20120037 | Primary site--Heme & Lymphoid Neoplasms: What is the primary site code for a primary effusion lymphoma if the patient has multiple regions that are positive (e.g., pleural and pericardial effusion and the pleural fluid) for lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per the Abstractor Notes in the Heme DB, primary effusion lymphoma (PEL) is unusual in that the majority of cases arise in body cavities, such as the pleural, pericardial, and peritoneal cavities. Because there are no ICD-O-3 codes for the pleural space, pericardium, or peritoneal cavity, code the primary site to pleura C384 when the neoplasm arises in the pleural cavity, to pericardium C380 when it occurs in the pericardium, and to peritoneal cavity C482 when it occurs in the peritoneum.
Typically only one body cavity is involved. However, if multiple regions are positive for PEL as in this case, code the primary site to C809 per Rule PH27. Rule PH27 indicates one is to code the to primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician in the medical record that he/she that the lymphoma in an

20120036 | Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C779 or C809 when a patient is diagnosed at another facility with mantle cell lymphoma and the staging bone marrow biopsy performed at this facility is negative? There is no available information concerning where the lymphoma originated. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per PH Rule22, code the primary site to C779 [lymph nodes, NOS].
Rule PH22 is a default rule for lymphomas that is used when there is no other information regarding the primary site and the Heme DB does not indicate a primary site under its Primary Site(s) section. Rule PH27, code the primary site to unknown [C809], does not apply. Only use C809 [unknown] as the primary site when there is no evidence of lymphoma in lymph nodes AND the physician documents that the lymphoma originates in an organ(s).

20120035 | Reportability--Pancreas: What is the histology code if well differentiated pancreatic endocrine neoplasms (PanNETs) are reportable?
|
Pancreatic (neuro)endocrine neoplasms (PanNETs) are reportable. The correct histology code is 8240/3. The grade is coded as 1 [well differentiated].

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). |

20120033 | Multiple Primaries--Hematopoietic: How many primaries are abstracted when a patient is diagnosed with essential thrombocythemia in 2007 and a bone marrow biopsy performed on 12/4/2009 shows primary myelofibrosis? See Discussion. |
The patient was diagnosed with essential thrombocythemia in 2007 and was treated with Hydrea. The 2009 bone marrow biopsy showed primary myelofibrosis which the physician states is a transition from the essential thrombocythemia. The Heme DB calls this two primaries. |
This is a single primary, essential thrombocythemia [9962/3] diagnosed in 2007. The 2010 Heme DB and Manual should not have been used to determine the number of primaries in this case. The Heme DB applies only to cases diagnosed 2010 and later. In order to determine the number of primaries, use the rules in place at the time of the subsequent 2009 diagnosis of primary myelofibrosis. Per the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, a diagnosis of essential thrombocythemia [9962/3] followed by a diagnosis of primary myelofibrosis [9961/3] is a single primary. |

20120032 | MP/H Rules/Histology--Melanoma: How is the histology coded for an invasive melanoma stated to have a "superficial spreading growth pattern"? See Discussion. |
Some facilities in our reporting region submit pathology reports that document invasive melanoma cases with a subtype stated to be a "growth pattern." The MP/H rules state that we are not to use the term "pattern" to code the histology of invasive tumors. However, applying this rule means the more specific histology will not be recorded for any of these cases. Can the term "growth pattern" be a more specific histologic type for invasive melanomas when no other information is available? |
Code the histology as superficial spreading melanoma [8743/3]. For cases diagnosed 2007-2014, the steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules manual. For a melanoma primary, use the Melanoma Histology rules to determine the histology code because there are site specific rules for cutaneous melanomas. Start at Rule H1. The rules are intended to be reviewed in consecutive order within the applicable Module. Code the most specific histologic term when the diagnosis is melanoma, NOS [8720] with a single specific type, superficial spreading in this case. The subtype of this invasive melanoma is "superficial spreading." A change will be made to Rule 9 in next update to indicate "growth pattern" can be used to describe an invasive histology. |

20120030 | MP/H Rules/Histology- -Melanoma: What is the correct histology code if the final diagnosis for an excisional biopsy specimen is reported as "malignant melanoma, superficial spreading type" but the under the "cell type" section in the CAP protocol layout of the pathology report it lists "cell type: epithelioid"? See Discussion. |
The MP/H rules do not address the concept of "cell type" for melanomas when the pathologist uses the CAP protocol to report findings and the cell type listed in that section of the report differs from the specific cell type mentioned in the final diagnosis. Does a case have two specific cell types when the final diagnosis and the "cell type" sections of a single pathology report indicate two more specific melanoma histologies? Pre-2007 SINQ entries indicate the cell type should be coded. However, if it differs from the specific cell type listed in the final diagnosis does it matter? Do the MP/H rules still take the cell type into account? |
Code the histology to malignant melanoma, superficial spreading type [8743/3] based on the final diagnosis. For cases diagnosed 2007 or later, the steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules manual. For a melanoma primary, use the Melanoma Histology rules to determine the histology code because there are site specific rules for cutaneous melanomas. Start at Rule H1. The rules are intended to be reviewed in consecutive order from Rule H1 to Rule H10. The rules are intended to be reviewed in consecutive order within the applicable Module. Code the more specific histologic term when the diagnosis is melanoma, NOS [8720] with a single specific type (i.e., superficial spreading) mentioned in the final diagnosis. The final diagnosis takes precedence over the CAP protocol. The CAP protocol may be used when it provides additional or noncontradictory information, but that does not apply in this case. |

20120029 | Primary site--Lung: What is the code for primary site if a small cell carcinoma presents as mediastinal masses? | Code the primary site to main bronchus [C340].
Primary small cell carcinoma in the thymus/mediastinum is rare. A bronchial lesion with extension into the mediastinum is much more likely. In a case like this, it is difficult to be sure exactly where the tumor arose, however, it is recommended the default site be the main bronchus when there is no information to the contrary.

20120027 | MP/H Rules/Histology--Colon: How is histology coded if a patient has two frank invasive adenocarcinomas in one segment of the colon and multiple tubular adenomas and hyperplastic polyps throughout the entire colon without a diagnosis of familial polyposis [FAP]? See Discussion. | Does Rule H19 apply which indicates the histology is coded to 8221 [adenocarcinoma in multiple adenomatous polyps] because there are multiple polyps (number not specified) throughout the colon? Does tumor have to arise in at least one of the adenomas in order to apply Rule H19? Or, does Rule H22 apply which indicates the histology is coded to 8140 [adenocarcinoma, NOS] because the adenocarcinomas are both frank invasive adenocarcinomas and not adenocarcinoma arising in an adenoma? |
Code the histology as adenocarcinoma, NOS [8140/3].
For cases diagnosed 2007 or later, 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) and go to the Colon Histology rules to determine the histology code for this case. The Module you use depends on the behavior and number of tumors identified in the primary site.
Start at the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY Module Rule H15. The rules are intended to be reviewed in consecutive order from Rule H15 to Rule H24. Stop at the first rule that applies to the case you are processing. Code the histology when only one histologic type is identified. In this case, the only histology present was adenocarcinoma, NOS [8140/3].
Rules H17 through H21 do not apply in this case because there is no malignancy arising in any of the adenomas or polyps scattered throughout the colon. |

20120025 | MP/H Rules/Multiple Primaries--Brain and CNS: How many primaries are abstracted if a patient was diagnosed with metastatic malignant melanoma to the brain in 2003 and subsequently was diagnosed with meningeal melanomatosis? See Discussion. | Meningeal melanomatosis has a separate ICD-O-3 code, but is also a very rare form of melanoma. | This is a single primary coded to the site of the original melanoma. The brain and meninges are both metastatic sites. The MP/H Rules do not apply to metastases.
This case was sent to the melanoma physician specialists. The physician stated that, in this case, the meningeal involvement is secondary to the brain involvement (metastatic spread). Whenever brain metastases are diagnosed, the meningeal spread is metastatic. |
