20140089 | Multiple primaries--Heme & Lymphoid Neoplasms: Should the 2014 diagnosis be abstracted as a new primary since it is not mantle cell lymphoma and all of the types listed in the differential diagnosis would be a new primary? See discussion. |
Mantle cell lymphoma diagnosed in 1997 which was treated with chemotherapy. Now in 2014 a 'relapse' of non-Hodgkin lymphoma. They do a biopsy of the pericardium, which is called low grade B cell non Hodgkin lymphoma. See comment. The comment says histochemical stains are reviewed and findings are consistent with involvement by a CD5 positive low grade B cell lymphoma. Lack of cyclin D1 and SOX-11 positivity as well as negative IGH-CCND1 FISH analysis essentially rule out mantle cell lymphoma. The morphologic and immunophenotypic features of this disorder are not specific for any lymphoma subtype. The differential includes CLL, marginal zone lymphoma, and lymphoplasmacytic lymphoma. If this is coded NHL, NOS (9591) it is the same primary as seq. 1 and would not be abstracted. |
This is the same primary, the mantle cell lymphoma.
Differential diagnoses cannot be used to assign histology. For the 2014 diagnosis, the only histology that can be assigned is 9591/3 for non-Hodgkin lymphoma, NOS. (CLL, mantle cell lymphoma and lymphoplasmacytic lymphoma are all NHL's.)
Compare the 1997 diganosis of mantle cell lymphoma with the 2014 diagnosis of non-Hodgkin lymphoma. Start with Rule M1. The first rule that applies is Rule M15, which instructs you to use the multiple primaries calculator. Enter 9673/3 and then 9591/3 and then calculate. The result is same primary.
If at a later time one of the differential diagnoses is confirmed, apply the rules again.

20140017 | Multiple Primaries--Heme & Lymphoid Neoplasms: 2012 path report for removal of an "axillary mass" which consists of 80% diffuse large B-cell lymphoma (DLBCL) and 20% follicular lymphoma. In the original manual, Module 6 instructed us to code as a single primary, DLBCL. However, the multiple primary calculator says each disease is a separate primary. When I looked them up in the data base, I did not get an option to review a current manual. Can you please advise? |
Code as a single primary with histology Diffuse Large B-Cell Lymphoma.
In this case, there are two NHLs in the same location at the same time. Apply Rule M4, this is one primary. Per Note 5 under Rule M4, go to Rules PH11and PH15 to assign primary site and histology.
Rule PH11 states to code to the site of the origin (axillary mass) and to diffuse large b-cell lymphoma (9680/3) when DLBCL and any other non-Hodgkin lymphoma (follicular in this case) are present in the same location at the same time.
Using the multiple primaries calculator in this situation will give you two primaries, which is the wrong answer. Use the rules before using the calculator.
To get to the manual, go to the "Help me code for dx year." section. Choose 2010 or later and the most current manual will appear. We recommend that you save a copy of the PDF on your computer. |

20140068 | Surgery of Primary Site--Corpus uteri: What is the correct surgery code to assign for dilation and curettage (D&C) for an in-situ endometrium (C541) primary? The code to use for the cervix uteri (C530-C539) is specified, but not for the corpus uteri (C540-C549). |
Assign code 20 for endometrial D&C for in situ cancer of endometrium. |

20140071 | Reportability--Lung: One of our facilities has a case they are not really sure how to report.
This patient came in for a double lung transplant due to COPD which occurred on 1/27/14. At time of transplant, the team found out the donor hospital had identified a small nodule in the right lower lobe donor lung, which they biopsied and deemed negative. However, the slides were reviewed and felt to represent adenocarcinoma. The team performed a right lower lobe lobectomy of the donor lung before transplanting into the patient.
So, we are not really sure how to handle this case. The adenocarcinoma actually belongs to the donor patient from another hospital, however, they actually didn’t identify it at that facility as their pathology was negative for a malignancy. |
This very interesting case is not reportable to either facility. Since the right lower lobe nodule was resected prior to transplantation, the case does not belong to your patient. Ideally, the cancer should be assigned to the donor; however, donor information is confidential. |

20140020 | Reportability--Breast: Is ADH/DCIS reportable? Final Dx for left Breast biopsy: Atypical epithelial proliferation (ADH/DCIS). Comment: Sections show small focus of atypical epithelial proliferation with features of atypical duct hyperplasia/low grade duct carcinoma in-situ. |
ADH/DCIS is reportable. DCIS (duct carcinoma in situ) is a reportable neoplasm. When DCIS is stated as the final diagnosis, report the case. | 2014 | |

20140002 | Reportability--Appendix: Is a pathologic final diagnosis of an appendix with "well-differentiated neuroendocrine tumor (carcinoid)" reportable? See discussion. | SINQ 20130027 states that "well-differentiated neuroendocrine tumor" of the appendix is reportable (8240/3) while "carcinoid" tumors of the appendix are not reportable (8240/1). Please explain the difference between "well-differentiated neuroendocrine tumor" of the appendix and a "carcinoid" of the appendix. | Well-differentiated neuroendocrine tumor of the appendix is reportable. The difference is terminology. "Carcinoid" is listed in ICD-O-3 as a /1 for appendix making it non-reportable.
When both terms are used, ask for clarification from the pathologist. Failing that, accept the reportable terminology and report the case. |

20140082 | MP/H Rules/Histology--Testis: How should histology be coded for a testicular teratoma with somatic type malignancy (adenocarcinoma)? See discussion. |
11/8/2013 Rt orchiectomy: teratoma with somatic type malignancy (adenocarcinoma). 5/2/2014 Abdominal mass excision: metastatic teratoma involving matted lymph nodes. Patient age at diagnosis is 31.
Per web search, a teratoma with somatic type malignancy is a rare type of tumor. Should the histology be coded to 8140/3? This seems to conflict with SINQ 20120085, which indicates a testicular mature teratoma in an adult is malignant, and in this example, it was also the portion of tumor that metastasized. |
Assign code 9084/3, listed in ICDO as teratoma with malignant transformation.
Our expert pathologist consultant states that this is a very rare situation. The non-germ cell components are believed to arise out of the teratoma portions, and are seen in only of few percent of teratomas. They are given the designation "teratoma with somatic type malignancies" (WHO). |

20140072 | Reportability--Head & Neck: Would this be reportable and if so what histology would be coded? Soft tissue mass left cheek excision reveals Carcinoma Ex Pleomorphic Adenoma Non-Invasive with focal vascular invasion. Margins clear. |
Carcinoma ex pleomorphic adenoma (Ca-ex-PA) is reportable. Assign 8941/3. The WHO classification of head and neck tumors defines Ca-ex-PA as an epithelial malignancy arising in a benign pleomorphic adenoma. Most of these originate in the parotid gland but can also arise in other salivary glands. |

20140040 | Reportability/Primary Site--Lip: Is a right lower lip (NOS) squamous cell carcinoma reportable when the microscopic description states the tumor arises from the epidermis and extends through the dermis? See discussion. |
We are having difficulty determining whether the primary site is lip, NOS (C009) or skin of lip (C440). Usually we look for a statement of “skin” or “mucosa” in the microscopic description if the specimen label is only lip, NOS as instructed by the previous SINQ 20051049. Is a statement of "epidermis" or "dermis" in the microscopic description enough to indicate carcinoma is arising in the skin of the lip (C440) and thus not reportable? |
This case is interpreted as skin of lip and not reportable. According to our expert pathologist consultant, the pathologist in this case "is specifically saying "epidermis" and "dermis" and I would have to think it is skin, and thus not reportable." |

20140014 | First course treatment/Surgery of Primary Site--Anus: Would infrared coagulation be coded as treatment for AIN III of the anus/anal canal? See discussion. | SINQ 20051064 indicates infrared coagulation is not treatment for cancer. Internet search explains that infrared coagulation delivers heat to destroy the tissue so it can be removed. In our region it is currently used to treat internal and external anal low grade squamous intraepithelial lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL). While it is understandable that this wouldn't be coded as treatment for an invasive anal primary, could it be treatment for an in situ tumor? If it is treatment, should it be coded under Surgery code 15 | The answer to SINQ 20050164 still applies. Do not code infrared coagulation as cancer treatment. It is used to coagulate blood vessels and not to destroy cancer tissue. | 2014 |
