20100064 | Histology--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].
See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].

20100045 | Histology--Heme & Lymphoid Neoplasms: How is histology coded for a pathologic diagnosis of "B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma" that was clinically referred to as a "double hit lymphoma"? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code histology to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Per the Alternate Names section in the Heme DB, B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is one of the synonyms for for DLBCL.

20130155 | Diagnostic confirmation--Heme & Lymphoid Neoplasms: How do we code diagnostic confirmation if the pathology report states the diagnosis of a skin biopsy is "low-grade B cell lymphoma, most compatible with marginal zone lymphoma," genetic data includes positive rearrangement for immunoglobulin heavy chain gene favor a diagnosis of "B cell lymphoma," and the physician's clinical diagnosis is "cutaneous marginal zone lymphoma"? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code diagnostic confirmation to 3 [positive histology AND positive immunophenotyping studies (9590/3 - 9992/3)].
Immunoglobulin heavy and light chain genes rearranged is listed under Genetics Data in the Heme DB for 9699/3 [extranodal marginal zone lymphoma]. Given the documentation of this positive genetic finding and the positive bone marrow, code diagnostic confirmation to 3.

20110055 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted for a bone marrow biopsy diagnosis of "acute myeloid leukemia (non-M3 type; favor FAB M1), probably arising in myelodysplastic syndrome;" and flow cytometry studies performed the same day were consistent with acute myeloid leukemia? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Ambiguous terminology is NOT used to determine histology for hematopoietic or lymphoid neoplasms. Therefore, the comment that the AML is "probably" arising in myelodysplastic syndrome is not used to determine the histology code. The term "favor" is also an ambiguous term and cannot be used to code histology.
This is a single histology per M2, abstract a single primary when there is a single histology. The histology is coded to 9861/3 [acute myeloid leukemia, NOS]

20130109 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2004 diagnosis of acute myeloid leukemia is followed by a 2013 diagnosis of myeloid sarcoma? See Discussion. |
Patient was diagnosed in 2004 with acute myeloid leukemia [9861/3] and treated with chemotherapy and transplant. Now the patient has a biopsy of an umbilical mass that is positive for myeloid sarcoma (granulocytic sarcoma) [9930/3]. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Accession a single primary, acute myeloid leukemia [9861/3] diagnosed in 2004 per Rule M3.
When there is a myeloid sarcoma diagnosed simultaneously or after a leukemia of the same lineage, it is a single primary. The myeloid sarcoma is actually caused by the AML progressing. The myeloid cells in the bone marrow or blood literally "seep out" and implant in the tissue.

20120044 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient is diagnosed with acute monocytic leukemia in 2009 and in 2011 has biopsy confirmed granulocytic sarcoma of the cerebellum? See Discussion. |
Is this a recurrence of the patient's leukemia? In 2011, the patient is found to have several masses in the cerebellum, biopsy confirmed granulocytic sarcoma. The physician stated this is an "extramedullary relapse of leukemia." The bone marrow biopsy in 2011 was negative.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Accession a single primary per Rule M3. Code histology to 9891/3 [acute monocytic leukemia] diagnosed in 2009 and primary site to C421 [bone marrow].
Per Rule M3 a single primary is reported when a sarcoma is diagnosed simultaneously or after a leukemia of the same lineage. Histology 9891/3 [acute monocytic leukemia] is listed as one of the histologies in the "same lineage." Myeloid sarcoma (9930/3) diagnosed simultaneously with or after acute myeloid leukemia (9861/3) or another leukemia of the myeloid lineage (9840/3, 9865/3-9867/3, 9869/3-9874/3, 9891/3, 9895/3-9898/3, 9910/3, 9911/3 and 9931/3).
NOTE: Under the Alternate Names section of the Heme DB, granulocytic sarcoma is a synonym for myeloid sarcoma.
Per PH10, code the primary site C421 [bone marrow] and code the histology acute myeloid leukemia, NOS (9861/3) or any of the specific AML histologies (9840/3, 9865/3-9867/3, 9869/3-9874/3, 9891/3, 9895/3-9898/3, 9910/3, 9911/3 and 9931/3) when the diagnosis is myeloid sarcoma (9930/3) AND there is a simultaneous or previous diagnosis of acute myeloid leukemia.

20110071 | Primary site: How is this field coded for an adenocarcinoma arising in a chronic perianal fistula without extension to the anal canal, but stated to arise in "ectopic rectal tissue"? See Discussion. | The patient underwent a resection of a perineal mass. Per review of slides it was stated to be "primary mucinous adenocarcinoma arising in a chronic perianal fistula." The adenocarcinoma was invasive into the dermal connective tissue and skeletal muscle, but there was no extension into the anal canal. The discharge diagnosis from the reporting facility called this adenocarcinoma of "ectopic rectal tissue in perianal area."
Should the primary site be coded to skin based on the dermal involvement and lack of anal or rectal involvement? Or, should the primary site be coded to rectum based on the physician's assessment that this adenocarcinoma arose in ectopic rectal tissue? |
For cases diagnosed 2007-2014: Code the Primary Site field to C210 [Anus, NOS]. This is an unusual and rare presentation. According to our expert pathologist, "There is no ideal site code [for] this case. I would code to C210. In this location it can at least be located by anyone who wants to get a look at such lesions. Because of the unusual location of this tumor, I would like to be able to code it to perineum, but it will be totally lost in those site codes as they represent extensive areas beyond perianal (skin of trunk, soft tissue of pelvis, and pelvis, respectively)... I would not code to rectum [because it would be] lost among too many primary rectal carcinomas." |

20091078 | MP/H Rules/Multiple Primaries--Head & Neck: How many primaries should be reported when an invasive squamous cell carcinoma of the right mandibular body (C06.9) was diagnosed in 2004 (treated with surgery and radical neck dissection), and an invasive squamous cell carcinoma of the left buccal mucosa (C06.0) was diagnosed in 2007? See Discussion. | According to the MP/H Rules, it appears Rule M12 would apply since none of the others fit and these would be a single primary. | For cases diagnosed 2007-2014: Based on the information provided, the primary site code for the 2004 primary should be C031 [mandibular gingiva, lower alveolar mucosa, etc.]. The 2007 diagnosis would be a separate primary according to rule M7 because the patient was disease free following treatment for the 2004 diagnosis. C031 and C060 are different at the third character. |

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]. |

20081003 | Reportability--Brain and CNS: For von Hippel Lindau disease with multiple hemagioblastomas, is each hemangioblastoma reportable as a new primary? See Discussion. | Diagnosis of von Hippel-Landau disease, multiple brain surgeries between 2002 and 2007 for recurring hemangioblastomas, 9161/1. This disease manifests as multiple (recurring) hemangioblastomas. | For cases diagnosed 2007-2014:
If the hemagioblastomas occur in sites with different ICD-O-3 topography codes, they are separate primaries.
Please note: Rule M4 in the Benign & Borderline Intracranial and CNS Tumors MP/H coding rules on the SEER website has been corrected to read: Tumors with ICD-O-3 topography codes that are different at the second (Cxx), third (Cxx) and/or fourth (Cxx) characters are multiple primaries.(http://www.seer.cancer.gov/tools/mphrules/benign_brain.html) |
