Primary site--Kidney, renal pelvis: Should primary site be coded C809 [unknown] or C649 [kidney] when a patient is diagnosed with renal cell carcinoma in a transplanted kidney?
Code the primary site to C649 [kidney]. Per the SEER Manual, code the site where the neoplasm originated. There are no separate instructions for coding primary site for transplanted organs. This patient's renal cell carcinoma originated in the kidney [C649].
Multiple primaries--Heme & Lymphoid Neoplasms: Is this abstracted as one primary or two?
5/2/13 Bone Marrow biopsy: myelodysplastic syndrome with approaching to acute myeloid leukemia with del 5q and 7q deletions. FISH: deletion of chromosome 5q and deletion of chromosome 7q detected.
I checked the Heme DB manual and there is no term "With approaching to". I checked the Multiple Primary calculator and it says new primary. My interpretation is that the myelodysplastic syndrome is in the process of transforming to acute myeloid leukemia.
Abstract a single primary, myelodysplastic syndrome with del 5q and 7q deletions (9986/3). This neoplasm can transform to acute myeloid leukemia (AML); however, "with approaching to" cannot be used to report this AML.
Reportability--Pancreas: Is a solid pseudopapillary neoplasm of the pancreas reportable?
Solid pseudopapillary neoplasm of the pancreas is reportable. According to the WHO classification, it is a "low-grade malignant neoplasm…[which] frequently undergoes hemorrhagic-cystic degeneration and occurs predominantly in young women."
Assign topography code C25 with the appropriate 4th digit. Code the histology as 8452/3.
Reportability/Recurrence (Pre-2007)--Bladder: If a patient has had recurrent invasive bladder cancers since 1971, should the latest recurrence in 2003 be SEER reportable because the case has yet to be reported to SEER?
For tumors diagnosed prior to 2007:
Because this 2003 recurrent bladder cancer was initially diagnosed prior to 1973, it is not reportable to SEER.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms.

Histology: What is the histology code for a soft tissue thigh mass that was diagnosed as Ewing sarcoma/PNET, primitive neuroectodermal tumor?
The histologies stated for this case are Ewing sarcoma (9260) and PNET, primitive neuroectodermal tumor,(9364)*. Use the Other Site Rules, starting with H8. Stop at H17 and assign the higher histology code -- 9364/3 [Peripheral neuroectodermal tumor].
*The term "PNET" is used for two different tumors. One is primitive neuroectodermal tumor (9473) and pertains to brain tumors per ICD-O-3 review. The other is peripheral primitive neuroectodermal tumor (pNET or PPNET 9364) and pertains to bone or soft tissue tumors. This case is stated to be soft tissue and Ewing sarcoma, so it is 9364 rather than 9473.
Histology--Breast: Please confirm the morphology code for a diagnosis of "encapsulated papillary carcinoma" of the breast. Several articles on the internet lead me to believe it is the same as an intracystic carcinoma, code 8504/2 (our case shows no evidence of invasion).
You are correct in coding 8504/2 for this case. Per the 4th Edition WHO Tumors of the Breast, encapsulated papillary carcinoma (EPC) of the breast is synonymous with intracystic or encysted papillary carcinoma. It is a variant of ductal carcinoma in situ (DCIS).
Reportability--Anus: Is a final diagnosis on a pathology report of "squamous cell carcinoma of the anus, NOS" assumed to be a skin of anus primary or a primary of the anus?
Squamous cell carcinoma of the anus is reportable unless known or stated to be skin of anus.
Reportability/In situ--Prostate: Has there been a change in reportability for prostatic intraepithelial neoplasia (PIN III) (C619)? The 2018 SEER Manual notes: Collection stopped effective with cases diagnosed 01/01/2001 and later; however, on the casefinding list effective 10/01/2019, code D07.5, carcinoma in situ of prostate, is listed as reportable.
PIN III is not reportable in accordance with the 2018 SEER Manual; however, carcinoma in situ of the prostate is reportable as they represent different histology codes. The casefinding list is used to search for reportable cases and is not the same as a reportable list.
