20130055 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a lymphoma with multifocal bone and epidural involvement but no lymph node involvement if the physician does not clearly state the primary site? See Discussion. | MRI Lumbar spine: Bony metastatic disease most evident at L5, L3 and T10. There is marrow tumor in the posterior elements of T12 and T10. The 14 mm epidural mass represents epidural tumor, likely metastatic, extending into the left intervertebral foramen at T12-L1.
PET scan: Hypermetabolic activity corresponding to epidural mass at the level of T12 and L1 concerning for malignancy. Other small areas of hypermetabolic activity in the left mandible and both femoral necks. There is no hypermetabolic activity corresponding to the areas of abnormal marrow edema in the vertebral bodies which enhanced on MRI scan in the lumbar and lower thoracic spine. No lymph nodes mentioned.
Biopsy epidural mass: Diffuse large B-cell lymphoma with a background of follicular lymphoma, consistent with a large cell transformation. Flow cytometry confirms a mixed large and small cell population of lymphoma (55% large cells).
T12/L1 Bone Biopsy: Bone and marrow with atypical paratrabecular lymphoid infiltrates, suspicious for involvement by follicular lymphoma. Negative for large cell lymphoma. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site of the diffuse large B-cell lymphoma [9680/3] to C809 [unknown primary site] per Rule PH27. The patient has involvement of multiple bones and an epidural mass with no evidence of nodal involvement. Code the primary site to unknown [C809] when multiple organs are involved without any lymph node involvement, even when there is no statement from the physician regarding primary site.

20130031 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a plasmacytoma of the intervertebral disc is diagnosed in 2010 followed by a diagnosis of immature plasma cell myeloma by a right hip biopsy in 2011? See Discussion. |
The patient was diagnosed with intervertebral disc plasmacytoma and had radiation therapy to the pelvic bones in 2010. In 2011 (more than 21 days later) a right hip biopsy revealed immature plasma cell myeloma. There is clinical documentation that this is progression into myeloma. Per the Heme DB (Primary Site(s) and Definition sections) and Rule PH30, in the Heme Manual, the primary site is coded to C421 [bone marrow] and the histology is coded 9732/3 [plasma cell myeloma] when there is a clinical diagnosis of multiple myeloma and/or there is no documentation of a bone marrow biopsy or the results are unknown. This patient did have a bone marrow biopsy that indicates there are an increased plasma cells present; plasma cells represent less than 10%. The skeletal survey and bone scan did not reveal any further lesions. Is this progression of disease because there is only one lesion in the right hip 8 months after the diagnosis of plasmacytoma? Or is this a second primary based on the right hip biopsy that showed plasma cell myeloma and the physician's documentation of disease progression? Plasmacytomas are usually single lesions. Would this disease process have multiple lesions if they are diagnosed at different times? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case is accessioned as two primaries: Plasmacytoma diagnosed in 2010 and plasma cell myeloma diagnosed in 2011 per Rule M10. The patient has a diagnosis of a solitary plasmacytoma (chronic neoplasm) followed by a diagnosis of plasma cell myeloma (acute neoplasm) diagnosed greater than 21 days later. The physician is calling this a progression to plasma cell myeloma even though the bone marrow has less than 10% plasma cells, take this statement as progression or a clinical diagnosis of plasma cell myeloma.

20130015 | Reportability--Heme & Lymphoid Neoplasms: Is essential thrombocytopenia reportable? See Discussion. | Many times essential thrombocytopenia has been coded based on blood counts. Sometimes the discharge summary states thrombocytosis (NOS), and the case is coded to essential thrombocytopenia. Are these cases reportable? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
The following are not alternative names for any reportable disease process:
The diagnosis of essential thrombocythemia is based on blood counts, but is usually a diagnosis made by excluding other myelodysplastic disorders. The following are reportable disease processes:

20130065 | Histology--Heme & Lymphoid Neoplasms: Should the higher histology code associated with grade 1 follicular lymphoma [9695/3] be used rather than grade 2 follicular lymphoma [9691/3] in cases of follicular lymphoma grade 1-2? | Code histology to 9691/3 [follicular lymphoma, grade 2], histology. For follicular lymphoma, when there is a grade such as 1-2 indicated, take the histology associated with the higher grade disease process, even though the lower grade histology code is higher. | 2013 | |
|
20130080 | Primary site/Histology--Heme & Lymphoid Neoplasms: How are the primary site and histology coded when a right neck mass and spinal mass both show B-cell lymphoma, favor Burkitt lymphoma? See Discussion. | 2/5/11 Right neck swelling. Biopsy of mass B-cell lymphoma, favor Burkitt lymphoma.
7/5/11 Hemi-laminectomy, L2-L5 spinal mass: Malignant lymphoma, B-cell phenotype, favor Burkitt lymphoma.
Should the primary site be C779? Is the correct histology Burkitt lymphoma [9687/3] or malignant lymphoma, diffuse large B-cell [9680/3]? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C779 [lymph nodes] per Rule PH22 and the histology to 9591/3 [B-cell lymphoma, NOS].
Code the primary site to C779 [lymph nodes, NOS] when lymphoma is present in an organ and lymph nodes that are not regional for that organ and the origin cannot be determined even after consulting the physician. The patient has involvement of a lumbar spine mass and cervical lymph nodes. Cervical lymph nodes are not regional to the lumbar area of the spine.
Do not use ambiguous terminology to code histology for hematopoietic neoplasms. "Favor" is ambiguous terminology. Therefore, the histology must be coded to B-cell lymphoma and not to diagnosis which is "favored" (Burkitt lymphoma). Remember that ambiguous terminology is only used to determine case reportability, not to code histology for hematopoietic neoplasms.

20130160 | Histology--Heme & Lymphoid Neoplasms: Should the histology be coded to a therapy-related myeloid neoplasm when the physician states the diagnosis of acute myeloid leukemia is secondary to treatment with Imuran? See Discussion. | Patient has a diagnosis of AML for which the physician recommends a bone marrow transplant. The physician indicated the diagnosis is actually a secondary AML due to treatment with Imuran for polymyalgia rheumatica. The physician also stated this is a high risk type of AML. Imuran is not a chemotherapy agent per SEER*Rx. Can the histology be coded as 9920/3 (e.g., Therapy-related acute myeloid leukemia, NOS) when the patient has not been treated with chemotherapy for a reportable disease? The physician is a bone marrow transplant expert who states the AML is therapy-related disease. Bone marrow disease is a listed as a risk for treatment with Imuran. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code this histology to 9920/3 [therapy-related myeloid neoplasm] when the physician states the acute myeloid leukemia is therapy-related.
Therapy-related AML can result from any systemic therapy for benign or malignant diseases. In this case, AML resulted from immune system-suppressing therapy with Imuran for a benign disease, polymyalgia rheumatica. The drugs that induced the AML do not have to be listed in the SEER*Rx database.

20130181 | Multiple Primaries--Heme & Lymphoid Neoplasms: Should Rule M4 or the Heme DB be used to determine whether diffuse large B-cell lymphoma of the large intestine and peripheral T-cell lymphoma of the bone marrow represents one or two primaries? See Discussion. | The Heme DB identifies these as new primaries:
10/12/12 Large intestine, biopsy: Diffuse large B-cell lymphoma.
10/12/12 Bone marrow biopsy: Peripheral T-cell lymphoma. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M15, accession two primaries. According to Rule M15, use the multiple primaries calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. Per the calculator, this scenario represents two primaries.
Assuming the only area of involvement is the large intestine, code the histology to 9680/3 [diffuse Large B-Cell Lymphoma] and per Rule PH24 code the primary site to C189 [colon, NOS]. According to PH24, one is to code the primary site to the organ when lymphoma is present only in an organ.
Rule PH26 applies to the second primary. Assuming the only area of involvement is the bone marrow, code the histology to 9702/3 [peripheral T-cell lymphoma] and code the primary site to C421 [bone marrow]. According to PH26, one is to code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow.
Rule M4 does not apply for this case. Rule M4 applied when you have two or more types of non-Hodgkin lymphoma in the same anatomic location. That is not the case in this scenario.

20130174 | MP/H Rules/Histology--Breast: Given that the current MP/H rules do not recognize specific types of lobular carcinoma, should the histology for an invasive pleomorphic lobular carcinoma be coded to 8022/3 [pleomorphic carcinoma] or 8520/3 [lobular carcinoma]? See Discussion. | The MP/H rules do not seem to recognize specific types lobular carcinomas. As invasive pleomorphic lobular carcinoma is "a very rare and distinct morphological variant of invasive lobular carcinoma," (ncbi.nim.nih.gov). Is this histology best reflected in code 8022/3 [pleomorphic carcinoma] or 8520/3 [lobular carcinoma]? | Code the histology to 8520/3 [lobular carcinoma].
The 4th Edition of the WHO Classification of Tumors of the Breast now describes five variants of invasive lobular carcinoma. These variants are solid type, alveolar, pleomorphic, tubulolobular, and mixed-type. WHO has not yet proposed new ICD-O codes be assigned to these variants. The upcoming solid tumor (MP/H) revisions will include instructions on coding these variants. |

20130201 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported for a patient with a 6/5/12 RUL biopsy that is positive for MALT lymphoma and a 6/7/12 cervical lymph node biopsy that is positive for follicular lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M15, abstract two primaries for this case. According to M15, use the Heme DB Multiple Primaries Calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. The result is two primaries, MALT lymphoma [9699/3] and follicular cell lymphoma [9690/3].
