20220014 | Surgery of Primary Site--Melanoma: How is Surgery of Primary Site coded when a path specimen is labeled as a “staged excision” for a cutaneous melanoma. See Discussion. |
Patient was diagnosed on biopsy with lentigo maligna melanoma of the nasal dorsum. The only available documentation of the subsequent surgery is a single pathology report with the nasal dorsum “staged excision (debulking specimen)” and four additional “staged excision” specimens of the same site. Is it safe to assume this is a Mohs surgery? Would it be safe to assume staged excisions of sites other than skin of face, are also Mohs surgery? |
Interpret a "staged excision" for cutaneous melanoma as a type of Mohs surgery. Skin surgery codes are currently under review and revision. Document details in available text fields. |

20210028 | Histology/Biliary tract--Ampulla of Vater: What is the histology code for Intra ampullary papillary-tubular neoplasm in association with microinvasion? See discussion. |
Patient was diagnosed on 01/2020, and primary site on the pathology report is Ampulla of Vater (C241). Synoptic Report states histology as: Intra ampullary papillary-tubular neoplasm in association with microinvasion. I have reviewed the ICD-O-3 coding table and found histology Intraductal tubulopapillary neoplasm (C25_) code 8503/2. Based on the Matrix principle (Rule F on the ICD-O-3), I will change the behavior to 3 and code as 8503/3. If I look in ICDO-3, Tubulopapillary adenocarcinoma is coded 8263/3. |
Assign code 8163/3. Based on the microinvasion, the correct term for this neoplasm is pancreatobiliary-type carcinoma. Unfortunately, WHO did not provide all synonyms or related terms for some of the new ICD-O codes. Pathologists may continue using non-preferred terminology as well. |

20100017 | MP/H Rules/Multiple primaries--Prostate: Does adenosquamous carcinoma found in the prostate represent a second primary in a patient previously diagnosed with adenocarcinoma of the prostate? See Discussion. | Patient was diagnosed many years ago with adenocarcinoma of the prostate and treated with hormonal and radiation therapy. The patient recently underwent a TURP and is found to have adenosquamous carcinoma of the prostate. The pathology report comment states squamous carcinoma of the prostate is rare and is often associated with a history of hormonal or radiation therapy. There is no information indicating a history of a squamous carcinoma in the urinary system that could have involved the prostatic urethra.
Would the MP/H rules make this a second primary with the histology of 8560/3 [adenosquamous carcinoma]? |
For cases diagnosed 2007 or later, based on the limited information available for this unusual case, abstract a second prostate primary and code the histology as adenosquamous carcinoma. Rule M3 does not apply in this case. Apply rule M10. | 2010 |

20100101 | Multiple primaries--Heme & Lymphoid Neoplasms: Is a 10/2010 diagnosis of accelerated phase of CML following a 4/2010 diagnosis of blast phase CML a new primary? See Discussion. | Patient was diagnosed in the blast phase of CML on a 4/2010 bone marrow biopsy. Pt failed Gleevec and progressed to the accelerated phase of CML in 10/2010.
Is this a single primary? This is not addressed in the hematopoietic rules. If this is a multiple primary, what rule should be applied? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M2 this is a single primary because there is only a single histology represented for this case.
Under the Alternate Names section in the Heme DB for chronic myelogenous leukemia (CML), NOS [9863/3 and chronic myelogenous leukemia, BCR-ABL1 positive [9875/3] it indicates CML-blast phase, CML-accelerated phase and CML-chronic phase are all synonyms for CML, NOS. Any combination of these terms diagnosed represents one disease process. The Gleevec was given to prevent or delay progression to the accelerated phase.

20230050 | Reportability/Histology--Soft Tissue: Is a diagnosis of Myofibroblastoma with sarcomatous transformation a reportable malignancy? See Discussion. |
Patient was diagnosed in September 2022 via excision of a 12 cm pelvic mass with final diagnosis of Myofibroblastoma with sarcomatous transformation. Diagnosis comment states, “Most of the tumor is composed of conventional features of myofibroblastoma. However, a focal area demonstrates increased cellularity, fascicular growth and increased mitotic activity (up to 11 per 10 hpf), consistent with sarcomatous transformation (morphologically low to intermediate grade).” Is this sarcomatous transformation describing a malignant transformation from an otherwise benign histology? If so, how should histology be coded in this case? |
Do not report the case. The histology is 8825/0 based on the example provided and not reportable. Myofibroblastoma with sarcomatous transformation is a rare, benign condition, sometimes referred to as sarcomatous features. A malignant tumor would be referred to as a myofibroblastic sarcoma. |

20240040 | First course treatment--Kidney: How should the different treatment fields be coded if surgery is planned but cancelled due to patient noncompliance, then the tumor is treated with ablation, and eventually surgery is given due to residual disease? See Discussion. |
Patient was diagnosed in July 2022 with biopsy confirmed left kidney renal cell carcinoma. Initially, partial nephrectomy was planned for February 2023 but canceled at the last moment due to the patient’s “history of narcotic use.” The details of that cancellation were otherwise unclear. It appears the treatment plan was changed due to patient non-compliance. Patient then had cryoablation of the tumor in May of 2023. Subsequent imaging in October found residual tumor, but no disease progression was noted. Again, additional ablation was offered but patient decided on surgical treatment which did not occur until December 2023. Is the cryoablation second course due to a change of plan if there is no disease progression, recurrence, or treatment failure? If the cryoablation is first course treatment, then would the partial resection also be first course treatment because it was documented as the treatment plan? |
The treatment with cryoablation is second course. Once the initial treatment plan is changed, everything after the change is no longer first course of treatment. If the cryoablation was not mentioned as part of the original treatment plan, it is second course. |

20100088 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient has 2005 diagnosis of multiple myeloma diagnosed returns in 2010 with extramedullary plasmacytoma and a bone marrow biopsy showing plasma cell dyscrasia that is clinically stated to "consistent with a relapse of myeloma"? See Discussion. | Patient was diagnosed in 2005 with multiple myeloma and following stem cell transplant 2005 was in complete remission.
On 2/1/10 an excisional biopsy of a soft tissue right flank mass showed plasmacytoma. On 3/2/10 the bone marrow biopsy was stated to be consistent with plasma cell dyscrasia. An outside attending physician stated the bone marrow biopsy was consistent with a relapse of myeloma. There was no radiologic evidence of disease elsewhere as of Feb 2010, only the soft tissue right flank mass. Patient initially presented for post-op radiation to the right flank and was treated 3/29/10. On 8/6/10 a biopsy of a right perinephric mass was positive for plasmacytoma. Subsequent xray on 8/16/10 of the right tibia and fibula showed lytic lesion consistent with progression of myeloma.
Using the Hematopoietic Database, the plasmacytoma in 2/1/10 is a second primary. How do the rules apply to the perinephric soft tissue disease and right tibia lesion? Are they separate new primaries? Or is all of this simply a recurrence of the original 2005 diagnosis as the attending physician states? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Accession a single primary with the histology coded to 9732/2 [multiple myeloma]. The disease discovered in 2010 represents further advancement of former disease. Per the Abstractor Notes section in the Heme DB, it states that bone marrow involvement, lytic bone lesions, and bone tumor masses of plasma cells are common. Under the Recurrence and Metastases section in the Heme DB it further states that extramedullary (in tissue other than the bone) involvement is a generally a manifestation of advanced disease. This case is an example of such a situation.

20130109 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2004 diagnosis of acute myeloid leukemia is followed by a 2013 diagnosis of myeloid sarcoma? See Discussion. |
Patient was diagnosed in 2004 with acute myeloid leukemia [9861/3] and treated with chemotherapy and transplant. Now the patient has a biopsy of an umbilical mass that is positive for myeloid sarcoma (granulocytic sarcoma) [9930/3]. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Accession a single primary, acute myeloid leukemia [9861/3] diagnosed in 2004 per Rule M3.
When there is a myeloid sarcoma diagnosed simultaneously or after a leukemia of the same lineage, it is a single primary. The myeloid sarcoma is actually caused by the AML progressing. The myeloid cells in the bone marrow or blood literally "seep out" and implant in the tissue.

20240032 | Update to Current Manual/Reportability--Biliary Tract: Is a diagnosis of high grade dysplasia of the gallbladder reportable? See Discussion. |
Patient was diagnosed March 2024 with high grade dysplasia of the gallbladder during excision for clinical history of acute cholecystitis and obstruction. Per the STR, Table 10 for Gallbladder and Extrahepatic Bile Duct Histologies shows Biliary intraepithelial neoplasia, high grade as code 8148/2. High grade glandular intraepithelial neoplasia of the biliary tract is also code 8148/2. Recent SINQ 20240021 (GI specific) indicates high grade dysplasia is reportable as high grade glandular intraepithelial neoplasia (8148/2) for stomach, small intestine, and esophagus. Does the same hold true for gallbladder? If so, then it appears there is a conflict between STR and Appendix E2. However, using the logic of SINQ 20240021 for this site would appear to contradict Appendix E2 which indicates high grade dysplasia in sites other than stomach, intestine, and esophageal sites is not reportable. If we can code high grade dysplasia of GI sites to 8148/2, should we accession high grade dysplasia of the gallbladder and other biliary sites in a similar manner? If so, then Appendix E needs to be modified. |
Report biliary intraepithelial neoplasia (dysplasia), high grade. As noted in SINQ 20240021 and the Other Sites Solid Tumor Rules, Rules H4/H26, the listed sites may not include all reportable neoplasms for 8148/2. We will update the Other Sites Solid Tumor Rules to reflect this code as well as make revisions in the next release of the SEER Manual. |

20240031 | Reportability/Histology: Is a diagnosis of non-lung neuroendocrine tumorlet reportable? See Discussion. |
Patient was diagnosed March 2023 with a neuroendocrine tumorlet of the rectum measuring 0.8 mm via excisional biopsy during colonoscopy. Prior SINQ 20160011 (stomach specific) indicates microcarcinoid and carcinoid tumors are reportable. Microcarcinoid is a designation for neuroendocrine tumors of the stomach when they are less than 0.5 cm. in size. Is the current rectal tumor a reportable gastrointestinal neuroendocrine tumor if it is less than 5 mm (i.e., is a neuroendocrine tumorlet equivalent to a microcarcinoid)? |
Do not report neuroendocrine tumorlet of lung and non-lung sites. Microcarcinoid and carcinoid tumors are reportable. Tumorlet is a tumor of neuroendocrine differentiation, defined by size < 5 mm in diameter, mitotic count < 2 mitoses/2 mm², and absence of necrosis. Microcarcinoid is a designation for neuroendocrine tumors when they are less than 0.5 cm. in size. The term "tumorlet" is used in a number of other settings, referring to small tumors (usually < 0.5 cm), and does not necessarily mean carcinoid tumor. The term microcarcinoid tumor is not equivalent to neuroendocrine tumorlet. |
