Report Question ID Question Discussion Answer Year
20081138 MP/H Rules/Histology--Lung: What is the correct histology code for a neuroendocrine neoplasm described as a carcinoid and also referred to as oncocytic? See Discussion.

Left mainstem bronchus mass excised: metaplastic endobronchial mucosa with submucosa containing an infiltrating poorly diff malignant tumor. Origin of tumor is not identified in overlying mucosa. IHC stains will be performed.

Addendum #1. IHC stains show well diff neuroendocrine neoplasm, favor carcinoid. Recommend sending this to expert in lung neoplastic pathologist.

Addendum #2. (lung path specialist) oncocytic neuroendocrine neoplasm.

Is this 8246 or 8290 or something else?

 For cases diagnosed 2007 or later, code as 8246 [Neuroendocrine carcinoma, NOS]. According to our pathologist consultant, the neuroendocrine description is more specific than the oncocytic description in this case. 2008
20081025 MP/H Rules/Histology--Anus: What is the correct histology code and MP/H histology rule to use for AIN-3 arising in a polyp? See Discussion.

Patient has colonoscopy with excision of small 5mm polyp in rectum (no mention of anus or anal canal); path reads out: AIN-3 (anal intraepithelial neoplasm grade 3).

In coding the histology using the "Other Sites" rules, H2 would be the first rule that applies for this case. However, we lose the fact that the AIN-3 arose in a polyp (H3). Is this how SEER wants these cases coded?

 For cases diagnosed 2007 or later, apply rule H2 and assign histology code 8077/2 (squamous intraepithelial neoplasia, grade III). Apply the rules in order, H2 precedes H3. 2008
20081120 MP/H Rules--Sarcoma: How many primaries should be abstracted for chondrosarcoma of right toe in 2002, of right lower leg in 2006 and right tibia in 2007? See Discussion. A patient had a myxoid chondrosarcoma of the right toe in 2002. This was amputated and staged as T2 - high grade. Patient had a recurrence in the lower right leg in 2006. At this time he had a below knee amputation. The tumor in 2006 was stated to be similar histologically to the 2002 tumor with pathologic comparison done. Then in 2007 the patient presents with pain in right knee and stump. CT says compatible with recurrent disease, but no copies of path sent. Patient then had an above knee amputation, with diagnosis of clinically recurrent chondrosarcoma of tibia. How many primaries should be abstracted? Is 2007 diagnosis a new primary?

For cases diagnosed 2007 or later:

Abstract two primaries in this case, 2002 and 2007.

The first primary was diagnosed in 2002. The 2006 diagnosis would not be a new primary according to the rules in effect at that time (2004 SEER manual, page 11, rule 5, exception 1).

Use the current MP/H rules to compare the 2007 diagnosis to the 2002 diagnosis. Start with rule M3 and stop at rule M10. The 2007 diagnosis is a separate primary.

20081084

Reportability: Is a tubular adenoma reportable if the final diagnosis is "high grade atypia" and the diagnosis comment is "atypia limited to muscularis mucosa areas of pseudostratification [formerly qualifying for carcinoma in situ]"?

This case is not reportable.

The pathologist would need to include "carcinoma in situ" as part of the final diagnosis in order for this case to be reportable.

20081074 Primary site/Histology: Does SEER accept the site/type combination of lymph nodes (C77.0-C77.9) with the histology of either 9823 (B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma) or 9827 (Adult T-cell leukemia/lymphoma)? See Discussion. There is a discrepancy between the SEER Site/Type table and the CS histology codes under Lymph Nodes.

For cases diagnosed prior to 1/1/2010:These are not "impossible" site/histology edits. You can override them. However, if the lymph nodes are involved and a lymphoma histology is available, the lymphoma histology should be coded rather than leukemia histology. For example, assign histology code 9670 (Malignant lymphoma, small B lymphocytic, NOS) instead of 9823 (B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma) if the disease is identified in the lymph nodes.

For cases diagnosed 1/1/10 and later, 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.

20081019 Multiple Primaries--Lymphoma: How many primaries are abstracted for a patient with a 1995 periaortic lymph node biopsy showing lymphocytic lymphoma, diffuse small cleaved probable intermediate grade B cell positive, followed by stomach biopsies on 6/18/05 showing diffuse large B cell lymphoma and on 6/24/05 showing malignant lymphoma, tumor cells positive for [CD20] B cell respectively?

For cases diagnosed prior to 1/1/2010:There are two primaries:

  • Lymphocytic lymphoma, diffuse, intermediate in 1995

  • Diffuse large B-cell lymphoma in June, 2005

    • According to the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, 9673 [Malignant lymphoma, lymphocytic, diffuse, intermediate] and 9680 [Malignant lymphoma, large B-Cell, diffuse] are separate primaries. Again, according to the table, 9680 [Malignant lymphoma, large B-Cell, diffuse] and 9591 [Malignant lymphoma, non-Hodgkin, NOS] are the same primary.

    For cases diagnosed 1/1/10 and later, 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.

    		20081056 MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?

    For cases diagnosed 2007 or later:

    For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.

    This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.

    		20081051 MP/H Rules/Histology--Prostate: Path said adenocarcinoma of the prostate with an endometroid adenocarcinoma component. What histology code is used?

    For cases diagnosed 2007 or later:

    Assign code 8500 [duct carcinoma].

    According to The World Health Organization (WHO), the term endometrioid carcinoma of the prostate is now called Prostate Duct Carcinoma.

    Using Rule H11 (one type), code 8500 (duct carcinoma) for this rare type of tumor. Do not stop at Rule H10 because this is not acinar.

    MP/H Rules--Breast: How many primaries for the following?

    Breast lumpectomy: Three foci of invasive ductal carcinoma.

    Tumor nodule #1 - Invasive ductal carcinoma.

    Tumor nodule #2 - Invasive ductal carcinoma with tubular features.

    Tumor nodule #3 - Invasive tubular carcinoma.

    See Discussion.

    According to the MP/H rules, this case is reportable as three primaries with histologies coded 8500, 8523 and 8211. However, our QC staff is having a problem accepting this. When the pathologist specifies that a ductal carcinoma has tubular features or is tubular type, isn't s/he saying that tubular is a type of duct? In addition, the first line of the FDx states, "Three foci of ductal carcinoma," which indicates that the pathologists interprets the three nodules to be ductal carcinoma.

    For cases diagnosed 2007 or later:

    These three tumors are three separate primaries. Rule M12 applies.

    According to the 2007 MP/H rules, tubular carcinoma is not a type of duct carcinoma.

    Among the paramount reasons for writing the MP/H rules are the non-standard usage of nomenclature by physicians and the inconsistency in interpretation of these non-standard phrases. The MP/H rules must be applied consistently by each cancer registrar in order for data to be comparable across registries.

    		20081045 MP/H Rules--Melanoma: How is histology coded for a regressing melanoma? See Discussion.

    How is histology to be coded for the following tumors?

    Example 1: Path showed malignant melanoma Histologic type: superficial spreading. Regression: present.

    Example 2: Shave, mid back: malignant melanoma, lentigo melanoma type, level II, regression: present and prominent.

    For cases diagnosed 2007-2014:

    Apply MP/H Melanoma Histology Coding rule H5 and code the histologic type of the melanoma.

    Code example 1 as 8743 [Superficial spreading melanoma].

    Code example 2 as 8742 [Lentigo maligna melanoma].
