Primary Site--Bladder: What subsite is used for fundus of the bladder?
As of November 2005, Code fundus of bladder to C678 [overlapping lesion of bladder]. Opinions vary regarding the definition of bladder "fundus." However, according to our pathologist consultant, fundus includes posterior, anterior and lateral walls and dome. Fundus does not include the trigone.
A correction to page C-595 of the 2004 SEER manual will be included in the next errata.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed with small lymphocytic lymphoma in 1996, received chemotherapy on and off for 15 years due to relapses, and was subsequently diagnosed with diffuse large B-cell lymphoma in 2012?
Per Rule M10, this case should be accessioned as two primaries. According to Rule M10, one is to abstract as multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm AND there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis.
The histology for the 1996 chronic neoplasm is coded to 9670/3 [small lymphocytic lymphoma]. The histology for the 2012 acute neoplasm is 9680/3 [diffuse large B-cell lymphoma].

MP/H--Bladder: Are 8130 and rule H12 correct for this case? Bladder with papillary urothelial carcinoma with squamous cell differentiation.
Rule H8 applies, code the histology with the numerically higher ICD-O-3 code which is papillary transitional cell carcinoma, 8130.
Based on the information provided, there is a single bladder tumor, papillary urothelial carcinoma with squamous cell differentiation. Urinary sites rule H12 does not apply because this is a single tumor, not multiple tumors. In the single tumor H rules, H3 does not apply as this rule does not include papillary transitional cell carcinoma. Rule H4 is papillary carcinoma or papillary transitional cell carcinoma and refers you to Table 1. Table 1 does not list papillary urothelial carcinoma with squamous cell differentiation because there is no ICD-O-3 code for this histology. Table 1 does list transitional cell carcinoma with squamous differentiation as code 8120, however, the papillary transitional cell carcinoma is the higher code, 8130. We will review this situation for the next version of the rules.
CS Extension/CS Lymph Nodes--Lung: How are these fields coded if a lobectomy path specimen indicates that two intrapulmonary lymph nodes are involved by direct extension from the primary tumor?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code regional lymph node involvement in CS lymph nodes even when the lymph nodes are involved by direct extension. Do not code direct extension to lymph nodes in CS extension.
MP/H Rules/Histology--Colon: What histology would be coded when the right colon demonstrates a combined adenocarcinoma and high grade small cell neuroendocrine carcinoma [forming the dominant component] arising in a villotubular adenoma and the liver biopsy demonstrates metastatic high grade small cell neuroendocrine carcinoma?
For cases diagnosed 2007 or later, start with rule H1 in the Single Tumor module. Stop at rule H4. Assign code 8263 [adenocarcinoma in tubulovillous adenoma].
Stop at the first rule that applies. Code histology based on a specimen from the primary site whenever available.
MP/H Rules/Histology--Lung: What is the correct histology code for this lung tumor? FINAL PATHOLOGIC DIAGNOSIS: CT-guided Rotex and Franseen needle biopsies: Positive for malignancy, consistent with adenocarcinoma. Comment: the adenocarcinoma present also shows rare CD56 staining which indicates a neuroendocrine component.
Is this a mixed histology? 8045/3? 8244/3?
Assign histology code 8140/3, adenocarcinoma, based on the final diagnosis. The neuroendocrine component in this case is not another histology, nor is it a more specific adenocarcinoma. "Component" is not one of the words that we use to indicate a more specific histology.
Histology--Heme & Lymphoid Neoplasms: How is histology coded for a pathologic diagnosis of "B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma" that was clinically referred to as a "double hit lymphoma"?
Code histology to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Per the Alternate Names section in the Heme DB, B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is one of the synonyms for for DLBCL.

Scope of Regional Lymph Node Surgery: If a named regional lymph node is aspirated should this field be coded to 1 [Regional lymph node removed, NOS], as is stated on page 127 of the SEER Program Code Manual, or should this field be coded to a more specific code when that is available (e.g. Lung primary code 3 [Ipsilateral mediastinal and/or subcarinal nodes])?
For cases diagnosed 1/1/2003 and after: A generic scheme was created for the Scope of Regional Lymph Node Surgery field. As a result, there no longer are codes available that represent specific named lymph node chains. Code aspiration of a lymph node to 1 [Biopsy or aspiration of regional lymph node, NOS].
Computed Ethnicity: Should the Name--Alias field be used when generating Computed Ethnicity?
No, "Alias" is not used and should not be used to generate Computed Ethnicity. Computed Ethnicity records the ethnicity based on last name and/or maiden name using a computer algorithm. Alias is not part of the algorithm.
Reportability/Histology--Soft Tissue: Is atypical spindle cell neoplasm, primitive myxoid mesenchymal tumor of infancy (PMMTI) from the soft tissue of the leg in August of 2019, reportable?
Primitive myxoid mesenchymal tumor of infancy (PMMTI) is reportable. PMMTI is listed in the new WHO 5th edition Classification of Soft Tissue and Bone Tumors under round cell sarcomas. This is a variant of BCOR sarcomas. There is a new ICD-O histology code assigned for cases diagnosed in 2022 or later (9368/3). Code this 2019 case to round cell sarcoma, undifferentiated 8803/3. Use text fields to explain the details.
