20120071 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded and what rule applies if the patient has involvement of multiple organs and one lymph node chain with diffuse large B-cell lymphoma? See Discussion. |
In 2011 the patient was diagnosed with a 15 cm mass involving the terminal ileum, cecum and adjacent mesentery. The pathology was positive for diffuse large B-cell lymphoma. A staging PET/CT revealed a mass at the base of tongue and a left cervical lymph node. The biopsy of the base of tongue also showed DLBCL. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Apply rule PH22 to code the primary site to C779 [lymph nodes, NOS]. While the pathology does not indicate that this particular case represents a B-cell lymphoma, unclassifiable with features intermediate between DLBCL and Burkitt variant, in the Abstractor Notes section of the Heme DB for diffuse large B-cell lymphoma it does indicate that its presentation, "may have lesions in ileocecal region or jaws. Bone marrow and peripheral blood may be involved. Patients present with lymphadenopathy or mass lesions in extranodal site." This patient does have involvement of two extranodal sites and involvement of regional lymph nodes for only one of those sites. PH22 indicates one is to code the primary site to C77.9 [lymph nodes, NOS] when lymphoma is present in multiple organs and lymph nodes that are not regional for that organ and the origin cannot be determined even after consulting the physician. There are two extranodal sites of involvement and only one chain of lymph nodes is regional to one of those sites so this rule applies.

20120081 | Reportability: Is VIN II-III reportable? |
For cases diagnosed 2021 and later VIN II-III is reportable based on ICD-O-3.2 which lists squamous intraepithelial neoplasia, grade II as 8077/2 making it reportable. Also see SINQ 20120094. |

20120001 | Multiple primaries/Recurrence--Heme & Lymphoid Neoplasms: How many primaries are abstracted if a patient was diagnosed with diffuse large B-cell lymphoma in 2001 and was diagnosed with diffuse large B-cell lymphoma involving the larynx in 2011? See Discussion. | Does the medical oncologist's statement that this is a second malignancy, rather than a recurrence, given the length of the disease-free interval, affect the number of primaries abstracted? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Abstract a single primary per Rule M2; a single histology is a single primary diagnosed. The histology code for both the 2001 and 2011 diagnoses is 9680/3[diffuse large B-cell lymphoma]. Case is coded as diagnosed in 2001.
The hematopoietic physician experts say that the issue with lymphomas is that the patient may be disease-free then recur years later. Even though years have passed, this is still a recurrence or relapse. Currently, there are no molecular markers that are able to distinguish "new primaries" from recurrences. There are also no established criteria for timing rules that could be used to determine a new primary from a recurrence.

20120045 | Primary site--Heme & Lymphoid Neoplasms: What is the primary site of a diffuse large B-cell lymphoma described on a PET and an abdominal CT scan as a large pelvic mass displacing bladder and uterus, inseparable from anus, right pelvic sidewall, cervix and bilateral ovaries and per the clinician as stage IIE? See Discussion. | PET: large pelvic mass displacing bladder and uterus, inseparable from anus, right pelvic sidewall, cervix and bilateral ovaries. Diffuse abnormal uptake within this mass as well as the adjacent structures. No regional hypermetabolic adenopathy is noted and no imaging evidence of distant metastatic disease. The PET also demonstrated diffuse abnormal uptake within the pelvic mass as well as the adjacent structures.
CT abdomen: large pelvic mass invading vagina and inseparable from the anus, right pelvic sidewall, cervix and bilateral ovaries.
MD states: "stage IIE with invasion of vagina." |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule 18, code the primary site to C775 [pelvic lymph nodes]. Per Rule PH18, code the primary site to the specified lymph node region when the site of lymphoma is described only as a mass. This rule also indicates that the Code pelvic lymph nodes [C775] when the lymph nodes are described as a pelvic mass.
This rule has been effect for SEER for over 20 years. It is based on the fact that a number of lymphomas that originate in nodes are not diagnosed until those nodes become matted or fixed. The presentation is then one of a "mass" in those nodal regions.

20120057 | Reportability--Appendix: Is a low grade mucinous neoplasm of uncertain malignant potential with an in situ mucinous cystadenoma component reportable? See Discussion. | The patient was diagnosed with pseudomyxoma peritonei and the pathology report final diagnosis stated, "Low grade mucinous neoplasm, of uncertain malignant potential, involving a dilated appendix (5cm) with the following features: In situ mucinous cystadenoma component is identified, with low-grade cytology of neoplastic epithelium." Does the presence of an in situ component make this mucinous cystadenoma of the appendix reportable based on the ICD-O-3 matrix rule? | This diagnosis is not reportable. Cystadenoma is not reportable. The "in situ" description in this case does not make cystadenoma reportable.
According to our expert pathologist consultant, this is a "non-invasive, low grade, epithelial proliferation in an often cystic appendiceal tumor, 8480/1. If this has leaked or ruptured it can seed the peritoneal cavity causing pseudomyxoma peritonei." |

20120085 | Reportability--Ovary: Are mature teratomas of the ovary reportable? See Discussion. |
Per a NAACCR Webinar from February 2011 (Testis), "All adult (post-puberty) pure mature teratoma tumors are malignant and should be coded 9080/3.' Does this apply to ovarian cases? The medical record entries all seem to indicate this a benign process. Should this NAACCR Webinar info be applied specifically to testicular cases? Would this be a reportable case if the primary site were testis? The patient also has a history of medullary carcinoma of the thyroid. SINQ 20100052 indicates a thyroid primary may present in an ovarian teratoma. Would this be reportable, or must there be mention of the histology other than, or in addition to, the mature teratoma? |
Mature teratomas in the ovary are benign [9080/0]. For testis, mature teratoma in an adult is malignant (9080/3); however, mature teratoma in a child is benign (9080/0). With regard to the thyroid issue, from the information above, the medullary carcinoma in the patient's thyroid is clearly a separate event. According to our expert pathologist consultant, "thyroid tissue is one of the many tissue types that may be seen in teratomas. When the teratoma has exclusively or predominantly thyroid tissue the term struma ovarii is used Adenoma or carcinoma of the thyroid type may be seen in this thyroid tissue. If medullary carcinoma were present in the thyroid tissue in the ovary/teratoma, there would be mention of it in the path report." |

20120062 | MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if a patient has a history of breast cancer in 2006 treated with bilateral mastectomies and in 2011 is found to have invasive carcinoma in "breast tissue, right lumpectomy"? See Discussion. |
Patient was originally diagnosed in June 2006, with right breast cancer and underwent lumpectomy and chemotherapy. This was followed by a bilateral mastectomy with reconstruction in January of 2007 that showed no residual tumor in the breast but 1 positive right axillary lymph node. The patient started Arimidex in May 2007 and had ongoing follow-up. In November 2011, the patient noted a "lump to her right upper reconstructed breast at approximately 2:00." Needle biopsy in December 2011 showed invasive carcinoma and the patient underwent a lumpectomy. The lumpectomy pathology report stated, "Breast tissue, right, lumpectomy: poorly differentiated infiltrating ductal cancer." There is no comparison of the current pathology to the previous pathology, as the previous lumpectomy/mastectomy was done at another facility. The patient is being treated at this facility with radiation as if this is a "recurrent/persistent right sided breast cancer." Should this case be classified as a new primary because the pathology report indicates the malignancy was in breast tissue? Or is this actually a chest wall recurrence given the fact that the patient was previously treated with bilateral mastectomies? Should this case be treated as indicated in SINQ 20110111? |
For cases diagnosed 2007 or later, accession two primaries, right breast cancer diagnosed in June 2006 and a subsequent right breast primary diagnosed in December 2011. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Breast MP rules because site specific rules exist for this primary. Start at the MULTIPLE TUMORS module, rule M4. The rules are intended to be reviewed in consecutive order within a module. Accession two primaries, tumors diagnosed more than five (5) years apart are multiple primaries. If the pathology report stated the tumor originated in residual breast tissue, then this is a new tumor and, therefore, a new primary per rule M5. If the pathology report stated the tumor arose in the chest wall and/or there is no designation of residual breast tissue, then this is a regional metastasis and not a new primary. |

20120092 | MP/H Rules/Multiple primaries/Recurrence -- Lung: How many primaries are accessioned if a diagnosis of squamous cell carcinoma of the lung is followed three years later by a diagnosis of adenocarcinoma of the lung if the pathologist reviews all the slides and states the subsequent diagnosis is a recurrence? See Discussion. | 7/12/2007 Left upper lobe lung lobectomy: Squamous cell carcinoma.
3/09/2010 Left lung completion pneumonectomy: Adenocarcinoma, predominantly acinar. The diagnosis comment on the pathology report indicates the previous lobectomy specimen from 2007 was reviewed and "there are areas that appear histologically similar to the current neoplasm. Thus, the findings are most compatible with recurrence."
Despite the difference in histology, is this a single primary per the MP/H Coding Rules, General Information instruction 7 because the pathologist did refer to the 3/9/2010 diagnosis as a "recurrence" of the 7/12/2007 diagnosis after reviewing the slides? |
For cases diagnosed 2007 or later, accession a single primary, left upper lobe squamous cell carcinoma diagnosed 7/27/2007.
The steps used to arrive at this decision are:
Go to the General Information notes for Determining Multiple Primaries for Solid Malignant Tumors in the Multiple Primary and Histology Coding Rules Manual.
General Information Rule 7 states "Use the multiple primary rules as written unless a pathologist compares the present tumor to the "original" tumor and states that this tumor is a recurrence of cancer from the previous primary."
Accession a single primary. Do not apply the Multiple Primary rules because the pathologist compared the 2007 and 2010 slides and determined this was a recurrence and not a new primary. |

20120052 | Ambiguous Terminology/Histology--Heme & Lymphoid Neoplasms: What is the histology code if the final diagnosis is "non-Hodgkin lymphoma NOS," but after further genetic and immunohistochemistry studies were performed the pathology report diagnosis COMMENT section stated the immunohistochemistry findings were "compatible with follicular lymphoma"? See Discussion | Ambiguous terminology is not to be used to code a more specific histology. However the immunohistochemistry results (the definitive diagnostic method for follicular lymphoma) seem to clarify the non-specific diagnosis of non-Hodgkin lymphoma. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Ambiguous terms are not used to code a specific histology. This includes ambiguous terminology used as a result of immunophenotyping or genetic studies. However, a definitive clinical diagnosis can be used to code a more specific histology.
In this example, the histology is coded to non-Hodgkin lymphoma, NOS [9591/3] because the pathology final diagnosis was non-Hodgkin lymphoma, NOS even though it was followed by further genetic and immunohistochemistry studies that were "compatible with" (ambiguous terminology) follicular lymphoma.
However, if there was a subsequent non-ambiguous clinical diagnosis, the histology would be coded to the more specific diagnosis. For example, if the pathology final diagnosis was non-Hodgkin lymphoma, NOS, and there was a subsequent clinical diagnosis of follicular lymphoma or the patient was treated for follicular lymphoma, then the histology should be coded to 9690/3 [follicular lymphoma, NOS]. Document either of these in a text field to support the histology code chosen. Follicular lymphoma is a specific type of non-Hodgkin lymphoma. If you do have a confirmed diagnosis of follicular lymphoma, code that specific cell type per rule PH29.

20120034 | Primary site--Brain and CNS: How is the primary site to be coded if a clinician used an MRI to diagnose a left cerebellar venous angioma? See Discussion. |
According to the WHO Classification of Brain/CNS Tumors, code 9122/0 (venous angioma) does not appear under tumors of the cerebellum (C716). |
Venous angiomas (9122/0) are not reportable wherever they arise. The primary site for venous angioma arising in the cerebellum is C490. The combination of 9122/0 and C490 is not reportable. Venous angioma is a venous abnormality, currently referred to as a developmental venous anomaly (DVA). |
