20150054 | Primary Site--Skin: Should cutaneous leiomyosarcoma be coded to primary skin of site (C44_) or soft tissue (C49_)? |
Code cutanteous leiomyosarcoma to skin. Leiomyosarcoma can originate in the smooth muscle of the dermis. The WHO classification designates this as cutaneous leiomyosarcoma. The major portion of the tumor is in the dermis, although subcutaneous extension is present in some cases. |

20061053 | Diagnostic Confirmation: How is this field coded for a case with a cytology that is suspicious for ductal carcinoma and the clinical diagnosis is carcinoma? See Discussion. | SINQ 20031152 states that histology for this type of case is to be coded per the clinical diagnosis of "carcinoma." Does it follow then that Diagnostic Confirmation is to be coded 8 (clinical diagnosis only)? Would we code Diagnostic Confirmation differently if the clinician stated that the diagnosis of malignancy was confirmed by the suspicious cytology? | Code diagnostic confirmation as 8 [clincial diagnosis] when there is a suspicious cytology and a physician's clinical diagnosis. Do not accession cases with only suspicious cytology. Code diagnostic confirmation as 8 when the clinician's diagnosis of malignancy is confirmed by the suspicious cytology. It is still a clinical diagnosis made by the physician using the information available for the case. |

20160034 | First course treatment/Immunotherapy--Heme & Lymphoid Neoplasms: Is donor leukocyte infusion for treatment of hematopoietic neoplasms coded as a bone marrow transplant per the Hematopoetic Manual or as immunotherapy per SEER Inquiry System (SINQ) 20110048? See Discussion. |
In the Hematopoetic Manual, page 22, it is states: "The use of donor leukocyte infusions for treatment of hematopoietic neoplasms, specifically leukemias, is increasing. Abstract as bone marrow transplant when a reportable hematopoietic neoplasm is treated with donor leukocyte infusion, even if it is not listed in the treatment section of the Heme db for the specific neoplasm." Question 20110048 in the SEER Inquiry, it is stated "Donor lymphocyte infusion (DLI) is coded as immunotherapy." Donor lymphocyte infusion and donor leukocyte infusions are the same procedure. Please clarify discrepancy as coding is needed for a case treated with donor lymphocytic infusion. |
Code donor lymphocyte infusion as immunotherapy. SINQ 20110048 is correct. The Hematopoietic Manual will be corrected during the next update. |

20180018 | MP/H Rules/Histology--Brain and CNS: How should histology be coded for the following 2017 cases (pituitary adenoma vs. prolactinoma)? See Discussion. |
1. (2017) Pituitary mass resection with a path diagnosis of Do we code as prolactinoma when the tumor is immunoreactive for prolactin or must there be a definitive statement of ? 2. (2017) Pituitary lesion on imaging, MD diagnosis of Current (2007) MP/H rule H9 states when there are multiple histologies in the same branch in Chart 1, code the more specific histology. These histologies are NOT in Chart 1, but prolactinoma seems to be a more specific type of pituitary adenoma. The next rule, H10 states to code the numerically higher code, 8272/0 (pituitary adenoma)? 3. (2017) Imaging diagnosis of pituitary macroadenoma with clinical diagnosis by MD of macroprolactinoma. Current rules indicate when there is no path specimen that physician reference to type of tumor has priority over imaging. Will these answers/histologies change with the upcoming 2018 Solid Tumor rules? |
Code each of these 2017 cases as prolactinoma (8271/0), the more specific histology. If these cases were diagnosed in 2018, the answer would be the same: code as prolactinoma. |

20220016 | Histology--Thyroid: What is the correct histology code for a follicular carcinoma, minimally invasive, oncocytic variant of the thyroid? See Discussion. |
There is an ICD-O histology code for follicular carcinoma, minimally invasive (8335/3) as well as follicular carcinoma, oxyphilic cell (8290/3). Per SINQ 20150045, the term oncocytic is synonymous with oxyphilic in this context. The Multiple Primaries/Histology General Instructions and histology rules do not include the term “variant” as a term that can be used to code a further histologic subtype. The term “variant” can be used for the Other Sites (non-updated STR sites) when the ICD-O-3.2 (or ICD-O-3 for older cases) provides the term “variant” in the histology name. |
Code follicular carcinoma, minimally invasive, oncocytic variant of the thyroid to follicular carcinoma, oncocytic variant (8290/3). The term "variant" is commonly used in thyroid histologies and if appropriate, used to determine histology code. The WHO Classification of Tumors of Endocrine Organs, 4th edition, lists synonyms for 8290/3 as Hürthle cell carcinoma; oncoycytic carcinoma; oxyphilic carcinoma; follicular carcinoma, Hürthle cell type; and follicular carcinoma, oncocytic variant. |

20071066 | Grade, Differentiation--Bladder: Can grade be coded from the pathology report for a recurrent bladder cancer specimen? See Discussion. | In 2006 a TURB was done for bladder carcinoma diagnosed 10 years ago. Is grade always coded 9 on class 3 cases unless the original slides were reviewed? | Code grade from the original tumor; do not code grade from recurrence. If the grade of the original primary tumor is specified, code it, regardless of class of case. |

Solid Tumor Rules/Histology--Bladder: How is histology coded for a transurethral resection of the bladder (TURB) diagnosis with multiple components? See Discussion. |
Examples: Bladder TURB: Invasive high grade urothelial carcinoma with poorly differentiated (40%), lipoid (5%), and sarcomatoid (55%) components. Bladder tumor base TURB: Invasive high grade urothelial carcinoma with poorly differentiated (65%) and sarcomatoid (30%) components. The Urinary Sites Solid Tumor Rules, histology coding rules, say to code the most specific histology or subtype/variant, regardless of whether it is described as majority, minority, or component. Poorly differentiated (8020) and sarcomatoid (8122) are both urothelial subtypes, but there is no rule to instruct how to code a tumor/tumors with multiple urothelial subtypes. |
Code histology as 8120/3 in the two examples using Note 1 in the Urinary Sites Solid Tumor Rules, instruction 1 of the Coding Histology section. The subtypes/variants or components must describe a carcinoma or sarcoma in order to code a histology described by those terms. |

20170068 | MP/H Rules/Histology--Lung: What is the histology of a lung tumor described as solid predominant with mucin production, 8230/3 (Multiple Primaries/Histology (MP/H) Rule 5) or 8255/3 (MP/H Rule 6)? See Discussion. |
Pathology report: Left lower lobe lung, Tumor Size: Greatest dimension: 3.0 cm Additional dimensions: 2.5 x 2.0 cm; Tumor Focality: Unifocal; Histologic Type: Invasive adenocarcinoma Solid predominant with mucin production; Histologic Grade: G3: Poorly differentiated. Is the correct histology for this case 8230/3 (rule H5) or 8255/3 (rule H6)? |
Code histology as 8230/3, solid adenocarcinoma with mucin formation, using MP/H Rule H3 as one histologic type is identified. All of the histologic terms (solid, mucin production) are covered by 8230/3. Therefore, rule H3 applies. Use the first rule that applies, and stop. |

20230065 | Solid Tumor Rules/Histology--Prostate: Is histology coded as 8045 (Combined small cell carcinoma) for a 2023 diagnosis of two-component carcinoma comprised of both acinar adenocarcinoma and small cell neuroendocrine carcinoma of the prostate? See Discussion. |
This patient does not have a previous diagnosis of prostate adenocarcinoma nor a previous history of androgen-deprivation therapy. Does the logic in the Other Sites Solid Tumor Rules (STRs) noted in SINQ 20200052 still apply? This SINQ confirms a diagnosis of mixed prostatic adenocarcinoma and small cell neuroendocrine carcinoma is 8045. This matches the STRs instructions for Rule H21 and Table 2 (Mixed and Combination Codes), row 1. Row 1 indicates a mixed small cell carcinoma and adenocarcinoma is combined small cell carcinoma (8045). For a patient without previous treatment, is this the correct mixed histology code? |
Code histology as combined small cell carcinoma (8045) based on the Other Sites Solid Tumor Rules, May 2023 Update, Table 2, Mixed and Combination Codes, for this mixed histology prostate carcinoma consisting of adenocarcinoma and small cell neuroendocrine carcinoma regardless of treatment status. This is similar to SINQ 20200052 that applies to one tumor with mixed histologies. |

20180003 | Histology/Diagnostic confirmation--Heme & Lymphoid Neoplams: Would you code the NOS term when follicular lymphoma is favored? What would diagnostic confirmation be coded if a positive fine needle aspirate (FNA) is followed by a positive flow cytometry (ambiguous term)? See Discussion. |
Pathology reads: 1. FNA left groin lymph node tissue (smears and cell block): B-cell lymphoma, low grade. The concurrent flow cytometry (3-FC-16-288) identifies a monoclonal B cell population with immunophenotype of CD10++, CD5-, CD23-, CD20++ and unusual CD19-. Overall findings favor follicular lymphoma. FNA Specimen Adequacy: Evaluation for specimen adequacy: Immediate cytology smear review for specimen adequacy was performed at the time of the FNA procedure by pathologist. Smears reviewed from 2 passes in one reading. The specimen was adequate cytological evaluation. Surg Path Final Report Special Studies Immunohistochemistry (CD45, MCK, CD20, CD3, CD10, Bcl6, MUM1 \T\ Ki67) was performed on block 1A to confirm the diagnosis. All controls show appropriate reaction. Lymphoma cells are positive for CD45, CD20, CD10 and weakly positive for bcl6(+) and MUM1(+/-), and negative for MCK. CD3 highlights few T lymphocytes. Ki67 labeling index is low, less than 10%. The immunoprofile supports above diagnosis. Chromosomal study for t(14;18) translocation will be performed, and an addendum report will follow. Flow Final Report Comment: The lymphoma appears to be derived from germinal centre B cells. Together with the findings from the lymph node biopsy (3-FN16-416), follicular lymphoma is favored. However, negative CD19 and CD22 are unusual. |
Code histology as follicular lymphoma, NOS (9690/3). The clinician rendered the diagnosis after review of all information available, including histology, cytology, and immunophenotyping markers. Assign diagnostic confirmation code 1 based on histology. Diagnostic confirmation code 3 cannot be assigned in this case because the diagnosis included ambiguous terminology and the immunophenotyping is not unique to follicular lymphoma, NOS. |
