Reportability--Ovary: Is an "aggressive adult granulosa cell tumor with one of two lymph nodes positive for metastatic granulosa cell tumor" reportable?
Malignant granulosa cell tumor is reportable. The case described above is malignant as proven by metastasis to the lymph node.
CS Lymph Nodes--Head & Neck (Parotid): What code is used to represent a positive intraparotid or a periparotid lymph node for a parotid primary? See Discussion.
The CS scheme for parotid places intraparotid lymph nodes under code 10 as well as code 12. Periparotid lymph nodes are included under code 12. Should both intraparotid and periparotid lymph nodes be included under code 10 only?
For head and neck sites, several lymph node groups fall into the "Other groups" category. They are not included in the level I-VII groups. In the coding schemes for most (but not all) of the head and neck sites, the "other groups" category includes intraparotid and periparotid lymph nodes and is coded 12 (or 52).
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.Assign code 10 for a single positive intraparotid or periparotid lymph node. If multiple nodes are involved, assign the appropriate code from the 20 series.
A recent revision to the CS lymph nodes scheme for parotid places both intraparotid and periparotid lymph nodes under code 10. Please see the August 21, 2006 update to the CS staging manual.
Reportability--Skin: Is a pilomatrix carcinoma of the skin reportable if it is described as being a malignant diagnosis based on poor circumscription, infiltrative growth pattern, and focal abundant mitoses?
No. Pilomatrix carcinoma is not reportable to SEER. Please see page 1 of the 2004 SEER manual. Skin primaries with histology codes from 8090 to 8110 are not reportable. Pilomatrix carcinoma is coded 8110/3.
CS Tumor Size--Lung/Breast: Explain why the SEER instructions differ from the CS Manual regarding priority order of sources to code tumor size? See Discussion.
Regarding the 2004 SEER Manual, Appendix C, Site Specific Coding Modules, Lung and Breast. The priority of sources for coding tumor size is Pathology, Operative Report, PE, imaging for breast and pathology, operative, endoscopic, and imaging for lung. This differs from the CS Manual instructions.
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.For cases diagnosed in 2007 and forward, follow the instructions in the 2007 SEER manual and the CS manual.
2004 SEER Manual Errata/CS Lymph Nodes--Head & Neck: On page C-353, in the supraglottic larynx schema, there is no mention of Level IV nodes in the CS Lymph Node codes.
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.The CS Steering Committee is aware of this issue and is working to resolve it.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Skin: How many cases are to be abstracted and how is the histology field(s) coded for cases in which a fibrosarcoma arises in or transforms from a dermatofibrosarcoma protuberans? See Discussion.
1. If the fibrosarcoma occurs after DFP, and is called metastatic, is it a recurrence or is it a new primary? Example: Pt diagnosed in 7/05 with a high grade fibrosarcoma arising in a dermatofibrosarcoma protuberans. The path indicated "The presence of high grade fibrosarcoma, the extent of the tumor necrosis and the mitotic rate are all adverse prognostic findings that indicate a significant risk for mets." The patient had a recurrence in 8/06 called a low grade fibrosarcoma mets from prev." The DFP code is 8832/3 and a fibrosarcoma code is 8810/3. Our pathologist feels that the fibrosarcoma is a more aggressive tumor so should the case be coded to the 8810/3.
2. If DFSP has areas of fibrosarcoma, should it be coded to the latter because it is more aggressive? Example: Skin and subcutaneous tissue reads: Low grade sarcoma - tumor extends to margin. Comment: "Although the predominant pattern of this tumor is consistent with dermatofibrosarcoma protuberans, focal presence of hypercellularity and increased mitotic figures suggest transformation to Grade I fibrosarcoma. This progression, although focal, carries an increased risk of mets over classic DFSP. Code to 8810/31?
For tumors diagnosed prior to 2007:
Code histology to 8832/3 [Dermatofibrosarcoma protuberans] for both cases. DFSP with transformation to fibrosarcoma and DFSP with areas of fibrosarcoma are coded to 8832/3.
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.
Reportability--Colon: Is a pathologically confirmed "tubulovillous adenoma with high grade dysplasia" reportable if clinical diagnosis at the time of the subsequent re-biopsy states "follow-up for colon polyps with ca in situ"? See Discussion.
SINQ 20000245 states that high grade dysplasia is not synonymous with behavior code 2 (in situ). However, the 2004 SEER manual states that "cases clinically diagnosed are reportable. If the physician treats a patient for cancer in spite of the negative biopsy, accession the case."
A pathologic diagnosis has priority over a clinical diagnosis. According to the pathologist, this case is not reportable. A re-biopsy is not treatment.
Histology (Pre-2007)--Melanoma: How is a "plaque-like nodular spitzoid malignant melanoma" coded?
For tumors diagnosed prior to 2007:
Code histology to 8721 [nodular melanoma]. Essentially, "plaque-like nodular spitzoid malignant melanoma" is nodular melanoma. Code 8721 is the most specific ICD-O-3 histology code available for this diagnosis.
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.
Reportability: Is an AIN III that arises in perianal skin, skin tags or condyloma acuminatum reportable or must an AIN III arise in the anus or anal canal in order to be reportable?
AIN III arising in perianal skin [C445] is not reportable.
AIN III [8077/2] of the anus or anal canal is reportable.
Multiple Primaries--Lymphoma: Is a diagnosis of mycosis fungoides followed a year later with a biopsy proven diagnosis of anaplastic large T-cell lymphoma stated to represent a transformation of the previous mycosis fungoides reportable as one or two primaries?
For cases diagnosed prior to 1/1/2010:
This is one primary. Code the histology according to the original diagnosis, mycosis fungoides. The physician states that this one disease process started as mycosis fungoides and progressed into lymphoma. A physician's statement has priority over other sources in determining the number of hematopoietic primaries.
In October 2006, a committee will begin working on multple primaries among hematopoietic diseases. The committee will provide further guidance on dealing with disease transformation and other issues.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
