Multiple Primaries (Pre-2007): How many primaries? See Discussion.
5/05 perianal skin bx, 6/05 mapping bx perianal skin, 9/05 punch bx perianal skin: all positive for extramammary Paget Disease. 9/05 Perianal Excision of Paget w/V-Y flap repair. Path: Perianal and anal skin: Extramammary Paget disease associated with: Invasive adenoca of anal canal. Anal margins positive for invasive adenoca. Comment: invasive adenoca with local mucinous features involving the anal margin/end of specimen. This adenoca is in continuity with (associated with) extensively diffuse extramammary Paget disease. Unclear whether the adenoca represents a rectal primary with spread to perianal area, anal gland adenoca or mets. 12/05 AP resection-no residual Paget or invasive neoplasm.
For tumors diagnosed prior to 2007:
There is one primary.
Code the histology to 8542 [Paget disease, extramammary]. Code the primary site C210 [anus]. Histology rule 7 on page 87 of the 2004 SPCM applies in this case.
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--Hematopoietic, NOS: Is a "Myelodysplasia, refractory macrocytic anemia with multilineage dysplasia" reportable?
For cases diagnosed prior to 1/1/2010:Yes, myelodysplasia, refractory macrocytic anemia with multilineage dysplasia is reportable. This is a type of refractory anemia. Refractory anemia is reportable.
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.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: How many primaries are to be abstracted and how is the histology field(s) coded when a nipple biopsy demonstrates Paget disease and a separate biopsy in the same breast demonstrates inflammatory breast carcinoma? See Discussion.
Should Paget disease be coded as the histology because it has a higher histology code than inflammatory carcinoma?
For tumors diagnosed prior to 2007:
Abstract the inflammatory carcinoma as one primary and the Paget disease as a separate primary. The first three digits of the histology codes for these histologies are different (8530 and 8540). Therefore, these are separate primaries.
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--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.
Collaborative Staging--Lung: Given that the AJCC lung TNM is not applicable for a high grade sarcoma of this site, how do we code Collaborative Stage for this site/histo combination when the pathologist indicates a TNM stage of T2bN0M0=stage III, using AJCC Soft Tissue Sarcoma schema?
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.
Use the lung schema to code CS for sarcoma of the lung. Complete the CS information as best you can from the medical record WITHOUT using the TNM Soft Tissue Sarcoma staging form. Visceral sarcomas are specifically excluded from soft tissue sarcoma TNM staging and sarcomas are excluded from the TNM staging for lung.
Sarcoma is listed on the Histology Exclusion Table for lung. When a case is coded in Collaborative Staging and the histology is on the exclusion list, SEER Summary Stage 1977 and 2000 can be assigned. For these cases, TNM will not be calculated and displayed results will be "T NA N NA M NA and Stage Group NA".
Histology (Pre-2007)--Melanoma: Is the code 8740/3 [malignant melanoma in a junctional nevus] to be used when the pathologic diagnosis is "malignant melanoma arising in a compound nevus"?
For tumors diagnosed prior to 2007:
Assign code 8720/3 [malignant melanoma, NOS] for malignant melanoma arising in a compound nevus. A compound nevus is not the same as a junctional nevus.
ICD-O-3 does not have a specific code for melanoma in a compound nevus. Assign the code for the type of melanoma specified; for example, NOS, superficial spreading, etc.
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.
MP/H Rules/Histology--Breast: Which report and diagnosis should be used to code the histology if an excisional biopsy that removes the majority of the tumor has a diagnosis of "carcinoma," and the subsequent lumpectomy diagnosis is "microscopic residual disease consistent with infiltrating duct carcinoma"?
For cases diagnosed 2007 or later, code histology for this case to 8010 [carcinoma]. The histology is coded from the pathology report with the most representative specimen (the most tumor tissue) even when the most representative specimen has a less specific histology.
Reportability/Terminology--Prostate: Is the diagnosis of "atypical glands suspicious for adenocarcinoma" sufficient to report a prostate cancer if a note states that there is "insufficient atypia to establish a definitive diagnosis of malignancy"? See Discussion.
Date of report is July 2005. One positive specimen of 12.
Specimen 6: Diagnosis = Prostate tissue with a small focus of atypical glands suspicious for adenocarcinoma. Note. There is insufficient cytologic and/or architectural atypia to establish a definitive diagnosis of malignancy. Negative basal cell staining with cytokeratin... in atypical glands is consistent with the diagnosis of suspicious for adenocarcinoma. In addition, the diagnosis is suppported by a positive staining for alpha-methyl COA racemase (P504S), a recently discovered marker that is preferentially expressed in prostate cancer...
This case is reportable. The diagnosis states "suspicious for adenocarcinoma." "Suspicious for" is a reportable ambiguous term.
The additional stains supported this "suspicious" diagnosis. A more definitive diagnosis could not be made based on this specimen.
Reportability--Brain and CNS: Does a neurofibroma actually arise in peripheral nerve roots like a schwannoma even if it is referred to as a "C6-T1 intradural spinal cord tumor" and is therefore not reportable?
Schwannomas and neurofibromas of the peripheral nerves are not reportable. Schwannomas of the nerve root or spinal dura are reportable.
