excision are greater than 1 cm. | Skin | Surgery of Primary Site | 2000 | |

20180100 | Reportability/Primary Site--Skin: Is vulvar intraepithelial neoplasia III (VIN III) or associated invasive squamous cell carcinoma reportable when stated to be of the or or ? See Discussion. |
Example: Operative report states, partial simple vulvectomy, anoscopy with normal-appearing clitoris, clitoral prepuce, bilateral labia majora, and labia minora. There is a 1.5 x 1 cm raised, hyperpigmented lesion which appears consistent with VIN 3 on the perineal body, just to the right of midline, and not touching the midline. It goes quite close to the anus but is not touching the anus. Final diagnosis on resection is, Invasive squamous cell carcinoma arising in a background of high-grade squamous intraepithelial neoplasia (VIN III) with the following features: Location: perineum. Focal invasion arising in setting of 1 cm area of VIN III. |
Squamous carcinoma and squamous intraepithelial neoplasia III arising in the skin of the perineum (C445) are not reportable. Even though the abreviation "VIN III" is used in this example, this lesion does not involve the vulva. Since it involves the perineum, and skin of perineum is coded to C445, it is not reportable. Neoplasms arising in skin (C44) with the following histologies are not reportable. --Malignant neoplasm (8000-8005) --Epithelial carcinoma (8010-8046) --Papillary and squamous cell carcinoma (8050-8084) --Squamous intraepithelial neoplasia III (8077) arising in perianal skin (C445) --Basal cell carcinoma (8090-8110) |

20230074 | Extent of Disease/EOD Regional Nodes--Small Intestine: For an ileal/jejunal neuroendocrine primary, how should mesenteric soft tissue deposits (less than 2 cm) be collected in Extent of Disease (EOD) Staging? See Discussion. |
Example: Patient is diagnosed with grade 1 well-differentiated neuroendocrine tumor of the ileum, confirmed on ileocolic resection in 2023. The final diagnosis is a 2.8 cm ileal mass, with focal lymph-vascular invasion and a single 0.6 cm tumor deposit within mesenteric fat; primary tumor completely resected with widely negative margins and 10 regional nodes negative for malignancy. According to AJCC, mesenteric masses less than 2 cm should be stated in the pathology report as being present and collected by registrars but do not affect stage. EOD Regional Nodes has a code for large mesenteric masses greater than 2 cm only. How should we record these smaller tumor deposits if they are not supposed to affect stage? |
Do not code 500 for involvement of the mesentery unless the mesentery is specifically stated to be involved (and we don't have that information). We need more information on this case to assign EOD primary tumor. EOD Regional Nodes would be 000 per AJCC. |

20240033 | Solid Tumor Rules/Multiple Primaries--Stomach: Is a carcinoid tumor of the stomach diagnosed on 01/01/2023, on a patient who was followed up by Gastrointestinal (GI) and was found to have another stomach carcinoid on 02/01/2024, one primary or two? See Discussion. |
Based on the Solid Tumor Rules, we would make this two since it is over one year. According to a previous SINQ question 20110046, we are to code this as one primary. We see patients come back with multiple carcinoid tumors over the years and would like clarification. |
Stop at the first rule that applies which is M12. Per note 3: When it is unknown/not documented whether the patient had a recurrence, use date of diagnosis to compute the time interval. This means there are two primaries. There is a genetic syndrome that causes multiple carcinoid tumors in the GI tract, per our GI expert, and they should be treated as new primaries per M12. SINQ 20110046 describes a unique situation whereby the subject matter expert felt that the occurrence of multiple tumors was due to an unknown underlying condition driving the proliferation of neuroendocrine cells. |
